    @JLChauvin: Can you direct us to more information on those signals? I've never heard of them, and 5 minutes of googling hasn't yielded much.

    Hello Jovet,
    The rule I was referring to was for Searchlight signals and I understand the reason behind it. My sentence was more of a tongue-n-cheek joke in favor of Position light signals As far as I can remember only the lines west used the two red lights in the PRR position light signals top head in a two head signal. What the real reason for doing this was I'm not sure? But if I were to guess I'd have to say to help simplify the wiring and since the middle light was not lit, the two outer lens would had to have been changed to a color other than amber so crews would not report a burned out middle bulb.

    I may be a bit biased, but my favorite signals are the GRS 'SA' Type target signals of the NYC-PC-CR era...now rapidly being replaced by CSX.

    I'm surprised nobody has come along stating crossing signals are their favorite.

    My favorite would have to be SP style Searchlight Signals.

    One of my favorites: direction indicator from the obsolete 1885 French code.

    The top arm applies to the direction on the extreme left, the second to the next direction in order from the left, etc. Bye night, a spectacle projected light from a lantern (backward lighted) to mirrors fixed on the arm. A purple light was for OFF (fermée) direction(s), green for an ON (ouverte) diverging direction and white for the ON (ouverte) straight direction. There was no difference between ON straight and ON diverging directions by day (removed or unlit lanterns).

    I am curious: did the purple aspect shown here give any rise to the current purple aspect used by the SNCF? I take it this signal was a mainline signal?

    This was from the now obsolete signal code.
    Nowadays code is different:
    - yellow is for cautions indications instead of green in the old code
    - green for clear (mainline) instead of cautions indications in the old code
    - white for clear (service tracks) instead of clear in every tracks in the old code
    - purple for absolute stop on service tracks (or turn-back signals on main line) instead of direction indication in the old code.

    Here is a link to the old code, in English:
    And a link to the nowadays code, in English:

    Finally a group where I can air out my fasination with semephore signals!!
    I grew up just outside of Chicago, along side the old Soo Line mainline. A few blocks to the north the Soo Line crossed the Chiciago and Northwestern (Metra) and old Milwaukee Road and Northwestern freight tracks. The Northwestern line used three color lights laid on its side, however the Soo used upper quaderant semephores. Maybe it was the animation of the falling arm as the train passed......
    If I could figure out a way to get a three headed semephore bridge signal to work I'd have them on my HO layout!!

    If you like semaphores, here's a fantastic shot in ye olden days of Chicago: http://railpictures.net/viewphoto.php?id=80546

    I'm not sure how you'd get a HO semaphore on a signal bridge to work, but if you don't mind looking at "ugly" rods, it might be possible. Not all of the arms probably have to move, either.

    Hank and I both have semaphore sets for MSTS you may enjoy playing with.
