'W' for railroad whistle

In advance of a grade crossing.  You might think that 'whistle' is archaic as diesels and electrics have horns, but it's traditional.  Another thing which is traditional is that the sequence of 2 long, 1 short and then 1 long blast in North America is Morse Code for Q meaning "the Queen has Right of Way."
