The most detailed diesel locomotives ever produced in O Scale.

Current project  –  SD45 and related locomotives    

Upcoming project  –  SD40-2 and related locomotives

Please check out our “Future Projects” tab for more information.

These models will be built to satisfy even the most discerning O Scaler. Careful attention to every detail, the smoothest, most powerful drive system available and a prototypical constant lighting system that will revolutionize the way locomotive lighting should be done into the future.

Locomotives will be built to the reservations received. We will be offering all versions of the SD45 with the below list of details. Pictures and additional information will be posted as they become available.

We will be offering these road names, listed here by model (see prototype pictures of these paint schemes under the “models” section in the menu bar above):

Below is the final list of locomotive types and road names. As of 10/26/15, certain models and road names will be increasingly limited in availability or unavailable as the process moves closer to production. Any road name listed in yellow on the below list means it has already been subject to limited further availability or closed to any further reservations. Please check the page of the road names in yellow below for further details. Further information will follow as it becomes available. Models may also become unavailable without notice and this may occur at any time. We will try to keep this updated as time permits. Please email with any questions.
