I have made a Simutrans featurelist at http://www.simutrans.de/start:features (in German)
I think that can somebody translate into English for http://www.simutrans.com/about.htm#Game_features, if it is needed.
If anybody give me a link to this site I will be pleased. :)
I can't read German but that list looks way too short :) Feature summary perhaps?
Seriously though, good work ;)
