I am working on designing a merged layout of the Granite Gorge and another layout, Tyco Extender (mid 1970s). Both of these layouts I had some years ago, and they were both torn down for different reasons. At this point, I have a SCARM design of the merged layouts, and an additional yard area. I have been working out the bench work with a woodworking design program. The table will end up in 6 sections. After reading this thread, I will likely build in 3 paired folding sections (2 5x10, and a 4x8). The 4x8 will have a siding yard, while the 5x10 parts will have the granite northern, and a Tyco expanded layout. They appear to interconnect well. While it is likely I will not be able to start building the layout until December or January, after my move to a larger area. I have an empty room, I have my eyes on, any may need to renovate a little. The wife hasn't figured out the size, but I suspect the grand kiddies will like it. I suspect I will be borrowing a couple of ideas from this site... Any suggestions would be helpful....
