3281 Trinity 2 Bay Covered Hopper

Prototype Information

Trinity Industries introduced the 3281 covered hopper in the late 1990s to handle heavy, dense commodities like sand, cement, and minerals. The 3,281-cubic-foot car combined a compact frame with high loading efficiency, giving shippers a tough, reliable option for bulk materials. Its welded steel body, gravity outlets, and low-maintenance design made it a favorite in construction and industrial service. Built for performance and longevity, the 3281 quickly earned a reputation as one of Trinity’s most dependable short covered hoppers.
