If you are asking for votes on needed cars, I would love to have a 10,000 gallon single-dome AC&F Type 4 tank car, the one with the high walkway (6,000 and 8,000 gallon sizes would be nice too).
Well, gee - if we're going to get another poll going, let me suggest a GATC 8,000 or 10,000 tank car. I could use both in large quantities. Also a tank car (any builder, I don't care which) with a LARGE dome.
