So... if there was a 3.5 stars, I probably would have selected that score for my overall rating.I'm still trying to determine how I feel about this LEGO train set, so I may revisit this review in the future after I've had more time to use and evaluate the overall set.A few positives to get this review started:- It's a LEGO train... which means you're all but guaranteed to have fun and the young bricker in your house will love it. I mean, seriously, how can you go wrong with a LEGO train that functions and operates?- The train itself looks great... the dark blue coloring with yellow really pops and is a significant improvement over the previous passenger train.- The new train system has two different options for operation... you can operate the train with the remote that comes with the set, or you can download the 'Powered Up' app by LEGO for free to control the train via your mobile device. When you download the app and operate the train via your phone/device, you get a series of sounds that you can use via your phone's speakers while operating the train. The process of downloading the app and connecting the train via bluetooth to your phone/device was fairly easy and didn't take much time.- The new 'Powered Up' app leaves a lot of growth potential for the future and I can only imagine what LEGO comes up with for increased playability and functionality in the future.A few areas of consideration:- The cost for a set this size is a touch high in my opinion... there are lots of larger LEGO pieces and train functions which command a higher price, but the amount of track you receive and the overall piece count are on the lower end.- The detail on the inside of the train (in all three sections) is rather limited and underwhelming. Sure, if more would have been included, the price may have gone even higher, but be forewarned, there's not a lot happening on the inside.- The amount of track gives you a basic circle... once again, I know it would probably increase the price, but more track would have been a nice touch.- The new bluetooth system for controlling the train is much different than previous systems for train operation. If you are accustomed to using the previous system, you'll find the new system much different and thus far, I would say more cumbersome and less user-friendly. The remote control feature takes a few seconds to actually connect to the train before use. Batteries... you'll need 10 AAA batteries to get this train going (better start stocking up on batteries now).- The 'Powered Up' app seems to work well, but I'm somewhat disappointed in how quickly it loses the connection if you stop using the train for a few minutes. I'm also concerned that the speed of the train seems to function differently from the app on your phone/device than it does via the remote control. This may be something I'm doing incorrectly on my end, but there seems to be something off. The sound functions that are available via the app are a great addition and without a doubt increase the level of fun and playability with this set. I can only hope there will be added features in the future as LEGO expands the possibilities via the Powered Up app.- The small train station is really underwhelming and adds a small amount of additional playability.Overall, I like this set, but I'm still on the fence with exactly how much I like this set. It's good, but it's not amazing. Now, perhaps after more use I will come around and my enthusiasm toward the set will increase, but right now, I have a slight hesitation and skepticism.Would I make this purchase again... yes, however, I'd probably look for a reduced price and I would measure my excitement if I'm familiar with the previous LEGO train systems. If this is your first LEGO train set, then I have no doubt you'll be pleased and excited.Hopefully you found this review helpful. If so, please let me know below.
