I have what was represented to be a new #62995 (and it did arrive with all the documents in the standard display box in apparent new condition). I have found on other forums comments about the white plastic gears cracking and I suspect the gear design to be the explanation of the very noisy operation. What, if anything, is the resolution for this problem ?

I have N Scale structures (buildings) in display boxes that are glued to the bottom of box. What is the best way to remove the cardboard "platform" the structure was glued to (and why were they glued to the box)?
