YES! It is loud. Apparently we saw a Drunk stagger down the tracks past the stopped train. Then on the scanner at the viewing platform, the engineer on the northbound empty drag said he was walking on the tracks dead on. Then as I was rolling film they said he was on one of the Intermodal's cars. The lead engine #547 had a very great and LOUD Horn. I think it was a K5LA. Later after the train passed, the police arrived and the drunk was arrested.
