Was the ALCO engine an active participant then? Also, I was led to believe that the the middle axles on the PA were powered for the experiment, A1A-A1A going to C-C. Do I understand this correctly?I believe that is correct. According to Diesels of the Union Pacific Volume 2 by Don Strack, the turbine produced 5000hp and the cab unit provided 2000hp and was on C-C trucks. They appear to be the original trucks, so apparently traction motors were added to the center axles, though I didn't know that could be done with those trucks. I would imagine that the PA retained its Alco engine to produce the 2000hp, as that was its original rating.

What's most embarassing is that the C-C is also in the UP 1934-1982 Volume 1 book that way. At least four pairs of eyes proofread the manuscript, but no one caught the mistake. But I can fix the web page.
