Reading the signals is part of the challenge and joy of my railroad photography.

Three weeks back, Chris Guss and I were following a southward Canadian National freight on the Wisconsin Central line.

North of Slinger, we made photos from a wooden plank bridge near the north approach signal for Slinger, Wisconsin.

This displayed ‘green over red’, in other words a clear aspect.

I made these views with my Fujifilm XT1. After exposing the view of the signal, I changed lenses, and used a 27mm pancake lens for the action photo of the passing train.
