What is it about children and trains?

Just an observation, but I just find it amazing the fascination that muggle, and magical children alike have with Trains. There's something magical and fascinating about how different they are, how they operate, and the places that they'll take you! So do to this fascination, needless to say, we had a wonderful time today, and the kids really enjoyed seeing Thomas, riding the train, and just seeing things through childrens eyes.
