Amtrak Keystone 671 With Two Locomotives, A Late NJ Transit Train 7864 & 7869 at Princeton Junction

Amtrak Keystone 671 to Harrisburg, PA flies past the rail station at Princeton Junction with two ACS-64 locomotives (639 & 628) on both ends. NJ Transit Train 7864 to New York then arrives shortly after running almost 16 minutes late with Cab Car 7009 in charge & ALP-46 4607 on the rear followed by Train 7867 to Trenton led by Cab Car 7047 with ALP-46 4625 trailing. My reaction clearly tells it all after the third train leaves since this is what I hardly ever catch at all anywhere on the Northeast Corridor. 7864 was delayed for some unknown reason & 671 has four Phase 7 Amfleet cars in the consist.
