One of the most common of all flat cars, GSC "Commonwealth" 54' Flat Cars have been in service since the 50s. Built around a large one-piece steel casting, the prototypes could handle a wide range of cargo and were often rebuilt for piggyback loading. In later years, they were fitted with bulkheads and handled loads such as lumber and pipe, and some lines added portable bunks for handling logs. These revised Walthers N Scale freight cars feature finer detailing, paint, graphics and come equipped with Accumate® magnetic knuckle couplers. Each includes a clear plastic case that's ideal for storage and transport. The cars come equipped with bulkheads as appropriate for each roadname and they're available individually and in limited-run two-packs for a total of three roadnumbers per roadname.
