Real Train Database

Real-world prototypes that inspired HO scale models

Every HO scale model is based on a real-world prototype — the actual locomotive or railcar that inspired its design. Understanding the prototype helps modelers choose accurate paint schemes, match equipment to the correct era, and build realistic consists. An EMD SD40-2 in BNSF heritage paint, for instance, tells a different story than one in original Burlington Northern green.

The TrainDex prototype database covers hundreds of diesel locomotive families (EMD, GE, Alco, and others), freight car types (boxcars, covered hoppers, tank cars, gondolas, and well cars), and passenger equipment (Budd streamliners, Pullman heavyweights, Amtrak Superliners). Each entry includes builder history, production dates, technical specifications, operating railroads, and a cross-reference to every HO scale model available from tracked manufacturers.
