This ready-to-run N Scale 52'6" Greenville 2494 Mill Gondola was introduced in the early 1980s to a new design developed by Trailer-Train/TTX's R&D department. The cars were 2,494 cubic feet in capacity and built to be heavy-duty and long lasting, carrying steel ingots, scrap steel and coiled steel. Trailer Train employed several manufacturers to build the nearly 4,000 GONX cars, including Greenville, Thrall, Pullman-Standard, and others. The ready-to-run car features a detailed, injection-molded styrene body, fine decoration, free-rolling Delrin(R) trucks with contoured axles, Magne-Matic(R) magnetic knuckle couplers and proper weight.
