Among the surviving vestiges of the infrastructure-intensive Pennsylvania Railroad is the pin-connected truss over the Main Line at Whitford, Pa.

This was part of a grade-separated freight cut-off built when the railroad was America’s largest and the most intensive freight hauler in the United States. This arrangement underwent a transformation during the Conrail era. Today, the PRR’s main lines east of Harrisburg are largely passenger routes.

I made these photos with my Nikon Z6-III fitted with a 24–70mm Z-series zoom. Until recently, I’ve largely used my Z6-III for low-light photography; here I’m working with it in bright sunlight.

NEF RAW files were adjusted for color and contrast using Lightroom.
