Mr. Justice Clark
delivered the opinion of the Court.
These six appeals involve, the validity of an order of the Interstate Commerce Commission permitting the merger of the Pennsylvania Railroad Company and the New York Central Railroad Company (Penii-Central) pursuant to § 5 (2) of the Interstate Commerce Act, as amended, 41 Stat. 481, 49 U. S. C. § 5 (2). In its original order of April 6, 1966, the Commission found that the merger might divert a substantial amount of traffic from the Erie-Lackawanna Railroad Company (E-L), the Delaware and Hudson Railroad Company (D «fe H) and the Boston and Maine Corporation (B «fe M), three smaller competing carriers designated as the “protected railroads” by the Commission. These protected railroads had filéd under § 5 (2) (d) of the Act applications for inclusion in both this merger and in Norfolk & W. Ry. Co. and New York, C. & St. L. R. Co.—Merger, 324 I. C. C. 1. In the latter case inclusion of E-L and D «fe H has been recommended and, together with B «fe M, is pending before the Commission. The applications of the protected roads in the Penn-Central proceeding have been held in abeyance pending decision in the Norfolk proceeding.
On the merits of the Penn-Central merger, the Commission found that the service the protected railroads “render their shippers is essential and the public interest dictates that [such service] be .preserved.” The Commission concluded “that immediate consummation of the proposed merger would be consistent with the public interest, if conditions are imposed to obviate impairment or serious weakening” of the three lines. Without such conditions or the inclusion of the protected roads in a major system, the Commission further found, it would be doubtful if the “three carriers could withstand the competition of the applicants merged, and, unless they are protected during, the period necessary to determine their future, we would not authorize consummation at this time, even though approving the merger.” 327 I. C. C. 475, 532. It, therefore, applied, sua sponte, certain conditions to the immediate consummation of the merger which were “designed to prevent any loss of revenue over the three railroads [the protected railroads] as a direct result of immediate consummation of this merger.” Its “approval of the merger for undelayéd consummation” was made “subject... to the conditions specifically described in appendix G,” ibid., which was attached as an appendix to the April 6, 1966, order, and which we likewise attach as an Appendix here. The Commission, apparently because of the necessity for the conditions and the urgency of the merger, required compliance with Appendix G even though it had neither the bénefit of a report from a Hearing Examiner thereon, nor the advantage of a hearing before the Commission itself. These conditions detailed the protection which must be given the protected railroads and made them a prerequisite to the consummation of the merger.
The Commission, therefore, not only found that protection of the three railroads was necessary, but fixed the terms thereof and required compliance prior to permitting the' merger. There was nothing tentative about Appendix G. The conditions were divided into two general categories and provided that: (1) On traffic for which the protected railroads are “competitive factors” the merged company shall not, pending final determination of the inclusion proceedings, provide any new or changed routing practice,, freight rates, or service which would divert or tend to divert traffic from routes in which the protected railroads, or any of them, participate or participated at the time of the merger. And (2) the protected railroads would be indemnified by the merged company against revenue losses by reason of the merger. Appendix G to the order detailed the manner in which such indemnity would be calculated and provided for the accelerated processing of complaints as to. new or changed routes, practices, rates, or services. Section 7 of Appendix G provided that if the merged company did not accede to all of the conditions, the merger would be deferred for two years or “such time as the Commission may determine to be necessary to protect, the interests of D & H, B & M and E-L.” And § 8 provided that the conditions “shall be construed, administered and enforced with the view to protecting the E-L, D & H and B & M and the shipping public which depends upon them for transportation, against the effects of the merger for the period and purposes set forth above.”
Thereafter, and without a hearing, but apparently on the objection of most of the parties, the Commission on September 16, 1966, modified its April 6 order and reopened' the hearing. 328 I. C. C. 304. The objectors, among other things, pointed to the fact that the conditions of. Appendix G were made without any notice or hearing and would create irreconcilable conflicts between the protected carriers and others adversely affected by the merger. In reopening the hearing the Commission limited it to the conditions imposed in Appendix G-, the prevention of possible manipulation of such conditions and the enlargement of the indemnity provision to include capital loss. In the reopening order of September 16, Í966, the Commission left intact its order of April 6, 1966, as to the undelayed consummation of the merger, continued in effect the ban on new or changed routes, practices, and rates as to traffic in which any of the protected railroads participated, but lifted the indemnification condition until further order, at which time any such provision found necessary could be made retroactive to the date of the merger. None of the previous findings, as to the necessity for the immediate imposition of the conditions included in the original order, were amended or withdrawn. The traffic conditions alone were left in effect.
This suit was filed on September 7, 1966, and arose upon the complaint of E-L and other railroads seeking an interlocutory injunction to restrain the consummation of the merger. A three-judge court was convened, 28 U. S. C. § 2284, and thereafter it declined, by a divided vote, to grant the interlocutory injunction. Erie-Lackawanna Railroad Co. v. United States, 259 F. Supp. 964. The appellants sought a stay from Mr. Justice Harlan who referred the application to the Court and it was granted on October 18, 1966. At the same time we expedited the oase for consideration. 385 U. S. 914. The sole question before us is whether, in light of the findings as to the necessity for interim protection for the so-called protected railroads, the Commission erred in permitting the consummation of the merger prior to and without awaiting determination of the inclusion proceedings. We believe that the Commission erred in approving the immediate consummation of the merger without determining the ultimate fate of the protected roads. We, therefore, reverse the judgment and remand the case to the District Court with . instructions to remand the matter to the Commission for further proceedings in accordance with this opinion.
I.
Questions not here decided.
At the outset we make it clear that we do not pass on the validity of the merger, the special conditions of Appendix G, the modified order of the Commission, or the peripheral points posed by the various parties. We hold only that under the uncontradicted findings of the Commission it was necessary for it to conclude the inclusion proceedings, as to the protected railroads, prior to permitting consummation of the merger.
II.
The merger, its background, its participants and relative position.
The Penn-Central merger has been under study and discussion by the Commission for some 10 years. After the initial study was completed in 1959, Central withdrew-, from the plan and began negotiations for a merger with" the Chesapeake and Ohio Railway Company (C «fe 0) for joint control of the Baltimore and Ohio Railroad Company (B «fe 0). However, when at a later date.C «fe 0 had contracted for the purchase of some 61% of B «fe 0 stock, Central gave up its plan and renewed negotiations with Penn. The two roads signed an agreement of merger in 1962. The New York, New Haven and Hartford Railroad'Company (NH) approached Penn and Central for inclusion in the plan but was given a deaf ear. The merger agreement provided that all properties, franchises, etc. .(permitted, by respective state law), would be transferred to the merged company and appropriate stock exchange, debt arrangements, etc., effected. '
As the Commission found, the merger would “create an hour-glass shaped system flared on the east from Montreal, Canada, through Boston, Mass., to Norfolk, Va., and on the west from Mackinaw City, Mich., through Chicago, Ill., to St. Louis, Mo.” 327 I. C. C., at 489. It would operate some 19,600 miles of road in 14 States between the Great Lakes, with a splash in Canada on the north, and the Ohio and Potomac Rivers' on the south. After the two systems are connected as planned and' new and expanded yards are provided, the merger will consolidate trains now moving separately between the same points. The combined systems will have a substantial amount of parallel track-age and routes, with 160 common points or junctions. Terminals will be consolidated, present interchanges between the two systems will be eliminated and only the most efficient yards and facilities of the respective systems will be utilized. The merger plan calls for 98 projects that will intermesh their long-haul traffic at key points, creating a nonstop'service between the principal cities with “locals” coyering the multiple-stop routes and branch lines. It is estimated that enormous savings in transit time can be effected; Certain chosen yards — such as Selkirk — will be remodeled and modernized into electronically operated yards with capacities of from 5,000 to 10,000 cars per day. The through trains to the West will be formed at Selkirk and those from the West broken up for dispatch to terminals' or consignees in New England, New York, and northern New Jersey. The. plan calls for some New York City traffic to be routed over Central’s Hudson River East Shore line to lessen cost. By consolidating traffic on fast through lines, filling out trains, re-routing over the most efficient routes, eliminating some interchanges and effecting other improvements, the merged company will reduce by 6,000,000 the number of train miles operated. A single-line service will be operated between more points, with less circuity and less switching. The plan'álso calls for 31 daily trains to be withdrawn from the Pennsylvania with seven new ones added, leaving a total of 319 trains daily.
The Pennsylvania is the largest and Central the third largest railroad in the Northeastern Region. Together the operating revenue of the two roads was - over $1,500,000,000 in 1965. Their net income in 1964 totaled almost $57,000,000 and in 1965 ran in excess of $75,000,000. In 1963 the total net was barely.$16,000,000. The cost of operation of the two systems runs $90,000,000 a month and their working capital was some $72,000,000 in. 1965. As of December 31, 1963, their combined investments were $1,242,000,000. The Pennsylvania and Cehtral systems are each made up of underlying corporations, As of the date of the Examiners’ Report the merged company would have ownership interest in 182 corporations and 10 railroads under lease! Thirty-six of the corporations are rail carriers! in six of which the merged company would have a voting control. All six are Class I railroads.. It would likewise control six Class II railroads, five switching and terminal railroads, a holding company, five car-leasing companies, four common carriers and 34 noncarrier corporations.
The NH is the sixth largest railroad in the Northeastern Region and the largest in New England. On a national basis it ranks fourth among passenger-carrying railroads and is one of the largest non trunkline' fréight roads. It has some 1,500 miles of railroad in four States — Massachusetts, Rhode Island, Connecticut, and part of New York. NH has been in reorganization under § 77 of the Bankruptcy Act, 47 Stat. 1474, as amended, 11 U. S. C. § 205, since 1961. While its gross revenues have run in excess of $120,000,000, it has run deficits since 1958; During the trusteeship its deficits have run from $12,700,000 in 1962 to $15,100,000 in 1965.
hH HH I — I
The protesting parties, their setting m the Northeastern Region and their position on the merger.
Altogether some 200 parties participated in the proceedings before the Commission, some in support of and others in opposition to the merger. None of the appellant railroads challenge the merits of the merger; however, appellants Milton J. Shapp and the City of Scranton both attack the merger on its merits. Aside from Penn-Central and NH, there are 10 other carriers involved in this proceeding.
Three of these are the protected carriers — B & M, I) & H and E-L. B & M operates a freight and passenger service in . Maine, New Hampshire, Vermont, Massachusetts and' New York over some 1,500 miles of road. It has suffered consecutive deficits in net income for some years and has not appealed from the decision of the District Court. D & H operates about 750 miles of road with some 600 in New York, less than 50 in Vermont and the balance in Pennsylvania. Its net income in 1965 was $5,000,000, its highest year since 1960. E-L operates some 3,000 miles of railroad located in New Jersey, New York, Pennsylvania, Ohio, Indiana and Illinois. Its net income was over $3,000,000 in 1965 but it. suffered heavy deficits in the seven preceding years. As we have previously noted, these three railroads have filed applications for inclusion in both this case and in Norfolk & W. Ry. Co. and New York, C. & St. L. R. Co.—Merger, 324 I. C. C. I. The Commission has withheld action, on the inclusion of E-L, B & M and D & H, in Pénn-Central until there is a final determination of their inclusion proceeding with Norfolk and Western (N & W). In the Jatter proceeding Commissioner Webb filed his report on December 22,1966, récommending the inclusion of E-L and D & H in the N & W system but was unable to prescribe terms for inclusion of B & M — this was left to private negotiation between the railroads. On argument here the Commission .has indicated that it anticipated entering a final order in the matter by Juiy or August 1967. If this is favorable these, three roads would be included in the N & W system, which has indicated its acquiescence in such a plan.
Six additional railroads involved here are the C & 0, B & 0; the Central of New Jersey (CNJ), the Reading Company, the Norfolk and Western, and the' Western Maryland Company (WM). The C & O-B & O system is the result-of a control proceeding in 1962. See Chesapeake & O. Ry. Co.—Control—Baltimore & O. R. Co., 317 I. C. C. 261, sustained, sub nom, Brotherhood of Maintenance of Way Employees v. United States, 221 F. Supp. 19, aff'd, per curiam, 375 U. S. 216 (1963). Together these two roads operate some 10,000 miles of railroad. Their lines extend from Michigan through Ohio and West Virginia to Virginia and from Chicago, Ill., and St. Louis, Mo., to Rochester, N. Y., and Washington, D. C. Their net operating income in 1965 totaled over $80,000,000. In addition, B & O owns 38 %■ voting control of'Reading which in turn controls CNJ. Reading has 1,200 miles of railroad in eastern Pennsylvania with net. operating revenue of some $8,000,000 in 1965. CNJ has 514 miles of railroad extending from Scranton, Pa., to. Jersey City, N. J. In 1965 it had a net operating deficit in excess of $3,000,000. C & O-B & O also own jointly 65% of the voting stock of WM. The latter has 741 miles of railroad extending, from Connellsville, JPa., and Webster Springs, W. Va., to Baltimore, Md. In 1965 its net operating income was nearly $8,500,000.
N & W has 7,000 miles of railroad extending in a double prong from Des Moines, Iowa, and Kansas. City, Mo., on the west to Buffalo, N. Y., and Pittsburgh, Pa., on the east and from Cincinnati, Ohio, and Bristol, Va., on the west to Hagerstown, Md., and Norfolk, Va., .on the east. Its net operating income. for 1965 was approximately $118,000,000.'1 As we have noted, an inclusion proceeding is now pending under which B & M, D & H and E-L seek inclusion in the N & W system.
On October 11, 1965, C & O-B & O and N <fe W filed an application with the Commission asking approval of their merger into a single system and offering to include B & M, D & H, E-L, the Reading and CNJ therein, subject to various'conditions. If this were effected and the Penn-Central-NH merger were effected, the. Northeastern Region would then have two giant systems, i. e., Penn-Central and C & O-B & O-N & W.
Only one additional railroad remains a party here, the Chicago and Eastern Illinois Railroad Company (C & El). It has approximately 750 miles of railroad operating between Chicago, Ill., St. Louis, Mo., and Evansville,Ind., with a net operating income of nearly $3,500,000 in. 1965. The Missouri Pacific Railroad Company has already been authorized by the Commission to make C & E I a part of its system. The fear of C & E I here was that the Penn and Central merged would be a more formidable competitor than the Central alone and it, accordingly, sought the imposition here of special routing and traffic conditions.
The only other appellants are the City of Scranton, Pa., and Milton J. Shapp. Scranton is served by E-L, D & H and CNJ. It fears that the merger will have adverse effects upon the city and therefore opposes the merger. Shapp sues as a citizen and stockholder of Penn and is likewise in opposition to the merger.
The United States has filed a memorandum in which it does not “quarrel with the merits of the Penn-Central merger proposal itself.” The agencies of the Executive Branch, the Solicitor General reports, “believe that the merger is in the public interest and that its consummation should be promptly effected.” This view, however, is based on the assumption “that a place in the emerging pattern of consolidation in the Northeast can be found for the lesser roads of the region.” It is the Commission’s approval of the immediate consummation of the merger prior to the completion of the proceedings to determine the place of the lesser roads to which the United States objects. It contends that since the very survival of the three protected, railroads is threatened by the Penn-Céntral merger, the Commission must first provide protection for them until their absorption by “a major system like Norfolk and Western.” - To this end the United States suggests that we hold the case to enable the Commision to conclude the related proceedings which it now has under consideration. The United States concludes that: “Only if the Commission is unable to promptly resolve the problems resulting from the merger would we deem it appropriate to urge this Court to reach the merits of the appeals and reverse the judgment below.”.
The appellant railroads take varying positions all short of attacking the merits of the merger. The three protected railroads contend that the merger should not be consummated prior to the final determination of their inclusion in some major system or the enforcement of effective protective conditions in the interim. Judicial, review, they say, of the protective conditions would otherwise be illusory. The C & O-B & O group and the N <fe W system maintain that the conditions of the April 6, 1966, order give the protected railroads a vested interest in the Penn-Central merger which would result in the protected railroads diverting traffic to Penn-Central which would normally have gone to them. They say, as does the United States, that the conditions were drawn without the benefit of notice and hearing, are deficient and enforcement thereof would be to their detriment. C & EI points to what it calls inconsistent findings as to the benefits it will have “of intensified competitive efforts” by its connecting carriers on routes in competition with Perin-Central. It contends that the indemnity conditions would “compound the economic injury” which would befall the C &, E I as a result of the merger and which prompted'it to request protective measures.
IV.
The national transportation policy and practices of the Commission thereunder.
This Court has often pointed out that the national transportation policy “is- the product of a long history of trial and error by Congress . . . .” McLean Trucking Co. v. United States, 321 U. S. 67, 80 (1944). In that case it found that the Transportation Act of 1920 “markéd a sharp change in the policies and objectives embodied in those efforts.” Ibid. In that Act the Congress directed the Commission to adopt a plan for consolidation of the railroads of the United States into “a limited number of systems.” 41 Stat. 481 (1920). Consolidation would be approved by the Commission upon a finding that the transaction was in harmony with and in furtherance of the complete plan of consolidation and that the public interest would be promoted.' But the Commission was warned that “competition shall be preserved as fully as possible.” Ibid. The initiation of this unification, however, the Congress left wholly with the ■ carriers. The Commission was given ho power to compel mergers. This pattern was carried forward in the Transportation Act of 1940, 54 Stat. 898; however, § 5 of the former Act was amended to authorize the Commission to approve carrier-initiated proposals which it found to be consistent with the public interest and upon just and reasonable conditions. Under § 5 (2) (d) additional power was given the Commission to condition its approval of a merger upon the inclusion, upon request, of other railroads operating in the territory involved. As,we said in County of Marin v. United States, 356 U. S. 412 (1958), “the result of the [1940] Act was a change in the means, while the end remained the same. The very language of the amended ‘unification section’ expresses clearly the desire of the Congress that the industry proceed toward an integrated national transportation system through substantial corporate simplification.” Id., at 417-418. The Commission has, therefore, not proceeded by or under “a master plan” for consolidation in the various regions. Following this procedure the Commission has refused to consolidate the Northeastern Region railroad merger or control proceedings into one case. See Chesapeake & O. Ry. Co.— Control-Baltimore & O. R. Co., supra, at 265-266, and Norfolk & W. Ry. Co. and New York, C. & St. L. R. Co.—Merger, supra, at 18. Also Brotherhood of Maintenance of Way Employees v. United States, 221 F. Supp. 19, at 29-31; aff’d per curiam, 375 U. S. 216 (1963).
It is contended that the order here is fatally defective for failure to comply with § 5 (2)(b) of the Act which requires the Commission to “enter an order approving and authorizing such transaction, upon the terms and conditions, and with the modifications, so found to be just and reasonable.” The claim is that by leaving the indemnity provisions open for future, determination the Commission did not meet the requirements of the section. Once a valid order is entered by the Commission, it, of course, has the power to retain jurisdiction for the purpose of making modifications that it finds necessary in the light of subsequent circumstances or to assist in compliance with prior conditions previously required or, of course, to correct any errors. The Commission also has power under § 5 (9) of the Act to make certain supplemental orders and under § 17 (3) may correct clerical ■ errors in certificates. We do not find it necessary to pass upon the question of naked power in the Commission to' do what has been done here. Even assuming that it does have that power, we find that its order approving immediate consummation of the merger is insupportable on its findings.
V.
Conclusions.
The Commission found in its April 6, 1966, order that the protected railroads would be adversely affected to a “serious degree” by the Penn-Central merger; that they would be “severely handicapped” in providing required transportation to the highly industrialized areas that they serve, which service is “essential” and “the public service dictates that it be preserved.” It then held that immediate consummation of the merger would be consistent with the public interest only if the conditions of Appendix G were immediately imposed. And, significantly, it concluded that even though it approved the merger, consummation of it would not be permitted unless the protected railroads “are protected during the period necessary to determine their future . . .'.” 327 I. C. C., at 529, 532. But after this suit was brought and strong opposition to Appendix G was voiced, the Commission, on September 16, 1966, withdrew all of the conditions of Appendix G save the traffic ones. ' This left the protected railroads without sufficient protection according to the Commission’s own findings. This was done apparently because of the vehement objections of the appellant railroads that Appendix G would cause havoc rather than give shelter. We cannot say, as did the District Court, that the September 16, 1966, order meant nothing more than that the traffic conditions left imposed by it were in themselves sufficient to protect the three protected railroads during the interim between the merger and the decision as to their future in one of the major railroad systems. This interpretation runs in the face of not only the prior findings enumerated above but the specific terms and conditions of Appendix G found to be necessary to prevent “impairment or serious weakening” of the three carriers. Id,., at 532. Indeed, rather than being tentative, the requirements of Appendix G were rigidly fixed and established for the entire period preceding inclusion of the protected roads in some major system. The finding of consistency with the public interest was predicated entirely upon the unqualified acceptance of Appendix G by Penn-Central. Otherwise the merger would be put off for two years. In its effort to expedite the merger the Commission failed to provide the very protection that it at the same time declared indispensable to the three roads. This leaves the ultimate conclusion — that prompt consummation of the Penn-Central merger clearly would be in the public interest— without support and it falls under the Commission’s own findings.
In view of these facts and since none of the findings of the Commission were disturbed, attacked, or amended, we believe it was error to permit the merger to be effected. And we also note that even in the ultimate order of approval dated September 16, 1966, the Commission pointed out that its “finding [as to the merger being consistent with the public interest] was that, if the immediate consummation were to be authorized E-L, D & H and B & M would require special protection during the pendency of their petitions for inclusion in a major system.” Nevertheless, in spite of this confirmation of its finding, the Commission ordered the merger immediately consummated without the “special protection” afforded by Appendix G. Having found that the finding of consistency with the public interest could only be sustained by the imposition of the Appendix G “special protection,” the Commission failed to meet its statutory obligation when it arbitrarily removed the special conditions of Appendix G while leaving the prior finding-standing.
In view of the patent invalidity of the order permitting immediate consummation of the merger and in light of the present status of the proceeding before the Commission, we can only conclude that it is necessary that the decision as to the future of the protected railroads and their inclusion, in a major system be decided pribr to consummation of the Penn-Central merger. This is especially true since the findings and recommendations of Commissioner Webb, as to the inclusion of the three protected railroads, are now under submission to the full Commission and a decision should be reached thereon by July or August 1967, we are advised by counsel. This short time would have little effect upon the ultimate consummation of the merger — which has been in the making for some 10 years now — and if it resulted in the future of the protected railroads being finally decided, serious losses to them would be obviated. Furthermore, there would .be no occasion for the conditions of Appendix G to be imposed and hearing and decision on this highly controversial matter would not be necessary insofar as the three protected railroads are concerned. Finally, such action would provide the solution to the problem of the necessary and indispensable protection to . the three railroads that the Commission found prerequisite to the merger.
Furthermore, the serious charge that the conditions of Appendix G were imposed without notice and hearing would in a large part be dissipated by this course of action. As to the three protected roads it would be entirely obviated if and when their fate is determined. As to the other railroads affected, the Commission could more quickly conclude its present hearing and make a decision as to the effect of the merger upon them and the protection, if any, required.
This disposition is also buttressed by the fact that should the immediate consummation of the merger be permitted and at a later date neither the interim conditions nor the inclusion proceedings be disposed of favorably to the continued existence of the merger, the only remedy remaining would be to set it aside and unscramble the - consolidation. It is said that this does not follow since only the indemnity terms are at issue and they involve only money. This is blinking at reality. The fact is that traffic, trackage, terminals, etc., as well as financial and corporate structures can and will, beyond doubt, be quickly combined, changed, abandoned, or consolidated. The only condition now imposed for the maintenance of the status quo is the provision against any change of routes, traffic, rates, etc., as to business in which the three protected roads participate. They are comparatively small lines located for the most part in northeastern coastal States and would, percentagewise, be a small part of the total routes, trafile, rates, etc., of the whole Penn-Central system. There would be no restriction as to other routes, traffic, rates, etc., as well as all other operations of the merged company, including terminals, warehouses, etc., financial and corporate structures. The plan that the Penn-Central proposes to follow, as we have briefly sketched it, indicates not only major changes but quick action. Our experience with other mergers, and common sense as well, indicate that the “scrambling” goes fast but the unscrambling is interminable and seldom .effectively accomplished.
The Penn-Central merger has been studied for a decade.. Indeed, the parties to the merger agreed to it over five years ago and it has been under Commission consideration ever since that time. This is, of course, the more reason for expedition. We note and give weight . to the estimates of the Commission that the inclusion proceedings of the three roads in the N & W should be concluded in “a relatively short time.” Our remand should, therefore, entail only a1 very short delay before the Commission. If its order is attacked in court the hearing there can be expedited, as was this one, and an early determination made. We do not believe that this is too high a price to pay to make as certain as human ingenuity can devise, a just and reasonable disposition of this matter for all of the parties. After all, it is the largest railroad merger in our history and if not handled properly could seriously disrupt and irreparably injure the. entire railroad system in the northeastern section of the country — to the great detriment not only of the parties here but to the public conveniénce and necessity of the entire Nation.
The judgment of the District Court is reversed and the cause is remanded with instructions that it be remanded to the Commission for further proceedings not inconsistent with this opinion. ⅛ so or<¡ered.
APPENDIX TO OPINION OF THE COURT.
Appendix G.
Provisions for the Protection of E-L, D & H, and B <fc M.
1. Pending final determination of the petitions for inclusion filed by E-L, D & H, and B & M in this proceeding and in Finance Docket No. 21510 et al., or such other period of time as the Commission may prescribe, herein- ' after called the protective period, and on traffic for which E-L, D & H and.B & M are competitive factors, the . merged company shall not publish or provide for any new or changed routing practice and/or freight rates or services, either locally or jointly with other carriers, which would divert or tend to divert traffic from routes in which E-L, D & H or B & M, now participates, or participated at the time this merger application was filed, or take any action or engage in any practice or conduct contrary to the purpose and general objectives of this condition as explained in this report.
For the purpose of illustrating — but in no way limiting — the application Of this condition, .the following specific provisions are prescribed:
A. During the protective period, and as to the described trafile, the railroads which shall make up the merged system will be considered separate railroads, as they now are, for the purposes of establishing new routes or rates or privileges and changes in present routes, rates or privileges.
B. When any of the described freight traffic is delivered to carriers of the merged system, it shall be allocated among the routes of the system in accordance with practices employed by the system’s railroads at the time this merger application was filed.
C. Where through routes and joint rates are now in existence via any component railroad of the merged system and E-L, D & H or B & M, the participation therein of such components shall be maintained during the protective period with the same vigor as such components have heretofore exercised in competition with each other and other carriers, to the end of preventing noticeable diversion from such routes to any other route in which the merged company participates.
D. The merged company for the protective period shall , agree to joint rates and. divisions thereof on its freight traffic interlined with E-L, D & H or B & M under terms no less advantageous to E-L, D & H and B & M than are the terms which those three carriers now have with the component carriers of the merged system, and, in the event of any changes in such joint rates, the divisions shall not be changed in any manner which will result in E-L, D & H or B & M receiving proportionally less than they now receive on joint rates with such component carriers.
E. In conjunction with E-L, D & H and B & M, the merged company shall, during the protective period, keep open all routes now in force for the transportation of freight over the lines of the three companies and the component carriers of the merged system; shall maintain thereon service equal to or better than that being given on the date this merger application was filed; shall improve such- service, to the extent • within its power, at least as necessary to make the said through routes fully competitive with other routes in which, the merged company participates; and, where joint rates are now in effect or were in effect when this merger application was filed, it shall maintain such rates; and where change in those rates becomes appropriate, changes shall conform to the requirement of provision D above.
2. The term “competitive factor” shall be construed to mean that at the date of this order or at the time this merger application was filed, E-L, D & H or B & M was both participating in the- particular route, rate or service and was handling traffic thereon.
3. E-L, D & H and B & M shall be indemnified by the merged company under the circumstances and according to, the plan specified, in the report, supra. '

A; All controversies arising under this appendix shall be determined with finality by the Interstate Commerce Commission in the manner indicated below.
B.' (1) Except as to section 3, supra, whenever E-L, D & H or B & M considers that these protective conditions are being violated, or that a violation will result from the effectuation of a tariff publication in which the merged company participates, they may (individually or collectively) file a complaint with the Commission, Board of Suspension, and with the merged company, specifying the rate, route, practice, privilege, or such matters constituting the alleged violation and setting forth in .a statement verified by an appropriate official of the complainant all the data giving rise to the complaint.
(2) In the event the Board of Suspension shall determine that, as to the matter complained of, E-L, D & H or B & M is a competitive factor (as defined in these conditions), it shall in the case of a tariff publication not yet effective, suspend the tariff forthwith for, the protective period (as defined in these conditions), and shall conduct an investigation into the matter complained of; and if the alleged violation is found not to exist, the Board shall thereupon order the suspension removed; and, in all matters not involving a tariff not yet in effect, the Board shall investigate the matters complained of; and, if in any investigation, it finds that these protective conditions are being violated, it shall order the cancellation of the violative tariff provisions or, where a tariff is not involved, the termination of the violative conduct. Orders of the Board shall have force and effect as orders of this, Commission and shall be enforced as such.

6. Notwithstanding the provisions of sections. 1, 2, 3, 4, and 5, an agreement pertaining to the interests of E-L, D & H and/or B & M may be hereinafter entered by the merged company and the protected-carriers, or any of them, which shall supersede the protection provided by such sections to the extent the agreement does not violate the provisions of the Interstate Commerce Act or the Commission’s rules and regulations thereunder.
7. In the event applicants fail to accede to the above-named conditions, consummation of the proposed merger will be deferred for 2 years or such time as the Commission may determine to be necessary to protect the interests of D & H, B & M and E-L.
8. These conditions shall be construed, administered and-enforced with the view to protecting the E-L, D & H, and B & M and the shipping public which depends upon them for transportation, against the effects of the merger for the period and purposes set forth above.
9. These conditions are to be applied in addition to the standard conditions set out in appendix I hereof.
“Competitive factor” was defined as any particular route, rate, or service on which any of the “protected railroads” were handling traffic at the time the merger application was filed or at the date of the order..
We ineludé it in this discussion since the Commission intends to include it in the PennTCentral system as soon as terms and conditions are agreed to.or fixed.
In the matter of the New York, New Haven and Hartford Railroad Company — Debtor, No. 30226 U. S. D. C. Conn.
This- proceeding involved the merger of the Nickel Plate. E-L sought inclusion in this proceeding along with B & M-and D & H. After E-L had withdrawn its application the. Commission found that the merger “should have no harmful effects” on B & M and D & H. The Commission retained jurisdiction for five years to permit E-L, B & M and D & H to again petition for inclusion. See, .324 -I, C. C. 1, 19-31. Each of the roads so petitioned and it is this, inclusion proceeding that is how before the Commission.
Among these, CNJ claims it has. been deprived of a hearing on the effect on it of the inclusion of the NH in the Penh-Central merger. As the Commission points out, however, the terms and conditions of the NH’s inclusion are subject to further proceedings and the Commission has specifically given to CNJ leave “to seek protection for. [its] traffic and gateways,” at that time. 327 I. C. C., at 527. Moreover, CNJ also says, it has not been afforded a hearing on its claim that the merger will also deprive it of important overhead coal traffic now delivered by CNJ to D & H at Wilkes-Barre, Pa. This might be lost, it alleges, because of the direct connection between D & H and N & W which will be available over the track-age rights that Penn-Central is being required to grant D & H. We know nothing of the merits of these claims and, of course, indicate no decision thereon. However, we assume that the Commission will in each instance afford the CNJ an opportunity to be heard concerning them.
