After being in the house 18 months, finally got the train room cleaned out. 3 days later I have some of the bench work built. Still have to add a 12x12 island in the middle. There will be a lift up to enter the walkways. The walkways will be 3 feet wide and go around where the existing bench work it. Hope to finish the rest of the bench work next weekend. The room is 26x19, under our attached garage.
