Where are and or when will we get American trains? I’m sorry but European trains are so boring and ugly compared to American steam and Diesels. I mean who can beat a big boy? or challenger? or the sharp looking diesels of that time? I don’t understand why that wasn’t a part of the game from the first.
Urban Games is located in Switzerland, so they built Swiss trains first.
Anyway, there a are a lot of mods around, as FX2K pointed out.
About the Big Boy: there was a discussion in the German forum pointing out that the Big Boy was to big for the Sharp Curves which are allowed in TF, making turns look ugly. I think nobody builds a mod for it at the time, sorry.
