Finally, some blurb on the BBC site:-
"Environmental scientist Diane Hope celebrates the quintessentially American sound of the train horn. American railways were built during the days of the Wild West when cattle were free to roam the wide open plains and the horn was used to warn people and animals of an approaching train. Nowadays, however, towns and suburbs have spread along the tracks and people who live close to crossings can hear the horns blasting away day and night. New legislation is being introduced which will limit the frequency and volume of train horn blasts."
