To start things off, here is a initial plan prepared by myself.
This plan does not show the staging yards, but one can imagine. It does meet a lot of Mark’s goals, it has all his stations, with only one needing modification. It has the stations in their original order, with only Graytown reversed.
It does include the mine branch that head over the pier back to the lower level’s staging. This means a train has to come out of staging, head throughg Costerfield, into Greytown, and run around then head up the branch. Then you get the reverse move.
I have used that reverse loop in the main room in a odd way, which does get more run between Costerfield and Greytown.
Let’s see what Mark thinks !
