Hi,
I have found what appears to be a mixture of 4.5v and 12v track and trains in a box. It appears to contain the 7740 electric inter-city train set, but it is incomplete. There are also some battery wagons which I think are 4.5v, but do correct me if this is wrong. The track is grey and there are electrical contacts which run along the middle. There is a crossover which I think must be quite rare as I cannot find anything about them on the internet, as well as signals and point motors. Is this type of railway considered collectable yet and is any of it at all rare?
Thanks, Rupert
