I've noticed, that the most of the TSW2 rolling stock is very shiny. If that extra shine is removed, trains may look more realistic, because in real life trains are almost always weathered.
I agree, but wonder if there's a licensing thing that means the trains can't be shown in dilapidation? I'm pretty sure that Airbus don't allow Asobo to show the 320 in a broken-down state in Flight Simulator, and it detracts from realism there too. If there isn't such an agreement I'd also like to see weathering, though.
Yeah, I think SNCF didn't want the TGV to be weathered so that's why they are so clean in Marseille-Avignon
