    All LEGO trains should be built with motorization

    Just some constructive criticism from a fan. I noticed LEGO responded to some reviewers about this train not being intended for motorization. In my opinion, all LEGO trains should be motorized or at least designed to be easily converted for motors, especially since you already sell other motorized trains and track. It would definitely be more consistent. It is confusing and disappointing to have some trains with motors and some without. Why wouldn't you want to maximize the compatibility and play value of your "cool" train sets? It can't be that difficult to make a few mods to the build to allow for the convenience of a motor in the trains. Just a thought from a train collector and LEGO fan. Even better would be to provide a simple motor upgrade package that one can order when the train is released or just include the motor. If you are trying to reach a price point then I understand not including the motor but at least make it easy to upgrade for those of us that would want it. It means happy customers and more sales for LEGO.

    Awesome looking train

    I agree with the previous reviewer in that the new train wheels without metal axle are quite rubbish. I think their advantage is simply that they are much easier for younger kids to put together. But then the new couplers (non-magnetic) are a fiddle so that negates the above. Otherwise, this set is quite fun. It looks awesome in my opinion and provides a decent amount of playability. Pretty straight-forward to build so will suit a diverse range of builders. I love trains so this had to be added to my collection, but I should warn that it requires quite a big mod to motorise it. This was also the first of the hidden side sets that i have built and so far I like the theme. The overall feel of the theme is well designed and the characters are fantastic. The augmented reality app is pretty cool, and although it became boring for me quite quickly I think it would entertain a younger audience well.

    This lego is great value for money and i recommend it for the ages 8 to 16. The app works well with my device but it may not for everyone. The feature that make it spooky are super cool so you can have a demon train. I bought extra tracks for it and it fits on them. I havent tried to power it but i may in future. Great set, Highly Highly recommend as a birthday present or christmas present.
