With the game currently holding the Rhein Ruhr S Bahn route, it would be great to have the Rhein Main included. Rolling Stock ET 423 The 423 is the most common train to run on this line, and was built from 1998 - 2007. The train has 2 motor types, it would be a cool feature to have different sounds and randomize it or be user choice depending on the series. ET 430 (could be added later) The 430 was newer and is pretty much a BR 422, same motor and manufacturer but different body shape. They were rolled out in 2012. Where it could go The line could be situated in the citytunnel and most busy part in central Frankfurt. As a public transportation system it would be great to see the city of Frankfurt when it pops out of the tunnel as having the tunnel as the main route would be way too short. As for the line it would run on, that's up to you DTG Seen here is an BR 423 train in the City tunnel at Taunusanlage station. I will look like an idiot if any of this is wrong, i'm not german anyway
