HO GEN F89-F Flat Car WTTX Twin 45 (ATHG-2244)

This HO-scale Genesis F89-F flat car with WTTX Twin 45 trailers recreates the iconic intermodal car used by Trailer Train and its successors from the 1960s onward. It’s a ready-to-run model that features the distinctive C-channel side sills and is configured to carry two 45-foot trailers in the WTTX setup, with raised and lowered hitches to mirror different trailer lengths. Decorated and ready to roll, it’s designed for authentic intermodal scenes on modern HO layouts.

Key details support reliable operation: a heavy die-cast underframe and 70-ton roller bearing trucks with spinning bearing caps, machined metal wheels with RP25 profiles, and body-mounted scale knuckle couplers for smooth coupling in dense trains. The model is weighted for stable handling and includes wire-formed brake plumbing and a detailed deck. Minimum curve radius is 22 inches (24 inches or larger recommended), and it’s designed to blend with Athearn’s trailers and containers for versatile, era-spanning intermodal layouts.
