@Jessabeans , oh such awesome ideas, and I'm in awe of people who can do CAW!!!
@ciane, now that you've brought up that point, I too agree that the windows should be the same on both sides of the train (in case the train cars need to be turned a different direction). So I've done yet another option (lol), as the spacing on those double-grid ones won't work as they will interfere with walls on the other side.
So what if we use a single grid window and use 2 together, like the Taintless Bauhaus one (100 sim pts)? There's also the transcendental one but it's taller and goes almost to the bottom of the trim on top.
And my game doesn't always flag store items correctly, so are the round windows in my picture base game windows?
