I have the Melrose Park station. After about a week the power board failed. I wasn’t upset about that because, like all Menard’s buildings, it looks like Chevy Chase’s house in Christmas vacation. When I got it on my bench, like Steve, I was impressed by the amount of glue the factory used. Like the glue holding it together, they use a 1/2 pound of hot glue to “secure” the lighting board. Using a hair dryer and a knife I finally got it out through the hole in the bottom.
Instead of cutting into the back of the building, you might be better off cutting out the floor. I wouldn’t attack it with a dermal unless you are sure there are no wires in the way. While nice buildings, their construction makes them difficult candidates for much customization.
