Also in 1910, C&O interests bought control of the Kanawha and Michigan (K&M) and Hocking Valley Railway (HV) lines in Ohio, with a view to connecting with the Great Lakes through Columbus. Eventually antitrust laws forced C&O to abandon its K&M interests, but it was allowed to retain the Hocking Valley, which operated about in Ohio, including a direct line from Columbus to the port of Toledo, and numerous branches southeast of Columbus in the Hocking Coal Fields. But there was no direct connection with the C&O's mainline, now hauling previously undreamed-of quantities of coal. To get its coal up to Toledo and into Great Lakes shipping, C&O contracted with its rival Norfolk & Western to carry trains from Kenova. W. Va. to Columbus. N&W, however, limited this business and the arrangement was never satisfactory.
