All of our castings
are manufactured in the UK
HPM Steam offers drawings and castings for the 3", 4" and 6" scale McLaren 10nHP Road Locomotive traction engine, and the 4" scale Foster 7nHP Road Locomotive traction engine. Whether you are interested in building one of our engines, or part way through, we can assist in bringing your engine to completion.

We are a small company with enthusiasts at our heart, not only providing the castings for your engine, but also if required, machining facilities for those parts you can't quite fit in to your machine.
