@ciane, I tried all those window except the India one. Tried the Zen but not India. LOL I'll have to go try it.
I had tried those windows too Sandy and thought house window but after staring at the pic of the blue car and trying to figure out why the windows all look so big inside the car and so small on the outside, I changed a few things and tried those windows again. Not really a fan of the crank on the window but… I still went 22 tiles long because I'm not liking changing the window size and I didn’t see the small round windows on this one so I skipped those.

Notice how the bottom of the door is not at the bottom of the train? So I added a 2 step frieze to raise the floor on the inside but let the outside look taller. The frieze could probably be a step or 2 taller considering where it hits the guy standing there. I didn't have a sim on the lot to check the height. Played with the wall paper some more and came up with this…
