Where is the Angle Cock located?

Where is the Angle Cock located?

• A. At each end of a locomotive or car.
• B. On the brake cylinder side of the brake rigging.
• C. In the caboose's interior control panel.
• D. On the locomotive's cab roof.

Answer: (A)

The angle cock is the air-brake isolation valve that controls air flow into the train line, and it must be accessible at the ends of equipment. Placing it at each end of a locomotive or car allows you to isolate or charge the train line from either side, which is essential during coupling, uncoupling, testing, or when you need to shut off a section without disturbing the rest of the train. That’s why it’s located at the ends rather than inside a caboose panel, on the brake cylinder side of the brake rigging, or on the locomotive cab roof.
