I live near the UP mainline across Nebraska-our section has 3 sets of mainline tracks, LOTS of trains going by. Anyway, saw a train of just ALL tank cars, first I had ever seen. Some looked new, but many were just slightly used, no graffitti either! Lots of ethanol plants here, so you see a lot of tank cars, did not notice any ethanol markings on them though, but I was driving at the time! Could be a neat train for someone.
