A Late Amtrak Northeast Regional 142 With Phase 7 Amfleet at Princeton Junction, NJ

Shown racing past the rail station at Princeton Junction, NJ is Amtrak Northeast Regional 142 to New York running almost 55 minutes late with ACS-64 669 leading & two Phase 7 Amfleet coaches in the consist. The train from Washington D.C. is doing at least 120 mph & 142 was delayed due to an unknown issue on the line south of Baltimore, MD. Another northbound train came shortly after but I was very surprised to see 669 twice in the same day.
