Acela Express 2124 & A Late Amtrak Northeast Regional 197 at Cornwells Heights

Acela Express 2124 to New York flies past the rail station at Cornwells Heights in Bensalem, Pennsylvania with Power Cars 2035 & 2039 followed by Amtrak Northeast Regional 197 to Washington D.C. running 17 minutes late with ACS-64 660 on the point shortly before I packed it up. 197 was delayed due to an unknown issue on the line north of Newark, NJ & a commuter train to Philadelphia makes an appearance.
