I believe that final "." is the end-of-sentence period, not part of the signal. https://www.up.com/aboutup/funstuff/horn_signals/index.htm shows a bunch of these. The canonical reference seems to be the railroad General Code of Operating Rules - current version is at http://fwwr.net/assets/gcor-effective-2015-04-01.pdf. The "grade crossing" is shown as "= = o =" meaning "long long short long", or "--.-" (which as a single character is "Q" in International Morse, and as far as I can tell is an unassigned sequence in American/Railroad Morse) or "TTET" in either version of Morse. I don't see any obvious correspondence between the meanings of the signals, and a straightforward mapping of the long/short blasts to dits and dahs in a single Morse Code character. There may, of course, be history behind it (as you suggest)... or they may just be fairly arbitrary choices. ------------------------------ Message-ID: <2C5D177E-B918-44C5-BAEC-F91D09A3A47D@roscom.com> Date: 3 Jan 2019 09:48:07 -0500 From: "Monty Solomon" <monty@roscom.com> Subject: Ajit Pai thanks Congress for helping him kill net neutrality rules Ajit Pai thanks Congress for helping him kill net neutrality rules Democratic effort to reverse repeal fell short as Congressional session ended.

I fear you have read the final period as being part of the signal. The grade crossing whistle is long long short long, all evenly spaced, as specified in the "General Code of Operating Rules". I've heard it all over the country. Some other whistle signals are: - stopped, air brakes on -- brakes released, proceeding ... backing up -. approaching men or equipment near tracks .. proceeding past men or equipment, repeated ........ hey dummy, get off the track ------------------------------ Message-ID: <c04e352a-300c-9812-3a39-a70acf7d586f@ieee.org> Date: 4 Jan 2019 14:42:44 -0500 From: "Eric Tappert" <tappert@ieee.org> Subject: Philadelphia Fire boxes Folks, Just a bit of trivia - the fire box in Philadelphia in front of Independence Hall was box 1776.
