Hot Water postedFor 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.
Jack,
Thanks for the STRONG recommendation .. just got a confirmation e mail from Scott.. I'm in for a set of CB&Q AA E8s .. the ones with the black nose stripes....
