When approaching a caution signal, what should the train operator do?

When approaching a caution signal, the train operator should approach at the allowable speed. This means that while the operator is aware of the caution signal, which indicates that there may be potential restrictions or hazards ahead, they are still permitted to continue moving but must do so at a controlled and safe speed.

This practice ensures that the train operator can react appropriately to any changes in the track conditions or signals that may arise as they approach the caution signal. This controlled speed allows for a gradual assessment of the situation, giving the operator time to make necessary adjustments, whether it involves slowing down further or preparing for a more significant change in signal status.

Pacing oneself at the allowable speed not only satisfies operational protocols but also prioritizes safety for both the train crew and passengers, as well as the integrity of the rail infrastructure.
