The General Code of Operating Rules (GCOR) is a set of operating rules for railroads in North America. The GCOR is used by nearly every Class I railroad west of the Mississippi River, most of the Class II railroads, and many Short-line railroads.
Overview
The GCOR rules are intended to enhance railroad safety. The rules cover employee responsibilities, signaling equipment, procedures for safe train movement, dealing with accidents and other topics that directly and indirectly affect railroad safety. Some railroads modify the GCOR rules to suit their specific operations.
The GCOR is supplemented by System Special Instructions, Timetables, Hazardous Materials Instructions, Air Brake and Train Handling Instructions, and General Orders. These documents are issued by each individual railroad. System Special instructions, Timetables, and General Order can modify or amend the General Code of Operating Rules. GCOR 1.3.2 states that General Orders replace any rule, special instruction, or regulation that conflicts with the general order.
Most railroads are using the Sixth Edition, Effective April 7, 2010.
