American Limited Models HO 1057 TrinityRail 3281 2-Bay Covered Hopper Norfolk Southern NS #236162 (Gray, Black)
Introduced in the late 1990s, TrinityRail's 3281 cubic foot capacity, 2-bay covered hopper is ideal for handling high-density products such as sand, roofing granules, and cement. Measuring 41'-11" long, these cars are equipped with three or five round loading hatches and a pair of gravity outlets to facilitate off-loading those commodities. Based on similar, larger covered hoppers in the TrinityRail catalog, these cars are distinctive in comparison to older 2-bay covered hopper designs thanks to their overhanging, arched roof profile, heavy top reinforcement chord, and folded jack pads at the bolsters. This design has proven to be popular with shippers and railroads alike, and can be seen traveling singly in manifest trains, in large groups, and even in "unit trains" hauling a single commodity.
