Railway air brake
<snip>
An air brake is a conveyance braking system actuated by compressed air. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on March 5, 1868. The Westinghouse Air Brake Company (WABCO) was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted.
The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure signals each car to release the brakes. A reduction or loss of air pressure signals each car to apply its brakes, using the compressed air in its reservoirs.

This is very weird at best, trains cross back and forth between Canada and the U.S.A. all of the time. Why have different air braking standardized by the Department of Transportation (DOT)?
Why completely abandon a crippled train on the hill? Who is the idiot who made this decision?
