In addition this is frustrating people which inclines some to cross intersections at which lights etc are already going......and again they are going to blow horn more for that. Didn't think it took much to equate more movement to more horns. " |

OK, here's the deal...
Upon approaching a public crossing at grade (level crossing), by law the train is required to sound the whistle in a long-long-short-long pattern. This whistle is to be sounded for a minimum of 20 seconds ending when the train has occupied the crossing if the train speed is less than 45mph, and must be sounded beginning at least 1/4 mile from the crossing until the crossing is occupied by the train if the speed is over 45mph.
These regulations also apply to maintenance vehicles. Since they are smaller than engines or trains, the operators tend to sound the whistle longer and more frequently than train engineers do. They also sound their whistles more often because they stop and start a lot in the vicinity of crossings.
I suspect this is what people have been hearing, since I know of no "directive" that trains sound the horn more than they have been doing in the past.
