At one time the wig wag signal was the standard grade crossing protection. Now the type is all but extinct.
I learned a few weeks ago that Wisconsin & Southern had finally removed the last of these classic American signals on its former Chicago & North Western line to Reedsburg, which had survived at Baraboo, Wisconsin.
Over the years, I’d photographed wig wags at various locations in Wisconsin.
I made these photographs at Baraboo with John Gruber in February 2008.
