Hello everyone, Here is my first route suggestion, I hope you guys will like it ! So my suggestion is the Frankfurt-Fulda route, which could connect to the Kassel-Würzburg SFS route, creating a long itinerary through middle-germany. I'm not German, but I took this route many time and it looks nice, as well as it got many different trains running on it. There could be ICE trains such as the ICE 1 already in the game, IC traffic with the BR101, and of course regional trains with the RE50 and RB51 lines. The route could also start from the suburbian city of Hanau if the Frankfurt City is too big/much to modelize. Here are some pictures The route on google maps. It takes 56 minuts from start to end the ICE. RE50 on it's way to Fulda
If you want a big network out of this then you need to extend Main Spessart Bahn by making out Main Spessart Bahn West Hanau Aschaffenburg and then this route Kinzigtalbahn or SFS Hanau Gelnhausen Fulda. Sadly sleeper train doesn't go up this way anymore. Instead it goes up the whole Schnellfahrstrecke Hannover Würzburg full name of KWG
You got to be thankful for having your suggestion made into the game. My suggestion the Babylon Branch ended up being built as the LIRR Jamaica Sutphin Boulevard Archer JFK airport to Lydbrook section of the new LIRR route.
