What is the maximum speed restriction for train operators in a yard when not otherwise indicated?

The maximum speed restriction for train operators in a yard, when not otherwise indicated, is 10 MPH. This speed limit is established to ensure the safety of personnel, equipment, and operations within the confines of a yard. Yards are typically busy environments where trains are assembled, disassembled, and serviced; hence, lower speed limits are crucial to allow for safe maneuvering around obstacles, other rail vehicles, and workers who may be present. The lower speed also grants the train operator more time to react to unexpected situations, reducing the risk of accidents and injuries.

In contrast, higher speed limits might be more appropriate in less congested areas or along mainline routes, but in a yard setting, the priority is safety and control at lower speeds.
