The morning of July 1, 2010, was clear and bright. I set up on the outside of a curve near Lilly, Pennsylvania, to get a good view of the automatic (intermediate) signals at 254.7. Here NS maintains three main tracks with the center track signaled in both directions. This arrangement stems from a Conrail-era modification in the 1980s, when it converted the line from PRR’s directional four-track system (the two south tracks were for eastward trains and two north tracks reserved for westward trains). In this view of NS freight 12G, I used a 100-400mm Canon zoom with my Canon 7D mounted on a Bogen tripod. The lens is set at 285mm; image exposed at ISO200 f/9.0 1/250th second. By using a long focal length aimed directly at the signals I’ve maximized the effect of the position light arrangement.
