What area must not be occupied when a train is approaching a station platform?

When a train is approaching a station platform, it is crucial that the area adjacent to the platform, specifically the tracks, remain clear of any other trains. This is primarily because of safety concerns; an incoming train may not be able to stop in time if there are other trains occupying the adjacent tracks, as this can create a risk of collision or derailment.

Additionally, the movement of the train can create a strong wind gust and may also cause vibrations that could affect stability or safety in the surrounding area. Maintaining a clear area allows for safe operations and reduces the risk of accidents or incidents.

In contrast, other elements—such as emergency vehicles, passengers, and maintenance personnel—have protocols in place that dictate how they operate around platforms and train movements. Emergency vehicles typically have designated routes and timing to ensure they do not interfere with train operations. Passengers are expected to be mindful when entering or exiting but are allowed on the platform itself. Track maintenance personnel work under strict safety regulations and often have procedures to ensure they are clear of any approaching trains.
