Willy Tyler has the coolest train set-up ever. It takes up half of Willy’s attic and encompasses everything from medieval times to the Wild West. Willy and his cousin, Zack, spend countless hours playing with the Tiny Town Express and rearranging the model towns and the toy figurines. But when Tiny Town starts rearranging itself, Willy and Zack learn much too late that the toy figurines are alive, and they’re trying to take over far more than Tiny Town.
