It's the difference in 3 horns and 2 horns with making different chords. Trains use 3 horns while big rigs and dump trucks use 2 (sometimes only 1). General rule of thumb for deepness: the bigger around the base of the trumpet (not the bottom housing) the deeper the sound. What actually MAKES it lower is the "whistle" diameter in the housing.
Would anyone be interested in having a thread with recordings of different types of horns? With so many different ones coming up I think it would be helpful.
