What speed must a train operator maintain when bypassing a station platform?

When bypassing a station platform, the train operator must maintain a speed of 15 mph. This specific speed limit is crucial for safety and operational reasons. Operating at this speed ensures that the train can react appropriately to any unexpected circumstances that may arise, such as pedestrians or vehicles near the platform.

Maintaining a lower speed also helps to minimize the risk of accidents as the train approaches the station area, where additional caution is necessary due to the proximity of passengers and staff. It allows for better control of the train, enabling the operator to make any necessary adjustments in a timely manner.

In other situations, speeds above this threshold would potentially pose a greater safety risk, as the train's large mass and momentum make it challenging to stop quickly. Therefore, this speed is set not only to comply with regulations but also to ensure the safety of everyone involved.
