Looks like you beat me to the submit button. I don’t see how I could make the point motors operate through 100mm of anything to be honest. I also really want to be able to secure wiring, etc under the board with screws. I’ll be using foam on the top for a variety of reasons - mostly to be able to give the landscape some depth below the rail level - something that is missing from a lot of layouts.
Also not sure how I’d make that style of board easy to move/disconnect/reconnect when being moved (It will be so this is an important factor, I can’t build it into the room permanently)
