Back in Blue. On evening of Wednesday, August 19, 2020, Amtrak 137 (606, ACS-64 leading) crosses the Delaware River from Trenton, NJ to Morrisville, PA. Over the winter, the unit wore a wrap for Coca-Cola and was the target of many lenses along the Amtrak Northeast Corridor Line. It has since returned to the fleet and relative anonymity amongst it colleagues. The evening light highlights the train on the 1903 Pennsylvania Railroad Bridge.
