Working with the Amtrak/Via Real Time Live Map ap (https://asm.transitdocs.com), I was able to pinpoint within a few minutes when Amtrak 654 eastbound from Harrisburg would pass Gap, Pennsylvania, where Kris and I were waiting for the train.
This Amtrak train featured a short push-pull consist with a former Budd-Metroliner cab control car at the east end and ACS-64 625 at the back.
To stop the action, I set my Nikon Z6 at 1/2000th of a second and exposed bursts of photos as the train zipped by us.
