So I have seen a few reddit post about this route and I just couldn't get it out of my head. This will be a fantastic addition to the game!! Frankfurt to Köln High Speed Rail with a Spur to Mainz is a no brainer route to create. This will be a high speed route connecting Frankfurt to Köln via the 180kms of High speed line where the speed limits go up to 300kmph!! This route can be much better than Schnellfahrstrecke: Kassel-Würzburg as this route wouldn't just include the 180kms High Speed line. This route will also have your regional trains, S-Bahns & also some shunting and/or freights trains. This route can feature S-Bahns line S8, S9, S12 & S19. There will be Regional Trains too! (These are all the drivable trains in the route) In total the length of the route with all the spurs will be around 230kms. There are also around 6 yards and/or factories in this route which can be used for freight Services and Shunting which can make the total length reach to around 240 to 250kms!! With such varied services we will have multiple rolling stock too! The main rolling stock for this route would be the much anticipated ICE 4! The other Rolling Stocks would be: ICE 4 (New Rolling Stock) DB BR 430 (New Rolling Stock) DB BR 423 DB BR 363 *Note: These rolling stocks are for the ICE, S-Bahns and Shunting services. I couldn't find which rolling stock would be in use for the Regional Services and for the Freight Services. With the New Route Hopping feature, you can route hop to: Linke Rheinstrecke: Mainz-Koblenz from Mainz Hbf Kinzigtalbahn from Frankfurt Hbf Schnellfahrstrecke Köln-Aachen from Köln Hbf You can also go upto Kassel if you have Schnellfahrstrecke: Kassel-Würzburg & Kinzigtalbahn. If you have all the routes mentioned above you can go from Kassel to Aachen, the distance of 450kms! Or from Koblez to Kassel, the distance of 330 kms!! Here is the link where you can find the route! Hope this gets some tractions and is possible to create!! https://metrodreamin.com/view/U29zS25mRnZqTGZveXJlUDA4Z3JYd3l6SU10MXwyMg==
