In Alton, IL there is a short stub of four arm pole line left along what used to be the Chicago and Alton main. The line was bypassed and routed around town years ago, which eventually became GM&O's STL to Chicago main. From there it went on to serve ICG, CMNW, SP, and now UP. This part of the line is still served by UP to access a grain elevator. The pole line is actually still in service, providing power and several wires for three grade crossings, two of which have working wig-wag crossing signals. Here is one of the wig wags. [id=177538400]
