Making-of post from designers of new map of Metro is here: http://www.artlebedev.ru/everything/metro/map2/process (http://www.artlebedev.ru/everything/metro/map2/process). It is in Russian, but should be interesting anyway.
End result is here:http://www.artlebedev.ru/everything/metro/map2/hi-res/ (http://www.artlebedev.ru/everything/metro/map2/hi-res/). (7087×10630 14 МБ tiff file).
I always preferred geographically accurate maps to symbolic diagrams. It's unfortunate they are quite rare and not very popular at all on official maps. :(
I like metro station name Babushkinskaja :)
I only saw in Moskwa and St. Petersburg exchange stations with different names for different lines. I found this quite irritating.
