Exploded Parts Diagrams

Welcome to our free Interactive Exploded Model Train Parts Diagrams

Perfect for troubleshooting and repairs, these diagrams offer a detailed look at the inner workings of various train models. Discover the arrangement of parts, identify specific components, and gain a deeper understanding of how your model train operates.

We're building the most extensive exploded view parts diagram library the world has ever seen. Trainz is developing this to make it easy to identify the model train parts you need and buy them with just a couple clicks.

We have over 30,000 model train parts available, with many you can only find at Trainz. We have over 420 exploded view diagrams to help you select what you need, including never before seen diagrams for the 44 and 45 missile cars, the 44 tonners, the 55 Tie-Jector, and the 2046 Hudson. We will be adding diagrams for Lionel Standard Gauge, Prewar, Postwar, MPC and Modern Era trains in the near future.
