all 4 mainlines now completed - still need to add in some points (switches if you're an American) in places, sidings for the railfreight terminal, and rework the fiddle yard, but the basics are almost complete. New version coming soon...

I've got one line completed now. The other 3 should be finished by next weekend (I hope). Basic fiddle yard is down but will probably be reworked now that I have completed the lower level.
