I really like the way those cars have been rehabbed, Don. Given how substantial those cars are, its good to see them saved.
I run a tank car unit train of various makers 1, 2 and 3-dome cars, and a Sunoco 2555 is always at the front of the train (unless I'm running K-Line die-cast cars). The weight up front generally provides better tracking and operational qualities.
When my father used to stop at our local Standard Oil back in the 50's, I remember him always saying "Hi, Fritz, fill'er up with Ethyl", which I understood to be a higher grade of gasoline. I didn't know it was also a brand.
Well done all!
