There was a brief period in railroad tech in which air brakes relied on positive pressure direct from a compressor on the locomotive. If one car disconnected, it would result in a complete loss of braking power across the entire train. This could be fixed on the fly by shutting the open valve cock at the breakaway.
 
(The successor to the system, the Westinghouse system, uses negative pressure to apply the brakes; Meaning a breakaway would activate the brakes along the entire train, including the disconnected stock)
