Train Toots
Thanks Jerry
Answer
:
When a
train
approaches a
road crossing, it blows its whistle four (4) times :
Two (2) longs, one (1) short and one (1) long.
In
Morse code that
is the
letter "Q".
This
dates back to
when
the Queen of England would come into harbor aboard ships.
The
ship would
blast
their horn the letter "Q" to let everyone know the Queen of England was
on board and to yield the right of way to it.
Trains
adopted this signal for everyone to yield to it.
