    HO Scale Trinity 3281 2-Bay Covered Hoppers

    The Trinity 3281 2-Bay Covered Hopper is a specialized freight car designed for transporting bulk materials such as cement, sand, and other dense commodities. Introduced by Trinity Industries in the late 1990s, this hopper features a two-bay design, which allows for efficient loading and unloading through round roof hatches. The smaller size of the 3281 hopper compensates for the greater density of its lading compared to grain, making it an ideal choice for industries requiring the transport of heavier materials.

    The Trinity 3281 is often seen in unit trains moving loads of fracturing sand to new oil fields, cement, bentonite, and other bulk goods. Its robust construction and practical design ensure reliable performance, making it a valuable asset for railroads and shippers alike.
