Interior of your average D.C. Metro train car. It may run smoothly (most of the time), but the interior of these cars is so 1970s. I mean, I really like orange, but too much orange naugahyde ("The real performance fabric!") is just not a good thing. The green line has a few new cars with the same design but a new color scheme—red naugahyde and carpet. Those cars generally smell better too, but that's another story...
