When securing locomotives, what is the first step to take?

The first step in securing locomotives is to place the throttle in IDLE. This action ensures that the locomotive is not able to accelerate accidentally. By placing the throttle in the IDLE position, you reduce the risk of any unintended movement, which is critical for safety when working around locomotives or preparing them for further operations.

Once the throttle is in IDLE, then it becomes practical to proceed to the other securing steps, such as applying the hand brakes or removing the reverser handle. These subsequent actions contribute further to ensuring the locomotive is firmly secured and cannot move.

Understanding this order of operations is essential for safety and operational integrity in locomotive management.
