The Belt Line was a former CSX owned freight railroad branch industrial line on the west side of Hamilton, Ohio extending from Belt Junction JCT connection with CSX Cincinnati Terminal Subdivision and the CSXIndianapolis Subdivision.

After the rail line closed, it was converted to bicycling and hiking path.

By 1940, Champion’s Hamilton mill rail yards had more than 20 miles of track with several steam locomotives shuttling cars around the clock.

HBR began losing business to trucks after World War II.

It had no locomotives or cars and was worked in succession by the CH&D, the B&O, CSX and, after 1988, by privately-owned short line companies Great Miami & Western Railway then US Rail.
