I know that GE provided Alco with their AC/DC transmission system before they introduced one of their own locomotives with it. However, after GE introduced the U25B to the market, in general did they sell to Alco their latest locomotive transmission electrical equipment as they developed it?
Over the life of the Century series of locomotives did Alco progressively update the transmission electrical system of the various models with improved components/subsystems? For example I believe that the C628 had the longest production run of any of the Century series. Were the transmission electrical systems such as the wheel slip and generator excitation systems on the units built in Dec 1968 the same as those on the units built in Dec 1963? Or were they improved/different versions?
Thanks.
