What actions should be taken when a train enters a block with no governing signal?

When a train enters a block with no governing signal, it is essential to proceed at restricted speed until the next signaling point. This practice ensures the safety of the train and any other trains that may be in the vicinity. Restricted speed allows the engineer to stop the train within half the range of vision, which is crucial in the absence of signals that guide speed and movement.

Proceeeding at restricted speed is particularly important in scenarios where visibility may be limited or when there could be obstructions on the track. By doing this, the train crew can respond appropriately to unexpected conditions, ensuring that they can stop the train safely if necessary. This method of operation is a key aspect of maintaining safe train operations in situations where signal authority is lacking.

Taking actions such as speeding up or continuing at normal speed can lead to unsafe situations, including collisions or accidents, particularly if another train is present in the block. These alternatives disregard the fundamental principle of safety that governs train operations. Waiting for instructions could lead to unnecessary delays and might not be practical in all situations, especially if it causes the train to remain on a potentially hazardous block. Thus, proceeding at restricted speed is the most cautious and responsible action to take.
