7 1/4 tram locomotive

I was given a 10 1/4 tram in summer, it was originally from Aston Tramway Museum. Its wiring is in a bad condition as it is so old. It's a gauge of 10 1/4 at this moment in time but all in good time it will become a gauge of 7 1/4. This will then live at Echills Wood Railway at Kingsbury water park.
