What is the maximum speed for shoving cars or engines on a controlled siding for freight trains?

The maximum speed for shoving cars or engines on a controlled siding for freight trains is established to ensure safety and control during operations. The correct answer indicates that the speed limit is set at 20 MPH. This speed allows for manageable control of the train movements, balancing safety and efficiency.

Controlled sidings serve as areas where trains can pass, allow for switching operations, or enable other trains to safely maneuver around stationary cars. Operating at this maximum speed ensures that crew members have sufficient time to react to any unexpected situations that may arise. It also helps maintain the integrity of the equipment and the safety of personnel involved in these operations.

Understanding the significance of these speed restrictions is crucial for maintaining safety standards in rail operations, ensuring that everyone involved is aware of their surroundings and the limitations of their vehicles.
