When I was a little girl, laying on my stomach and watching the family Christmas train go round and round our Christmas tree was a favorite pastime that could keep me busy for hours. And while still a complete sucker for a classic train set, I have to admit this Lionel Harry Potter Hogwarts Express LionChief Ready to Run Train ($338) might just call for a new holiday tradition. This Bluetooth-operated Hogwarts Express comes with a locomotive, two passenger coaches, a combination car, and tracks, of course. Another few perks for the kiddos? The passenger cars light up, and the trains make chugging and whistling noises. Read through to get a look at this magical train set, and try not to picture it sitting under your tree this year.
