What is the maximum speed permitted on curved tracks in yards?

The maximum speed permitted on curved tracks in yards is 10 mph because this limit is established to ensure safety and stability during train operations. Curved tracks present unique challenges due to the forces acting on the train, including centrifugal force, which can cause instability at higher speeds. Maintaining a speed of 10 mph helps reduce the risk of derailments and allows operators to maintain better control over the train.

This speed limit is particularly important in yard operations, where there are often other trains, equipment, and personnel present. By adhering to this maximum speed, train operators can ensure a safer environment while maneuvering through curves where visibility may be limited and the dynamics of the train can change rapidly. Additionally, following these speed guidelines aligns with regulatory standards designed to protect both train crews and ground staff in busy rail yard settings.
