We are building our lady your Hogwarts express and then we will be converting it to a motorized train! We bought one set of tracks. One box of Lego city train tracks does not make a full circle but they are a start! We will probably have to buy a few more! #lego #legotrain #legoharrypotter #legohogwartsexpress #harrypotter #hogwartsexpresstrain #serendipityfarmsutah #whimsicalcloud
