This is a small layout that I built and exhibited with my, then, 11 year old son, Adam, about 20 years ago around the Norfolk and Suffolk area. It had live overhead collection with cuts in the track which allowed automatic running, stopping and starting for 3 trams in each direction. All the trams were 4 wheelers powered by BEC trucks.
I think its biggest attraction was that it was mainly operated by Adam and we encouraged children to come and have a go driving a tram.
