"When I first saw the Hogwarts Express, I knew I had to have it. A few back order later and it finally arrived. Love the look of the train!
Have to say this set appears to not have been made to be used on a track. The stock version I see better used for a kid to play with on a flat surface rather than a track, or a really good model on a shelf. However, if you are planning to place this on a track like I was, some very small and easy modifications need to be made. I found when the train was turning, the front set of wheels would connect with the second set of larger wheels and would cause a lot of drag. Also the back car's wheel don't turn like the city sets trains, also causing additional drag.
Being in the way I have it on a track, I had to add power functions. I prefer the original PF, and adding PF to the train was not overly hard, although modifications need to be made.
Not sure how LEGO feels about me modifying all 3 cars and posting about it, but its still a great train, great look, and still a good value on the cost."
