Cindy: Didn't try to do Pem Junction - too long. It is slow progress because of work. However, I have collected an array of decent locos and my track plans are virtually complete.
I would love to try DIGI, but my rolling stock would have to be modified. I'm going to spend more time up there (the loft) late summer after my daughter's wedding.
My theme will be early to mid sixties, but I have a Princess class that needs a paint job and a new BR number, so still a long way to go before I can add some realism.
