This detailed, ready-to-run Atlas Master(R) N Scale 50′ General American RBL Plug-Door Boxcar (RBL is the AAR class for an insulated bunkerless refrigerator car with loading devices) is based on cars designed in the early 1960s. Revolutionary for its all-welded body construction, it offered a wide variety of load restraining devices available to customers. These cars were designed for transporting goods that needed to be shielded from extreme temperature variations. While initially used to transport canned goods and newsprint, the cars became very popular for shipping beverages and perishables. While not providing actual refrigeration, a refrigerated load could expect to hold its temperature within a few degrees for several days in transit. This Atlas model features etched-metal roofwalks, appropriate 100-ton trucks with metal wheels, body-mounted couplers and accurate decoration. The 50′ General American RBL Plug-Door Boxcar is one of many Atlas and Trainman N Scale hopper cars.
