Determine the minimum number of hand brakes required

The requirement to determine the minimum number of hand brakes necessary is essential for safely securing a train at a location other than its terminal. When a train needs to be left on a grade or in a location where it may be susceptible to movement, ensuring it is securely held in place is paramount. This involves an assessment of factors such as the train's weight, the gradient of the track, and any potential environmental influences that could affect its stability.

By calculating the appropriate number of hand brakes to apply, personnel can mitigate the risk of unintended movement, thus ensuring both the safety of the train and the surrounding area. This procedure helps maintain control over the train and addresses the safety protocols that are required in such situations.
