What is the recommended procedure for moving a car with faulty air brakes?

The recommended procedure for moving a car with faulty air brakes is to attach it to another car with functional brakes. This approach is crucial for ensuring the safety and control of the moving train. By coupling the defective car to another that has operational brakes, it allows for stopping capability, thus preventing potential accidents or derailments that could occur if the car were to be moved independently.

Utilizing a car with functional brakes is particularly important because it addresses the risk associated with insufficient braking power, which is critical in train operations. Moving the faulty car under its own power is not safe and would likely lead to a dangerous situation if any emergencies arise during transit.

The other methods, such as pushing it with another train or moving it at high speed, pose additional risks and could exacerbate the situation. Leaving the car until repairs are made ensures that safety protocols are strictly followed, but in cases where movement is necessary, attaching it to a functioning car is the most appropriate and safest method.
