This main line caboose was built by the railroad at DeSota, MO. and its interior was finished at Sedalia, MO. A total of 350 were built from 1977 to 1981 as the last caboose built for the Missouri Pacific railroad. The bay windows that extend out from each side are the lookouts used by the crew to keep watch on the train. This served the same purpose as the cupola on top of other cabeese ( coined by American Railway Caboose Historical Educational Society, Inc.). A single level floor plan was also considered to be safer and easier to heat in the winter. It gave the crew an excellent side view, especially going around curves. The seats at the bay windows can be reversed and have seat belts to prevent injuries. It is often confuses with a short haul transfer caboose due to being based on that design with a smaller cabin and larger platforms. The overall length of the car is 41 feet 7¼ inches and the cabin is 17 feet 10 1/8 inches long. Its empty weight is 51,900 pounds. The Union Pacific donated the car to the museum in 2000.
