The West Rhine Railway is a 152km railway line running from Koln HBF to Mainz HBF, I will be talking about the 81km line from Frankfurt HBF to Koblenz HBF on the Western bank of the river Rhine, this railway could provide the most diverse German railway in the game due to the large usage of both electric and diesel trains. Leaving Frankfurt the line passes Frankfurt Airport, after leaving the airport the railway crosses over the Südbrücke crossing the Rhine before entering Mainz, the railway then follows the the banks of the Rhine until arriving at Koblenz passing tows such as Bingem Am Rhein and Oberwesel There are several passenger lines that run on the line (I probably have missed some), such sights along the way include the remains of the Hindenburg Bridge near Bingem which as destroyed in March 1945 by retreating German forces, Rheinstein Castle, Ehrenfels Castle, Binger Mausetrum and the Sooneck castle to name a few PLAYABLE SERVICES IC/EC 31: Kiel-Hamburg-Passau (Koblenz, Bingem, Mainz, Frankfurt) Operator: DB Rolling stock: DB BR 101 IC/EC 32: Berlin-Dortmund-Innsbruck/Tubingen Operator: DB Rolling stock: DB BR 101 RE2: Koblenz-Boppard-Bingem-Mainz-Frankfurt Airport-Frankfurt HBF Operator DB or Vlexx Rolling stock: Stadler Flirt LINT 54/81 DB BR 143 + 4 Dosto RE17: Koblenz-Boppard-Bingem (continues on the Nahe Valley Railway) Operator: Vlexx Rolling stock: LINT 54/81 RB 26: Koblenz-Boppard-Oberwesel-Bingem-Ingelheim-Mainz Operator: Trans Regio Rolling stock: Siemens Desiro ML (both 1 and 2 train sets) Rhein Main S-Bahn: S8 Operator: DB Rolling stock: DB BR 430 several services run on the line between Mainz and Frankfurt that can be playable, they are as follows and what train is used on that service ICE 20: ICE 1 ICE 31: ICE 1/ICE T ICE 41: ICE 3 ICE 42: ICE 3/ICE 4 ICE 50: ICE T ICE 91: ICE T IC/EC: 30 IC: 31 IC/EC: 32 IC: 35 RE3: Vlexx BR 620/622 RE14: DB BR 429 RB31: Vlexx BR 620/622 The West Rhine Railway is one of the busiest railway lines in Germany for freight, and only got busier after the Koln-Frankfurt high speed line was opened and the relief of ICE services meant more freight trains could run on the West Rhine Railway possibility for addons: DB BR 146 in DB IC White and Twindexx coaches DB BR 147 in DB IC White and Twindexx coaches DB BR 120 with IC coaches BR 193 in MRCE black BR 151 in Hector Rail and DB liveries DB BR 218 DB BR 111 DB BR 761/762 (3rd Generation Dosto) Trains that can be layered DB BR 101 ICE 3 DB BR 420 DB BR 155 DB BR 204 Photos can be found here: https://imgur.com/a/y7U7uw0
