RD posted:Again thank you for the info Jack..I appreciate your help.
Now I just have to de-cipher Scotts order/ reservation pages to figure out which run / re-run of what has the AA that I need...
For what it's worth, I just returned from Berwyn's Hobby Shop, and the two Lionel CB&Q A-A units on the shelf are E7A units.
I would STRONGLY recommend the Sunset/3rd Rail E8A or E9A units, both powered, for your CZ train. The biggest difference between the E8A and E9A, as I mentioned above, will be the black front nose strips on the E8A models for pre-1960, vs. the red nose stripes on the E9A models for post 1960s.
