Roundhouse Train Parts

Shop Roundhouse spare train parts and replacement components to help repair, maintain, and restore locomotives and rolling stock. Many Roundhouse HO Scale spare parts in this selection are intended for HO Scale Roundhouse models, including older equipment that may no longer have readily available factory support.

Trainz obtained Roundhouse parts inventory before the brand was sold to Athearn. That earlier supply helps make replacement components a distinctive part of our Roundhouse offerings today. Availability varies by individual part and model, so compare listings carefully before ordering.

Roundhouse, associated with Model Die Casting (MDC), became known for HO Scale model railroad kits, locomotives, and rolling stock. Athearn later acquired the Roundhouse brand. For collectors and modelers maintaining older Roundhouse equipment, Roundhouse spare parts remain useful because different production runs and kit versions may not share identical components.

Trainz's acquisition of Roundhouse parts stock before that brand sale is especially relevant for customers searching for original Roundhouse spare parts to maintain older models. Always use the individual product listing, rather than brand name alone, to assess fit.
