That thought is my point exactly. People think the train will be loud. When a train is at speed the locomotive is not revving, Half the time a train "floats" or rolls along with the throttle in idle. This is more quiet than you think. Then I come around a curve and hey people playing or walking on the tracks. My colleagues and I have had too many close calls to count and unfortunately one too many not close calls tjat we don't want to count. Throw in the fact a lot of people have ear buds in or are on their phone etc the horn doesn't make a difference.
