Ever wonder about the toot toot toot of the train whistle in Seven Lakes? The Long Long Short Long is the morse code for the letter “Q“, which back in the time where the Queen traveled by Ship in England, ships with the queen on board would do the L-L-S-L on the horn to announce this to other ships in the harbor to get them out of the way.
Whenever the queen switched to railroads, the same signal followed and the engineer would do the L-L-S-L coming into the station to allow some space for the Queen.
When the US Railroads began the train masters from England began using this as a signal and it stuck to today.
