What must happen when there are intervening road crossings when shoving equipment?

When shoving equipment through areas with intervening road crossings, it is essential to ensure those crossings are protected. This is crucial for safety, as it helps prevent accidents involving vehicles or pedestrians that may inadvertently cross the tracks when a train is moving in reverse. Protecting these crossings typically involves having flag personnel or other warning systems in place to alert motorists and ensure that the area is clear before the train proceeds. This process is a standard safety protocol in railway operations to maintain awareness of potential hazards and safeguard both personnel and the public.
