This LEGO® Powered Up narrow gauge style blue train engine uses the smallest footprint possible. It includes the bluetooth hub into the body of the train while leaving room for a fully designed cab interior that fits one mini-figure. The front of the train is removable so the batteries can easily be changed. Additionally a custom removable section sits over the power button so that the hub can be powered up without removing it.
