This model is built to operate in the same way that the mechanical steam engine operates. Spinning gears, pistons and wheels carry the body and soul of 19th century engineering, when locomotives represented the mainstream of technical progress.
Using the massive gearwheel array, this relatively large model can run up to a distance of 5 meters. The distance and speed depend on the winding of the large 12 rubber band engine. The engine is started with a lever near the driver’s window.
The locomotive main mechanism operates as close to the real thing as possible with asynchronously operating piston and valve. They’re clearly visible inside the model, allowing a spectator to see how steam would get into the Locomotive’s steam chamber. The little doors and roof hatch let you take a look inside the Locomotive’s cabin, complete with an instrument panel and a retractable ladder beneath the door.

Notes from Alex:
This was one of the two most challenging models to assemble (the other being the horse). Although true with most Ugears kits, it is vitally important that all gears rotate freely and mesh without sticking or hesitation. Special effort should be made to sand down all the points on the gears where they were attached to the plywood sheets. Any point of friction will prevent the model from operating correctly.
I found that for this kit, graphite powder worked a bit better than wax for lubrication. However, it can be difficult to apply neatly and will stain the wood - but since it's a Steampunk train, a little grime just adds to the authenticity!
Because I knew this was going to be used for demos, and therefore run quite often, I replaced the twelve rubber bands that power the engine with six heavier ones. It is possible to do this once the model has been completely assembled, but it's not easy.
There are some small touches that are easy to miss in photos - the top doors on the tender can be opened with a lever on the side, there is a small retractable ladder on the side of the train cab, and there are opening doors on both the train and the tender.
