opinion: Walter D. BEEZER v. BALTIMORE & OHIO RAILROAD COMPANY, a Corporation, Appellant.
  No. 10945.
  United States Court of Appeals Third Circuit.
  Argued March 19, 1953.
  Decided April 16, 1953.
  Vincent M. Casey, Pittsburgh, Pa. (Marvin D. Power, Margiotti & Casey, Pittsburgh, Pa., on the brief), for appellant.
  E. V. Buckley, Pittsburgh, Pa. (Mercer & Buckley, Pittsburgh, Pa., on the brief), for appellee.
  Before BIGGS, Chief Judge, and MARIS and GOODRICH, Circuit Judges.
  PER CURIAM.
  The appellant contends that the judgment of the court below should be reversed, asserting that no actionable negligence was shown on its part which was the proximate cause of the accident, that the verdict was against the weight of the evidence, that the evidence as to the impaired physical condition of the plaintiff was insufficient, and that the verdict was excessive. Every contention made is fully answered by the opinion of Judge Stewart. See 107 F.Supp. 361. Since we perceive no error, the judgment of the court below will be affirmed.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "transportation". Your task is to determine what subcategory of business best describes this litigant.
