Number 600 is the first of Amtrak’s Siemens Mobility-built ACS-64 electrics. This was named to honor Amtrak president David L. Gunn.

I made this high-speed broadside pan of the class leader as it worked the back of a Keystone train at Atglen, Pa..

I’d set my Nikon Z7-II camera in aperture priority mode and designated the aperture setting at f3.5. This allowed the camera to select the correspodining shutter speed based on the camera’s preselected pattern metering. When I release the shutter, the shutter speed was at 1/800 of a second. (ISO was set to 200)

Owing to the speed of the train, these setting allowed for a slight blurring of the background and foreground, while my panning motion kept the locomotive crisp.

Working with the NEF RAW file, I adjusted the highlight and shadow areas in post processing. I’ve posted two versions below, one is slight brighter with lighter highlights than the other, reflecting nominal changes in post processing settings.
