On "The Toy Store", go to the space room. You will see a rocket ship with a crate and bones on top of it. There will be a trampoline near by. Jump on it to get on the rocket ship. Once on the rocket ship, you will see the trampoline that will get you to the train. You do not have to use the large trampoline to get to the train at first. Get on the rocket ship and jump towards the largest trampoline. This is the most fun way of getting to the train.
