Conrail PIAL-2 had a surprise for us on this day in the form of two Santa Fe units spliced between the usual Conrail road power. PIAL is seen crossing the Lehigh River just before entering Allentown Yard. This power would return west on ALEN later in the day.
The EMD SD (special duty) series are a strong and reliable kind of locomotive which still serve America's rails today. They have proved themselves reliable by clocking in several million miles of freight service over several decades.
