The chassis could be shortened a bit, but I would prefer to use something that isn't as high. Lowering the body onto the blocks would look horrible internally. Ideally an old stlye IP engineering chassis would be perfect for this. The powered Playmobil Chassis will become a GVT Loco (watch this space) the other is unpowered. I am also planning some scratch build wooden coaches on Playmobil running gear which will go with my repainted Playmobil loco.
