    Awesome looking train

    I would recommend this to a friend!
    Purchased for: Self
    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.

    Disappointing part choices
    | 25-34
    Purchased for: Self
    While I can't say much about the app, what I can say is the choice of parts is disappointing. The old train axles are gone :( The new train wheels are very resistant, lots of friction when used with a motor. :( There's only one magnet coupler, yet several of these new ones which are fiddly and awkward to use :( Disappointed LEGO, very disappointed, The lack of trains made my lego is bad enough, but now if newer trains have these new wheels and axle-less wheels then it'll be very poor for the train fans.

    Thank you for your review, and I'm sorry to hear that you were disappointed in this set. Unlike some LEGO® trains, the Ghost Train Express wasn't designed with motors or motion in mind. We definitely recommend exploring the features of the app as well to bring out the exciting 'Hidden Side' of this train! If there's anything we can help with, feel free to reach out at

    It's fun but...

    Purchased for: Daughter
    It's a fun but there are deficiencies. 1. Only comes with 1 magnetic coupler so it's not really compatible with our other Lego trains. 2. When motorized, engine is fairly tipsy in turns 3. Engine construction is a bit too flimsy for regular wing deployment. (The kids break it easily) I would not recommend if you are a train veteran looking for train parts.

    Hey there, thanks for your review! While this set can be motorized or combined with other trains using some ingenuity, it's primarily designed as a standalone playset, complemented by the LEGO® Hidden Side™ app experience. If you're interested in building motorized trains, we'd recommend one of our other train sets, like 60197, 60198, or 71044. Happy building!

    Purchased for: Son
    Do not buy until you make sure your devices are compatible. We took our son to the Lego Store in Downtown Disney in Anaheim Ca for him to spend his birthday and to purchase a new Lego set. The employees were showing a demonstration of this product. My son was super excited to buy it and play online with it. We live 3 and 1/2 hours away from the store we purchased it at. When we got home we were extremely disappointed to find out that NONE of our phones or tablets would work with the online content. So now we have a heart broken son who was looking forward to discovering the online content only to be disappointed and heart broken.

    We're sad to see your son's heartbroken. We'd never want him to feel that way. We should keep in mind that the LEGO® brick remains at the heart of the play experience. For the online game to work, you'll need a device that supports AR Core technology. Please check our device guide at for an updated list. Hope this helps!
