Amtrak Northeast Regional Train #66 Engine Change at Washington DC

This is the longer version of my previous "Amtrak "Pepsi Can" P42DC #160 on Northeast Regional Train #66" video, but this time we shall continue onwards with Amtrak ACS-64 #616 leading the train. More particularly, you also now have the full engine change clip that I was able to take while we were stopped in Washington DC. Please enjoy the video!
