In this June 30, 2010, view. I’m looking downgrade (west) from the ‘Railfan’s Overlook’ at Cassandra, Pennsylvania. I’ve set the 100-400mm at its maximum focal length to capture a set of light helpers drifting west toward the signal bridge near Portage. In the distance an eastward train is climbing. While the signals are incidental, they offer a touch of PRR heritage. A wink of sun improves the composition. The exposure was at ISO200 f/5.6 1/500th second with Canon 7D.
