Apples55, I like your layout. I like that it is open and you can reach all areas of the layout. I plan on using 072 GarGraves curves so that everything made will run OK and look good. I want to have a separate track line for my 1953 Lionel 736 Berkshire to run with Madison passenger cars, and then another track line for my Lionel Legacy locomotives.
Thanks. I used Mianne’s 30” wide version which made access to any part of the layout relatively easy (the center island engine yard is 48” wide, but is accessible from either side. Of course, as is typical with me, I added a 24” freight yard on one side of the layout which makes accessing one area a bit of a stretch - literally!!! I used O-72 and O-84 curves, so hopefully, there is nothing I can’t run even if some of the 21” cars do look a bit odd on the O-72 lines.
