Looks like a fun build and it’s Disney themed too! I built the current Passenger Train set with the PowerUP system earlier this year, during a bout of O Gauge withdrawal. 
Enjoyable half day building and the train actually runs well. The set I bought has a handheld remote and works with the mobile app. Biggest disappointment for me was the use of “stickers” for all the train graphics. I was expecting the graphics to be permanently stamped on the bricks, like LEGO does for the people figures.
Looked up the MSRP for this set, $329.
