I would love to see different color trains and different train (skins?) designs available. I'm using the American Arrow train for my Demon coaster... but a Demon train looks a little silly with stars and strips. The ability to change the text on the train front would be nice too.
"Demon would look better with a red train, an orange, a yellow and one black."
