Old General Railway Signal Semaphores In Corn Country.
CSX’s former Monon was among the last bastions of semaphores in automatic block territory in the United States. I made this image on the morning of June 24, 2004. While the line only saw a few trains in daylight, there were enough moves to keep the signals busy.
I wrote about this signal installation in my 2003 book, Railroad Signaling, published by MBI. This has since been reprinted as a softcover book. See: Quayside Press.
