HO 57' Trinity Spine Car BNSF #300581 Model (ATH41102)

HO-scale Trinity Spine Car in BNSF livery. This 57-foot model reproduces a Trinity-built spine car designed to haul 40-foot trailers and containers on modern HO layouts. Based on the late-1990s TTX Company RAF30A class—a 70-ton design—the model captures its proportions and detailing for an authentic on-rail presence.

Key features include a precision die-cast spine, separately applied brake piping, fine ladder detail, and McHenry scale knuckle spring couplers already installed. It rides on 33-inch nickel-silver wheels with RP25 contours for smooth operation on most HO tracks, and trailer hitches come separately in raised and collapsed configurations so trailers and containers can be attached to suit the scene. Etched metal walkways add realism, and the model is weighted for stable running with a minimum radius of 20 inches. Athearn’s 40-foot trailers and containers are ideal loads for these cars, expanding intermodal possibilities on an HO layout.
