Though gone for 50 years, there is still a plethora of infrastructure built by the Pennsylvania Railroad that still exists today. Two such examples are Hack Lift Bridge and the Hudson & Manhattan Lift Bridge, both located in Kearny, NJ.
Pictured is Conrail Shared Assets local PN-13 coming across Hack Lift Bridge on the Passaic and Harsimus Branch with ES44AC 8102 painted in tuscan red, which pays homage to the PRR.
