Saw and bought this Miniature train set for £1.99 this lunch time at the Blackpool store. Its in a retro packaging. with three pull along container cars. Train engine is approx. 10cm long. battery operated. obviously comes with track etc. there was an even bigger set for £7.
May be a good treat for a budding train enthusiast, if such a thing still exist.
I got one as a little extra for my daughters birthday.
