You're the reason why I spend all the time writing about this... giving me inspiration and thoughts that I haven't had. A lift out... Hmmmmm. It's not too late for that. L-girder is flexible enough to make modifications at this time. I'll look at the structure and see what I can come up with. I have to separate some of joists a bit so it's easier to get up through them. As it was I was able to stand between them if I did so carefully.
Trains have been running but are stymied now by the bridges being out. I was going to plaster the ravines so the bridges could be installed right away and get the trains running, but now I'm glad I've chosen to flesh out the city area since I would have been banging into that plaster all the time. I've bumped the screen wire between the tracks more times than I'd like to admit, but without scenery it doesn't matter.
