Paul, I am sorry you had to dismantle part of your layout, but maybe your experience will help someone else who is thinking of building a layout and will keep access in mind. It is an easy mistake to make, and while I haven’t done that, readers of my posts over the years will recall other mistakes I have made. That is one of the values of this forum, tell others what worked for us but also what didn’t work. I hope you will come up with an even better design for your rebuild!!
