I'm on the mailing list for the KC Visitor's Center, and unfortunately I just recycled the small holiday mailer I received. From what I remember, there is some type of holiday trains display set up at Union Station, and there is a holiday train set up at Crown Center, but the emphasis on the Crown Center display is on the gingerbread buildings, and some trains run through the layout. There is also the full size Holiday Express Train that KCS operates. It spends a few days at Union Station. I haven't seen any of them in person. Kansas City seems to have some nice holiday traditions. I'd like to see Country Club Plaza decorated for the holidays.
