Nowadays, it seems that any Class 1’s locomotive can show up anywhere in North America. In the 1970’s, foreign power showing up in a distant location was more uncommon. The Delaware & Hudson’s “Apollo” intermodal service to Oak Island would sometimes have UP power, but those trains were elusive and often nocturnal. Here a westbound Apollo makes a setout at Allentown on an overcast July morning. For some reason, I couldn’t stick around to get the train on the road, but any shot of UP power in the Lehigh Valley was a relative rarity.
