HO F89F Bi-Level Auto Rack Southern Railway TTBX #930244 (ATHG-1780)

An HO-scale F89F Bi-Level Auto Rack in Southern Railway’s TTBX scheme, this model recreates a two-level auto carrier designed to haul automobiles on intercity routes. It’s a highly detailed piece that adds prototypical realism and presence to an HO layout, with accurate proportions and authentic livery to match the look of the real-world equipment.

The model combines a die-cast underframe with a highly detailed injection-molded body, featuring wire-formed brake plumbing and machined wheels with RP25 contours for smooth operation on a wide range of tracks. It uses body-mounted scale double-shelf knuckle couplers, 70-ton roller bearing trucks with rotating bearing caps, and era-appropriate details such as a detailed deck, ride height, and authentic safety railing, plus hand brakes, cut levers, and trainline hoses. End bridge plates are included for installation where applicable, and the layout radius should be 22 inches or larger for optimal clearance (24 inches or more is recommended).
