In modern British railway practice positioned a locomotive at either end of a consist is described as ‘topped and tailed.’
Wednesday evening, Amtrak’s Keystone 649 was running slightly behind the adverstised and featured Siemen ACS-64 electrics at both ends. On the front of the train locomotive 640 led a venerable former Metroliner cab-car.
I’d been tracking 649’s westward progress. It was dusk when we opted to park off Hoover Road near Gap, Pa., to roll by the train. I made these panned photos of the passing train using my Nikon Z7-II with f2.8 70-200mm lens.
