Nice @romagi1! I like that extra bit of trim on the top. The store windows do look better, I think; and as long as they aren't tied to a world, I think they'd make a great option.
Lunch is over and the dogs are eating now. I've got the little Elf Express added to Sunset Valley next to the Crumplebottom place thinking that is where sims would come into or go out of town on the train. The three 20x25s worked well there, though I did have to turn a couple trains to face the opposite direction. I'll practice colors and windows on them.

Will these train cars work either direction as well?
