American Morse Code

American (Railroad) Morse

American (or "Railroad") Morse Code was the original Morse code developed in the 1840's by Samuel Morse and used extensively in the USA via telegraph wires. It was enthusiastically taken up by the railway companies but later replaced by International Morse code which was technically more suited to international telegraph communication.

American Morse was mostly heard through Morse "sounders" which make a "clunk" noise rather than the more modern "beep" noise common in Morse radio communication (or "wireless telegraph" as it was first known). The tools here provide both listening styles, but historically there is very little overlap between American Morse and the "beep" style of listening.
