Actually I had thought about Doing the whole roof over and walk under…but that will require a major expenditure in materials. It would be nice to have a Shop Annex for storing stuff thats not on the back porch…so mebbe at some point down the road.
The ‘Switch to nowhere’ is planned for a locomotive loading point in the future…I’ll install a plank where a loco tote can be set down to run locos on and off the layout without picking them up. Not a high priority since all my locos live on the layout currently, but or visitors…and eventual traveling. I also forsee installing a removable turntable like yours, if I ever progress to the point that I have turning facilities at the far end of the line…
The drawing’s not to scale…the longest track is almost 12 feet long so its prolly got a capacity of almost 8-9 cars…I’ll know more as I get more rolling stock built! I like the idea of just covering the inside two and leaving the third one as an active fiddle!
