RAILROAD SWITCHING AND TERMINAL ESTABLISHMENTS
This category covers establishments engaged primarily in the furnishing of terminal facilities for rail passenger or freight traffic for line-haul service and in the movement of railroad cars between terminal yards, industrial sidings, and other local sites. Terminal companies do not necessarily operate any vehicles themselves, but they may operate the stations and terminals. Lessors of railway property are classified in SIC 6517: Lessors of Railroad Property.

Industry Snapshot
The roughly 3,000 stations and track terminals in the United States during the 2000s served about 15 large freight railroads and more than 600 small, regional railroads. As mass transit systems continued to spread across America, rail tracks and terminals shared by more than one railroad company became an increasing concern. A train going just 30 mph needs two-thirds of a mile to stop; a train going 50 mph needs 1.5 miles. High-speed trains traveling in excess of 125 mph also were being placed into the rail system.
The human error factor, which accounted for the majority of train switching accidents, was being eliminated from the industry. As trains became more electronically controlled, safety for passenger and freight cargo rose dramatically. Approximately 80 percent of railroad tracks in the United States used a technology employing electromechanical relay signal systems. However, wireless microprocessors that used computer signals were...
