Wind-Up Train BookA toy and a book in one, this large, chunky board book comes with a wind up toy steam train and four slot together tracks. Children can wind up the train and place it on the tracks to see it chugging through the city, over mountains and alongside rivers until it reaches the train museum. The tracks can be used embedded in the pages of the book or slotted together to make one giant train track. A fantastic gift for young train enthusiasts. Age: 3 to 5
