I went back to the sweet shop today and ventured in. As well as the Thomas I the windows they had another Thomas with coaches running round a track. In addition there was also a James on another track and a percy on the shelf, neither running. Apparently James is not such a reliable runner so he has the nickname BR (British Rail), so he was static at the moment.

Happily collecting things all my life...
