Horn Sequencer The lead locomotive in the southbound train, UP 9707, was equipped with a horn sequencer that is designed to sound the âlong, long, short, longâ highway-rail grade-crossing horn cadence.
All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, like the Daboll trumpet, used vibrating plates or metal reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a revolving cylinder or disk, in the same manner as a siren.
