Trackside Details - Elevated Signal Instrument Shed - Telegraph Pole - Tell Tales

Discussion in 'Right of Way' started by mike, Oct 12, 2001.

  1. I have a dumb question.

    I've always wondered this, but what exactly are tell tales and how do they function?

    I know what they look like, but what is the purpose for these?

    Ship it on the Frisco!

    As I understand it, they are a warning for a man walking/riding the roofwalk on a car that a low clearance area is approaching.

    It is better to get hit in the head with a chain or rope hanging below the bar than a bridge beam, tunnel portal or other low clearance structure.

    Paul is describing the use of telltales exactly.

    Take a look at these two pictures from Cape Girardeau.

    The telltales were not on the Frisco, but the MoPac spur, formerly the Cape Girardeau Northern - one of Louis Houck's railroads.

    They guarded the viaducts under Morgan Oak and Good Hope Streets.

    Telltales were installed in Tulsa east of the overpasses at the Tulsa Union Depot.

    The ones on the east end were still in place when I hired out in 1971.

    Those bridges were low with 1930ish clearances, and the telltales served their purpose well.

    I don't remember any on the west end, but they were probably there also.

    Keith, those are neat photos.

    I can remember when they filled in the old Houck line "cut."

    While not serving quite the same purpose, a modern-day version of tell-tales are being installed in Indonesia in order to deter "train surfing."

  6. Ok, thanks for the answers.

    I might add a couple to my layout when it gets underway.

    Ship it on the Frisco!
