Athearn Genesis HO GEN F89-F Flat Car WTTX Twin 45

HO Scale Flat Car, WTTX "Twin 45"

This HO scale flat car is a fitting companion to the model train locomotives in our collection. It recreates the Trailer Train (now TTX Company) F89-F flatcar, a design introduced in the early 1960s that remained a fixture of North American railroading for decades. The car arrives fully assembled and decorated, ready for your layout.

Prototype Background

Built at Bethlehem Steel's Johnstown, Pennsylvania plant, more than 9,000 of these 89-foot, 8-inch (over strikers) cars were produced throughout the 1960s. Their C-channel side sills set them apart from other long flatcars of their era.

Over the years, these cars were adapted for trailer-on-flatcar service, autoracks, structural steel, and more. Many were later reassigned to new roles, including vehicle loading and pipe service.

Model Highlights

This model was developed from field measurements and builder diagrams to capture many prototype details and variations, so it suits modelers working in a range of eras. The WTTX "Twin 45" configuration is modeled accurately, with its hitches set to match the prototype.
