Freelance modellers and scratch builders in HO gauge (16.5mm) use proven Athearn drive components for construction of reliable all wheel drive diesel locomotives. British HO and American On3 models among countless others have been produced using Athearn components. Here is a listing of the principal measurements to assist in selecting the parts for your next project. |
