I spotted this now very rare late 1970's era photograph on the interner recently.

Seen here on a piggyback ( Truck trailer on train.) freight train at Thorndale Junction Pennsylvania, are five former 1930's era former Pennsylvania Railroad GG 1 electric locomotives.

These locomotives had spent their final years in operation hauling freight trains for Conrail, commuter trains for New Jersey Transit, and Amtrak passenger trains as well.

These 5 examples that are shown here, are working their last full year of electric powered freight train service under Conrail. 1979 was the year that Conrail had discontinued all electric freight train operations in the northeastern United States.

New Jersey Transit was the last operator of these classic locomotives, and retired theirs from commuter train service during the Fall of 1983.

Several of these have been preserved in Museums around the United States, including one at The Illinois Railway Museum in Union Illinois.
