Twenty eight years ago on this day, my brother Sean and I made a survey of the former PRR electrified mainline south (timetable west) of Philadelphia.

Rather than literal interpretations, I was aiming for something more interpretive.

I’d bought a roll of Kodak Ektachrome 160 slide film. This featured a ‘tungsten balance’ designed to work with incandescent lamps and so featured a very cool color temperature, which accentuates the effect of dusk.

My notes from the day are nearly 4,000 miles away, so I can’t tell you which suburban platform on which we were standing when I made this time exposure of a rapidly approaching Amtrak train in the blue glow of the evening.

What I remember most from that evening was a sky filled with migratory birds, chirping, singing and squawking as they flew by.
