HO ATH 85' TOFC Flat Car SOO #5590 (ATH-1553)

HO scale 85-foot Trailer-On-Flat-Car (TOFC) in Soo Line livery, numbered 5590, designed to carry two 40-foot trailers on intermodal runs. This model is fully assembled and ready to run, capturing the look and function of mid-century intermodal equipment introduced in the 1960s to pair highway trailers with rail transport.

Details include factory-installed wire grab irons, detailed trailer hitches, and a metal underframe to maintain correct rail height and smooth operation. It rides on machined RP25 profile 33-inch metal wheels and uses swing-mount coupler boxes with McHenry scale knuckle spring couplers installed for reliable, prototypical coupling. A minimum radius of 22 inches keeps operation smooth on a wide range of HO curves, reflecting the era when intermodal service standardized two trailers per flatcar.
