NOEL apparently worked the ex NYC from Selkirk to Buffalo a fast, relatively flat railroad. I worked on the ex PRR side from Jersey City to Harrisburg/Enola a high speed railroad but some stiff grades and two westbound helper districts. The first from ZOO in Philly to Paoli and from Thorndale up to Parkesburg and even further up and over the A&S branch. My recollection of the six axle Century Alcos was their ability to run at slow speed in coke, iron ore and coal train service. The few occasions I had them head out on a freight train they were O.K. but all their trouble seemed to occur at high speed. It was a crap shoot if they would make transistion electrically allowing the train to accelerate to a higher speed and once you got up there( 50-60 mph ) ground relay trouble might force you to isolate the engine for the rest of the trip.
On the PC all mineral trains had a maximum speed of 30 mph and here the Alcos shined. Most of our piggyback trains that were diesel powered had a combination of SD-45 and SD-40 power. Back in 1974 they started running diesels straight thru to the Meadows on Mail 8,9,10 and 11. Power was usually SD-45s and we ran them 80 mph. They only van trains assigned four GP-40s were TV-79 and TV-10, when TV-10 ran as solid meat train from Chicago to Weehawken via the Penn side. So to answer the question it was EMD 95% of the time on the hotshots on my side.
