On the right in the sketch, I will be adding a 2nd level to my layout to mimic New York City in the 1940s.
How high above the existing layout should the 2nd level be so I can access trains and track below it?
My current layout surface is flat and 40" above the floor. The benches are 3 feet wide. I am 5'-6" tall. Access is from inside the layout only as the right side of my layout is against a foundation wall.
If I make the 2nd level 12" above the current layout, access to the 1st level could be inadequate to maintain tracks on the 1st level.
My thinking is the 2nd level should be 16" above the current layout.
In any case, I will need a platform to elevate me so I can maintain the 2nd level.
Your thoughts?
