Nicholas, Technical Product Specialist, LEGO® Consumer ServicesThanks so much for the feedback, all of this is excellent information I will be sure to bring to our design team. The great thing about LEGO trains is that you can build the parts you aren't satisfied with! If you are interested in building your own train add ons, feel free to use the part listing in the back of the building manual to order the parts on our bricks and pieces website. Happy Building!
