If a train experiences a loss of third rail power and is stopped between stations, what is NOT necessarily required?

Discharging passengers is not necessarily required if a train loses third rail power and stops between stations. In many instances, the safety of the passengers and the specific circumstances dictate whether they should be evacuated. For example, if the train is in a safe location where emergency services can reach it or if assistance is on the way, it may be safer to keep passengers onboard until help arrives rather than evacuating them onto the tracks.

On the other hand, notifying the rail control center and waiting for assistance are critical actions to ensure that the situation is managed effectively and safely. Checking all systems following a power loss is also essential to assess the condition of the train and determine the next steps. Thus, while passenger safety is paramount, discharging them is not always considered an immediate requirement in all cases of power loss.
