please don't forget the red stripe at the top of the ÖBB Eurofimas
I didn't forgot it... but, I have problem with this part... same thing is on HŽ wagons... there is another stripe above 1st class yellow stripe...
But, this is part of roof and I have to figure out how to make it (problem is in roof mesh and UV map for that part)...
Well, as I said before... work in progress... 
As to the passengers, I think it would be a lot of work to add them for TF
Passengers is not big problem... I already made some testing meshes and they looks just fine (also, because 2nd class wagons have 66 seats = 66 passengers, I tried keep passenger meshes low-poly as much as possible).
