Here is the eastbound CPL at Carbon Siding in O'Fallon, IL, 11/9/2005. It normally shows dark until a train approaches. Unfortunately, like the others, it will soon be replaced by something more mundane and standard. With few exceptions, CSX's ex B&O lines are the only places these can be found. One UP line also uses them, and those are also in the midst of replacement. http://n691lf.rrpicturearchives.net
