What should the train crew do if track route instructions change from previous instructions received?

When the track route instructions change from previous instructions received, it is essential for the train crew to contact the Employee in Charge to confirm the validity of the new instructions. This step is crucial because it ensures that the crew is operating with the most current and accurate information regarding the track route. Confirming with the Employee in Charge helps to prevent any potential misunderstandings or mistakes that could arise from operating on outdated or incorrect instructions.

In rail operations, safety and adherence to protocols are paramount, and confirmation serves as a safeguard. It provides an opportunity for the crew to clarify any uncertainties regarding the change and ensures that all necessary precautions are taken to operate safely and efficiently.

The other options do not prioritize the vital step of verification. For instance, continuing on the new route without confirmation could lead to safety hazards if the new instructions were incorrect or misinterpreted. Notifying passengers, while important for customer communication, does not address the operational safety required in this situation. Updating the track bulletin is also necessary but should occur after validating the new instructions to ensure accuracy. Therefore, contacting the Employee in Charge for confirmation is the correct and safest action for the train crew to take under these circumstances.
