What is the maximum speed a train can operate when re-entering a block?

When a train is re-entering a block, it must operate at restricted speed until further notice. This requirement is in place to ensure the safety of the train crew, passengers, and any work being conducted within the block.

Restricted speed is defined as a speed at which a train can stop within half the distance of its sighting range, allowing the crew to respond appropriately to any obstructions or signals that might be encountered. This is particularly important in areas where there may be unknown variables, such as maintenance work, other trains, or track conditions that haven't been officially communicated.

By adhering to restricted speed when re-entering a block, the train crew maintains a level of caution that promotes safety during potentially unpredictable situations. This practice ensures that they have ample time to react if any issues arise, aligning with the overall safety protocols within rail operations.
