Full disclosure: I love all things Harry Potter. My wife and I read the books to each other as they came out. We couldn't wait for each new volume, and when the movies came out, we would read the books again. So I was especially excited when Peggy and Dick Mavis donated their authentic model of the Hogwart's Express to our Youth Services department. It's on display in the juvenile area of the second floor, and yes, the transformer is hooked up and it actually runs! Our deep gratitude to the Mavises for their generosity. You really have to come and see this train. It's the neatest thing since Butterbeer.
