Was a bit confused with the service layers to koln Aachen- wondering if someone could explain the layers?- what extra services do add ons bring?- like Rhine Rhur Osten thanks
I'm finding Köln-Aachen quite busy now - much better than when I downloaded it originally. Even getting held up on the way into Köln by traffic meaning the LZB/ATO slows the train and then drives it between the caution signals - clever stuff.
