Caboose

A caboose is a manned North American railroad car coupled at the end of a freight train. Cabooses provide shelter for crew at the end of a train, who were long required for switching and shunting, and to keep a lookout for load shifting, damage to equipment and cargo, and overheating axles.

Originally flatcars fitted with cabins or modified box cars, they later became purpose built with projections above or to the sides of the car to allow crew to observe the train from shelter. The caboose also served as the conductor's office, and on long routes included accommodation and cooking facilities.

A similar railroad car design, the brake van, was used on British and Commonwealth railways. These provided the additional function of serving as a supplemental braking systems for trains not fitted with a continuous braking system, and keeping chain couplings taut.

Cabooses were used on every freight train until the 1980s, when safety laws requiring the presence of cabooses and full crews were relaxed. Developments in monitoring and safety technology such as lineside defect detectors and End of Train Device resulted in crew reductions and the phasing out of caboose cars. Nowadays, they are generally only used on rail maintenance or hazardous materials trains, or on heritage and tourist railroads.

The caboose provided the train crew with a shelter at the rear of the train. The crew could exit the train for switching or to protect the rear of the train when stopped. They also inspected the train for problems such as shifting loads, broken or dragging equipment, and hot boxes (overheated axle bearings, a serious fire and derailment threat). The conductor kept records and handled business from a table or desk in the caboose. For longer trips, the caboose provided minimal living quarters, and was frequently personalized and decorated with pictures and posters.
