Mine lifts up too, like the prototype. If you turn a secret 2x2 round lump of coal in the top of the tender internal gearing will lift the rear set of wheels off the track. Unfortunately, this engine is still too long for most Lego engine turn tables. The rear wheel set actually moves in 4 directions - up, down, left and right. The three sets ahead of it are linked solidly, but that is the longest set of linked wheels you can do on Lego track. So the final set must be able to move left and right independently of the first 3 so the tender can navigate corners.
