The Train now arriving...........

While Grandpa painted the bedroom, MaggieD, Ali, Euan & Eve went off for some retail therapy in Stirling. After that (and lunch out), they stopped off at a local level crossing to watch for passing trains.
Accordingly, when they all arrived, out came the trains and a multi-track layout quickly ensued. What is he going to be like when he is old enough for a "proper" train set??
