The caboose was far more than the end of a train, serving as the conductor’s portable office, a safety post, and living and working space for train crews. The conductor used it to handle the paperwork needed to ensure a train arrived safely, delivered its people, baggage, or freight, had enough fuel, and remained rail worthy. Its cupola allowed the conductor and brakeman to watch for problems such as hot or glowing brakes, sparks, fire hazards, smoke, hot grease, and other trouble along the train. It also carried the conductor, brakemen, and flagmen, especially on freight trains where the only other crew were at the engine and on passenger trains where seats were reserved for paying customers. Before automatic brakes, a brakeman could climb out from the caboose and move along the train to inspect problems or apply brakes, and when a train stopped, the flagman walked back along the track with lanterns, flags, and warning devices to prevent collisions with approaching trains. Cabooses were often assigned to a conductor for exclusive use and could serve as living quarters, equipped with a desk, restroom, water supply, stove, heater, bed, and icebox, often personalized with curtains, blinds, and family photographs. With the rise of electronic monitoring systems and computers, the caboose is no longer the traditional end of the train.
