I still don't get it on what happened, reduced brake capacity.
My understanding is that the air part of an air brake system holds the brakes off the wheel thread. When the emergency brakes are tripped the air is released and the brakes contact the wheels. When the TO applies the brakes entering a station part is dynamic above 10-15 mph then its all air brakes to a stop. In this scenario a hostler was doing a two car move and applied the brakes to find they had none to speak of. So this are the possibility:
1 - The air could not be released, hence no brake application. (Controller or brake valve problem.)
2 - Brake shoes worn down that they don't make contact with the wheel.
3 - Mis-adjusted brake slack adjuster or brake linkage not connected.
Looking at those three puts it in the house of poor maintenance. Lack of personnel, lack of training or just negligence. So, in a 6-car set how many brakes are needed?
I am not usually negative but this is getting trying.
