Peter's Railway Grandpa Goes Bananas - Christopher G. C. Vine

A railway adventure in a transport museum. The children spend the night at a railway museum where they all agree that it's a great shame that nothing works: The exhibits are all lifeless. That is until Grandpa has one of his "excellent" ideas! Why not bring one of the monster locomotives back to life? Just for one day, the museum is filled with smoke, steam and noise...and policemen!
