Railroads: Rail car air brake system

Connections are made between cars by flex hose and quick disconnects called ______. They are designed to disconnect automatically as cars pull away from each other during uncoupling.

Gladhands

7

Railroads:

A hand brake wheel or ratchet is located at the "B" end of the car. "B" stands for ____ end of the car

Brake

8

Railroads: Rail car air brake system
-True or false?
You may manually separate the air hoses when uncoupling cars.

False,
Make no attempt to separate the air hoses when uncoupling cars. Separation underpressure can be violent and cause serious injury. Disconnection will occur with car separation, and if you are positioned at the cut lever, you are at a safe distance.
