Thanks Guys,
After seeing 3RD Rail 3 dome tank cars at York I also suggested to Jim Weaver at Atlas years ago that Atlas should add a 2 and 3 dome O scale tank cars to their Steam Era Classic line. I have several Inter Mountain and Atlas 8000 gal. tank cars The detail on these cars is outstanding.
I looked at the tank cars long and hard at the Chicago show. The 3rd Rail cars were very pricy, even after Norm worked with me if I purchased two cars. My uncle worked for Koppers in Memphis for many years, so I had to have that car. The Roma wine tank car was also too nice to pass up, so I ended up with both of them.
I found the 2 and 3 dome cars on a table across from Norm's display. I made a few stops at the table and finally made a deal to buy the two tank cars and a single dome Sunoco tank car. I am keeping the two rail trucks and Kadee coupler on the Sunoco tank car. I am assembling a string of two rail O scale freight cars.
Thanks for posting the pictures of the prototype tank cars.
