When laying up a train at signal R8X, what is required?

When laying up a train at signal R8X, the requirement to apply all handbrakes is essential for ensuring the safety and stability of the train while it is stopped. When a train is laid up, particularly on a grade or in conditions where it may be prone to movement, using all available handbrakes helps to secure the train effectively, preventing unintended rolling.

In many operating procedures, regulations dictate that the use of all handbrakes mitigates the risks associated with weather, track conditions, and potential mechanical failure of braking systems. By engaging all handbrakes, the crew ensures redundancy in securing the train, thus providing an additional layer of safety.

Given this understanding, the requirement for all handbrakes to be applied is consistent with safe operational practices in the railroad industry. It acknowledges the need for thoroughness when securing a stationary train, particularly in signaling areas where potential hazards, such as grades or nearby rail traffic, may be present.
