So, latest revision, I took out the green line....it was just in the way and going nowhere. Amazing how this thing has evolved. Very little like the original....I have added some notes that i hope will help and not clutter. I know it is hard to differentiate colors.
As far as exact curves etc. I think i am real close to everything fitting ....if I have to tweak the radius a bit I have some flexibility to do that.
I can pull in long passenger trains into the city station or going other way into the small town station - I can have 2 or 3 trains queued up to go either way the blue elevated line between will help separate as if they are 2 separate places but actually share track
I think I am real close now....what do you think?
