On the cab signals, the system requires a different voltage than regular control circuitry - not really a large problem - and must be wired / plumbed (on an air over electric system like an old steamer) into the Train Control / Automatic Train Stop system - more complicated...and only necessary on some territory. Usually such problems are addressed by putting an "Equipped" loco ahead (not desirable in this circumstance). I don't know if this was an NS decision (not to equip the 765), or why it might have been done - after all, the PRR ran similar steamers, including K4 #1361 which all had cab signals. Don't know about GEVOs with HEP, but the baggage car (behind the Ft. Wayne Society car) appears to have grills and roof structure hinting at a HEP unit...a common fitment under the circumstances. Doesn't the UP 844's train also supply HEP that way ? A fabulous display...didn't get to see it live...thanks to all those who posted great flicks & pics on the web ! Bob C.
