Whether called a cabin, waycar or crummy, the Atlas HO Scale Standard-Cupola Caboose is based on steel cars that brought up the markers on trains coast to coast beginning in the 1960s. On these cars the tall cupola allowed crewmembers to see over some of the taller cars in operation in the postwar era. Each Standard-Cupola Caboose features an injection-molded body, fine end railings, applied details and roofwalk as appropriate, accurate decoration, roller-bearing caboose trucks, metal wheels and all-metal magnetic knuckle couplers. Standard-Cupola Cabooses were common sights on railroads from the late 1960s to the 1980s and some are still in use as "shoving platforms" for long switching and backup moves in 2020.
