OK, this is my very crude trackplan.
Nowadays everybody use CAD software but I used CARD(-board) technology.
With my elegantly ugly hand writing, the plan almost looks like the ancient writing in a cave.
Anyway, existing Closet yard will be connected to top side of extension to the left.
Red line is the main track.
If you see it closely, there is a gap between tangents and curves. That's where "easement" will be.
I used this easement method on my existing layout and worked quite well. Especially for forbidden tight curves which I have them everywhere.
Bottom left is for the future extension. (Yes, I'm still going!...maybe.)
I have a only 1'x3' extension space and I tried not squeeze the tracks but it is still "too busy" looking.
To convey the atmosphere of Los Angeles trackage, probably I need to eliminate some tracks.
Also I need to think about what kind of car I can spot on the industry trackage.
Ideally I would like to have spots for a gondola, a boxcar and a centerbeam car.
Will see how I can do this.
Different view angle of my CARD technology trackplan.
Any suggestions are welcome.(in other words, please help me!!)
