It's awesome that our "seasoned" citizens share those memories for us
all, lest we forget the sacrifices made in past times.

I was 14 in 1944 when this took place at the Chesapeake and Ohio main
office in Richmond, Va. WW-2 was "total" war. Resources were
strained everywhere and workers were scarce because most of the men up
to 35 were in the army or working in defense plants. All the railroad
telegraphers at the C&O were probably in their 60s or older, so I
suspect they might have been called out of retirement to man the
railroads communication system. Back then nearly everything moved by
rail; people, war materiel, troops, domestic freight, etc.

well, how old *is* Gerry? the version of code we learned and use was
standardized in the 1860s,... ;-P
understand that Western Union hung on to the old version into the
1920s and maybe a little later (since they were mostly only talking
amongst themselves on the wires), but the point is that even that had
long and short dashes.

you're not going to find the old 'American Morse Code' anywhere
now but in Museums or those games where people dress up and try to
reenact some historical event.
cheers!

"clicks"?
sounds like a common misconception; reality is that Morse
code is made up of signals of varying length and timing (be
they sent by tone, or light). it's possible to use tones to
substitute for short or long signals,
Gerry is correct. Telegraph morse code (later called "american
code", or "railroad code") is clicks only. It is the sound of
the solenoid that originally marked a paper tape. Operators
learned to copy by sound only and skip the paper tape. That was
in the 1840s. The is a dash in the American code, but the way
it sounds on a sounder is not at all dash-like to CW operators.
The "clunk" of the release is a bit different sounding that the
"click" of pull-in and the time between them is the difference
between a dot and a dash. Actually, initially there was two
lengths of dashes.
but reading code of just identical "clicks" would be difficult
at best, but more likely, impossible. imagine; how would you
be able to identify a "click" as a Dit (e) or a Dah (t)?
Heh. Tell that to the many thousands of railroad telegraphers.
The did it for over a hundred years! Not each one of them, of
course - but as a whole. *smiles*
