This easy-to-assemble Accurail 50' Steel Boxcar w/8' Superior Doors, No Roofwalk & Low Ladders kit is based on widely used 50' boxcars. New safety rules beginning in the 1960s required the removal of roofwalks on boxcars, and in the process ladders and brakewheels were also lowered. The car features a one-piece detailed injection-molded plastic body with most details molded in place for durability during operation. Other features include realistic decoration with end reporting marks (on decorated models), underbody details, trucks with Delrin wheelsets, nonmagnetic axles and AccuMate(R) magnetic knuckle couplers. This steel diesel-era boxcar kit is great for modelers of all skill levels and includes complete instructions.
