The MOC features sliding doors and a fake tail light. You can attach it at the other end as well or even add a second one.
In addition, the wagon contains a battery box that you can use to power an engine. The instructions show how to attach an extension wire, but you can also attach e.g. the input wires of the IR receiver instead. The power can be switched on and off by pressing on the air grille on top of the roof.
