If you encounter a flashing green signal on a curve, what action should you take?

The correct action to take when encountering a flashing green signal on a curve is to stop the train as required by the Manual of Operations (MAL) and wait for the Train Operating Document (TOD) to change. A flashing green signal typically indicates that there are conditions that demand caution, particularly in complex or potentially hazardous situations like curves where visibility is limited or speeds may need to be adjusted for safety.

By stopping the train, the engineer ensures that they can assess the situation carefully before proceeding. It allows for a thorough evaluation of any signals, track conditions, or other safety factors that may not be immediately visible while in motion. Waiting for the TOD to change provides clear guidance on how to proceed safely, ensuring that all operational protocols are being followed correctly.

This action prioritizes safety and operational integrity, which is essential in train operations especially when navigating through curves that may present additional risks.
