What is the maximum allowable speed when operating under restrictive conditions?

In situations where trains are operating under restrictive conditions, the maximum allowable speed is set to ensure safety and reduce the risk of accidents. This speed limit considers factors such as visibility, track conditions, and the proximity of other trains.

The designated maximum speed of 20 MPH under restrictive conditions is established to allow adequate time for train crews to react to unexpected circumstances, such as obstacles on the track or signals indicating a change in track use. This speed provides a balance between operational efficiency and safety, making it critical for maintaining safe train operations when conditions do not permit normal speed.

Understanding the importance of adhering to these speed limits is fundamental in train dispatching, as they are designed to protect both the train crews and passengers while ensuring that the railway system operates smoothly under various circumstances.
