Historically, the caboose was used on the ends of freight trains as both the office and quarters for the conductor and brakemen. They contained a desk for paperwork, bunks for overnight, and a stove for cooking and heating, among other basic amenities. These cars also usually featured a cupola on the roof, where the crew would ride to check for hotboxes, abnormal car movement, or any other items seen as potentially hazardous. In use up until the 1980s, computerized end of train devices saw them largely phased out. Today only a handful of cabooses survive, mostly on shortlines and in museums.
