If a train operator suspects the third rail is dead, what should they do?

When a train operator suspects that the third rail is dead, one of the initial steps they can take is to open the cab door and observe the car lights. This method provides valuable information about the power status and overall functionality of the train. If the train's lights are off or flickering, it indicates a loss of power, suggesting that the third rail may indeed be non-operational. This visual check can help the operator confirm whether there is an issue with the train's power supply.

In cases where the train lights are operational, it may suggest that the issue is localized, potentially within the train rather than the third rail itself. By observing the car lights first, the operator can gather necessary information and decide on further actions without immediately summoning maintenance or performing a more involved inspection that might be premature.

While calling for maintenance could certainly be necessary if suspicions are confirmed, gathering preliminary information first can lead to more effective troubleshooting. A manual inspection of the rails might also be a later step, but it requires leaving the train and may not be safe or practical without proper procedures. Switching power to backup systems may be an option later on, but confirming the state of the primary power source is more critical initially.
