What must a crew do if they hear a train approaching while working?

When a crew hears a train approaching while working, the appropriate action is to clear the area immediately. This is essential for the safety of all crew members and ensures that they are not in any potential danger from the oncoming train.

In roadway worker protection programs, the priority is to maintain a safe working environment. Hearing a train means that the crew must act swiftly to move to a safe position away from the tracks to avoid any accidents or injuries. This protocol is in place to ensure that workers are protected from the hazards associated with train operations, which can include high speeds and limited stopping distance.

While signaling the approaching train can sometimes be part of safety protocols, the immediate priority must be to remove oneself from harm's way. Similarly, checking with the Rail Worker In Charge (RWIC) may be a part of other procedures, but when a train is heard, the first action should always be to clear the area to ensure everyone's safety promptly.
