In this build series Dan creates a freelanced Nn3 narrow gauge 2-6-0 steam locomotive. While this model train doesn't follow a specific prototype, it is meant to look typical of old time narrow gauge steam motive power.

This engine is designed for a small N scale layout, so a short wheelbase, the ability to negotiate tight curves, and working couplers on both ends are major design goals. This locomotive has to be able to perform freight, passenger, and switching duties.

The finished model will have DCC control and LED lights.

Like many other Nn3 steam locomotives, this model train is designed around a Marklin Z scale 2-6-0 mechanism.

In this episode, Dan fits a 3D printed cab to the locomotive. He continues work on the boiler, narrowing the walkways to match the cab and replacing the steam dome and smoke stack.

Dan also prepares new headlight castings to make them light-able and plans the wiring for the front headlight.

Though the design is freelanced, Dan's goal is to create a locomotive that is reminiscent of steam engines used by the Pacific Coast railway.

Even if you're not an N scaler, or not into Nn3 narrow gauge, Dan's techniques can apply to other models. Be sure to check this series out!
