I finally completed the Animal Train I had intended to make two weeks ago. I got this idea from The Princess and the Tot, and the idea is originally from First Palette. My girl loved this train...but it was off the wall and torn in pieces within 15 minutes. :) She still plays with the animals, and I plan to repair the train. One thing I learned was that it would be helpful to mount the train to a background rather than directly to the wall. That would make it more difficult to destroy, and it would also make it easier to get the animals into the cars.
