Those marks may come out, but I'm not sue and didn't want to clean too aggressively and mar the finish. This set is primarily metal with some plastic detail parts.
In the box is the engineer figure, manual and parts bag. I read on-line that this engine is equipped with the older decoder that only works with the 6030 controller and not the newer 6021 controller that utilizes the new Motorola format.
