Note (1): There were two ropes with a length of rubber hose (about 18" each) on them where you would pull them down to sound the horn. One was for the "City" tone, which was lower in volume than the other, "Country" tone which was louder. Both ropes led to separate valves on the cab ceiling. If you grabbed them both together, you could make even more noise.

Further trivia: Because of clearance issues at various locations, the horns were mounted on the engineers side of the car body, on the side (not the top) of the engine, just ahead of the smoke deflectors.
