Be assured, as I’m a German who uses our railroad to get from Kiel to Stuttgart and back on a more or less regular basis, there are those Bombardier Locomotives with Display 😉
I guess, it’s only called Class 185 ingame due to licensing issues, maybe the license costs too much and Urban Games cant afford it?
But thats just a wild guess by my side, we need a comment from the devteam itself to be totally sure, why the Class 185 is called and looks the way it is ingame.
I think a mod should be without problems though, for example, SCS Software, the guys who made Euro Truck Simulator 2, don’t have a license for the Mercedes-Benz-Trucks, so they’re running as the fictional brand “Majestic” with an edited star, but the Community created dozens of mods to let those trucks appear as their real Mercedes-Benz-Counterparts.
I didn’t hear of someone getting sued for making a mod, probably because the modders don’t take any money for it, so, as long as you don’t take money for distributing a mod, that gives the Class 185 its full name and appearance, you should be good to go.
