“This was supposed to be a reward for my son's summer reading. He was looking forward to building a track for his Lego Hogwarts train. He was disappointed that he couldn't even build a loop out of this set. Bummed me out too! I suppose that's partially my fault for not looking closely at the box, which shows that the loop can only be built with this AND another track set.We love Lego and rarely bat an eye at the high prices, which are usually worth it to us. But to sell the Hogwarts Express kit with no tracks, and then to have buy multiple boxes of this "expansion" kit to make even a simple loop seems like a way to just grub around in a loyal customer's pocket.Conclusion: if you're buying this to have a few extra pieces to go along with track you already have, then great! That's what it is for. If however you're hoping to be able to create even a small track from scratch, this kit alone is not enough.”
