HO 57' Trinity Spine Car BNSF #300557 (ATH41100)

HO-scale Trinity 57-foot Spine Car in BNSF markings, a detailed model built to reproduce Trinity-built intermodal cars used to haul trailers and containers. Based on late-1990s RAF30A prototypes operated by TTX, this faithful replica lets modelers load a variety of trailers and containers on the 57-foot spine.

Features include a precision die-cast spine, separately applied brake piping, fine ladder detail, McHenry scale knuckle spring couplers, and 33-inch nickel-silver wheels with RP25 contours for smooth operation on common HO track. Trailer hitches come in raised and collapsed configurations to suit different loads, and etched metal walkways add to the scale realism. The model is weighted for stable running and designed for a minimum radius of 20 inches, making it a practical addition to intermodal scenes while faithfully capturing the late-1990s spine car look.
