This would be the number one route that I would want next in TSW. I have been there myself and I absolutely loved the train action there... Also the Rhein / Rhine is a beautiful valley with magnificent views everywhere along the way. But if it makes it, they will need to make sure that the Hohenzollernbrücke in Köln is as busy as it is in real life... Yes I stood there for an hour next to it watching all the trains passing by.... What an unbelievable amount of trains! ICE's, Talent's and everything in between. I try to say, Hagen Hbf is also a pretty buy place in real life (not so busy as Köln though) but it feels a bit ghost-town-like in TSW. Anyway, huge +1 from me, I hope this one makes it!
If a picture is worth a thousand words, how many words is a video worth? At nearly an hour -- too many, especially without any words, so write something -- as Scarface suggested. Please?
