Railway map?

[greycat]

The railway network in Asia Minor and the Balkans seems rather more extensive than that described in any of the WW1 books I have read. For example, their are two lines going north from Salonika rather than the one I was expecting. Also, I understood that the nearest railhead to the Caucasus on the Turkish side was at Konya; however the game has a line up to and across the border with Russia.

I would be interested to know what the source map for the game was.
