Hi,
I uploaded my current savegame to
http://www.mheinzerling.de/exchange/ope ... g_3819.sav
Since our summer was dark, or at least cold I played the game the last weeks and refactored some of your tracks. I currently have no time to go into details, but let me give you some hints how to explore my work: I started at the eastern station and reorganized the SO-track to a clean 2/3-lane mainline with some nice priorizied sideline joins. Borders between the old and the new track layout are marked with '<---'. Sometime the look strange or even causes some jams, but in general this are only places where I have to continue my refactorings. I'm not sure if you like such fancy signalling stuff, but I'm a great fan of it and use it regularly.
In addition to that I continued to compress the NO-tracks to 2-lane mainline and in the eastern part a parallel 2-lane sideline. Since you don't use "wait for full"-order, I had to cheat a little and build some buffers to slow the trains. Otherwise I would had to fix the train order which is a lot of work without shared orders. In parallel I rearranged some of the smaller sidelines. (I favour a consequent right-driven (?) system, with one space field between the directions

).
After reaching the northern station I continued with the NW-lanes, now a heavy loaded 3 lane mainline. If you will follow the mainline you will see that I didn't finished it by now, but continued to move in direction of the centre of the map.
For some stations I couldn't resist to touch the orders an trains. Stations beginning with a '_' have trains with one cargo, equal length and wait for full order. One station with a '.' at the begin is still in progress, I only need some changes to optimize the track layout.
Ok, I think, this is the short summery. Have fun to explore your old playground

Since a screenshot is over 500MB large and none of my tools want to convert it to a jpeg, I can't attach it hear. But if you find interesting part, I would be happy to create some "before/after" shots and discuss my the design with you (and maybe others).
