Well, I seem to be almost answering myself in this thread. C'mon folks there must be some add'l Western Road folks out there in forum land This is a Marx Western Pacific E-7 A-B-A consist , The A units from1956-1960 and the B unit from 1957-1958. Like many of Marx's powered units, these gal's run real fine and pull quite well given they are going on 70 years old. I consider that a testament to some good reliable design on the part of Marx.
Best Wishes and hoping some other folks decide to join in the posting party!
