How should a train operator move a car with inoperative air brakes?

A train operator must prioritize safety and effective control of the train at all times. When dealing with a car that has inoperative air brakes, it is critical to couple it to a car or cars that have functioning brakes. This is because the good brakes on the coupled cars will help provide the necessary stopping power. It ensures better control of the train during movement, particularly when navigating gradients or encountering any obstacles on the track.

Having the functional brakes will allow the train operator to manage the speed more effectively and reduce the risk of runaway conditions, which can occur if the inoperative car were to be moved without any braking capability. Additionally, this coupling method aligns with standard operating procedures designed to maintain safety standards while transporting rolling stock with mechanical deficiencies.

The other methods mentioned pose safety risks and are not advisable in practice. Manual brakes alone may not provide sufficient control for a full consist, uncoupling and pushing a car can lead to difficulties in maneuvering, and moving at maximum speed increases risks significantly. Therefore, coupling an inoperative car to those with operational brakes is the safest and most effective approach.
