Question

After applying the required number of hand brakes on a train which has been laid up on a grade, the proper test of whether the hand brakes will hold the train is to ________.

Answer 1

To test if hand brakes will hold a train on a grade, release the air brakes and ensure the train remains stationary, indicating the hand brakes are effective.

Step-by-step explanation:

The proper test of whether the hand brakes will hold a train that has been laid up on a grade is to release the air brakes and ensure that the train does not move. After the hand brakes have been applied, the train is checked for security by temporarily reducing the braking force applied through the air brake system.

If the train remains stationary, it indicates the hand brakes are adequately preventing the train from moving. This is an essential safety measure to ensure the train does not roll away uncontrolled, potentially causing a dangerous situation.
