What should a train operator do when stopping a local train at a home signal indicating STOP on an upgrade?

When stopping a local train at a home signal that indicates STOP on an upgrade, it is essential for the operator to keep the full service brake applied. This is the correct approach because maintaining full service brake pressure ensures that the train remains securely stopped and does not roll backward down the upgrade due to the gradient. The train's weight can cause it to move unexpectedly, and applying the service brake helps counteract this risk.

In situations where the brake is released or not sufficiently applied, the train might lose its stopping momentum, leading it to roll, which can create hazardous conditions for both the train and surrounding infrastructure. By keeping the full service brake applied, the train operator ensures that appropriate precautions are taken against unintended movement, especially in the context of a stop signal that requires a halt. This approach reflects standard operating protocol for safety during critical stops.
