In the Middle of a Lap Siding

CSX has removed some of the lap siding on the Toledo Subdivision that the Baltimore & Ohio installed years ago, but it kept the one in Cairo, Ohio. Shown is steel train K596 coming out of the northern end of the siding and onto the main.

If you look carefully, you will see that the dwarf signal is giving a train in the southern end of the siding a clear signal to come out onto the main.

Out of view is CSX manifest freight that is meeting the K596 here.

Note that lead unit SD40-2 No. 4008 has one of the square cabs CSX gave some of these units when they were rebuilt. This locomotive was originally built for the Seaboard Coast Line.

    Under CSX Color Position Light (CPL) signal rules, it requires a top white pilot light for a signal to be “clear”. So the dwarf signal in the photo is displaying “Slow Approach Slow”, meaning slow speed through the turnout, approaching the next signal not exceeding slow speed (15 mph). A couple of notes about the differences between the old B&O CPL signals and the modern Safetran Color Light Signals, B&O signal indications are the safe for both dwarfs and high signals, and the newer signals cannot display “Slow Approach Slow”. A B&O CPL signal could potentially display 22 indications by the time they were discontinued, although very few signals ever had all the lights necessary to do that.
