Cab car

A cab car is a special sort of railroad passenger car used in push-pull operations. The majority of the cab car is indistiguishable from a regular passenger car, but features a full driving cab built into the end of the coach. It has all the controls and guages necessary for operating the locomotive of the train. Externally, the car also includes a horn, bell, plow and all of the lights that would normally be on a locomotive.The cab car is placed at the end of the train from which the train's locomotive can be remotely controlled. This allows for push-pull operation with a faster turnaround time for trains, by avoiding having to physically turn around the train or locomotive.

The cab car differs from other driving cabs, such as the British driving van trailer, in that it keeps the appearance of a passenger car. In fact, the cab end of a cab car includes a doorway so that it could sit in the middle of a passenger train like a regular car if necessary. Some commuter rail agencies routinely use cab cars in place of regular passenger carriages on trains.
