How about this German Rounte from Aachen HBF to Duisburg HBF. Its called the Rhein-Niers-Bahn and currently has the ET425 as rolling stock. I would love to see this, because the ET425 is my favorite Train (The sound of it is so satisfying).
I haven't been to Duisburg (HBF) nor have i been to Aachen (HBF) but from what i have seen so far it looks pretty cool. I also like the idea of bringing the 425 to TSW since its one of the best EMUs currently out there.. But i recommend investing more time in your future route proposals as there are some important thing you didnt mention (such as the route length etc.) Heres the full Wikipedia article about it: https://en.wikipedia.org/wiki/Rhein-Niers-Bahn And a better picture of it
We all have our opinions, but yours doesnt count as one. I can understand that people may not be obsessed with the looks of the 425, but it just isnt ugly at all. Not even mentioning the sound of it, which is probably the best part. To summarize it: You are wrong! Continue to play with your Pacer while i am having fun driving with the 425.
