Man, this thread just opened up a giant can of worms for me. I always played with transformers and legos when I was a kid. Thinking about getting into the lego trainsets now. Would be cool to have a giant network of holiday trains going under the xmas tree during the holidays.

 

I wish I had the money to do a Lego train setup myself. For the past few years I've also been wanting to get one for under the tree, just never have quite that much money to spend on one.
