[Mr. Lucky]

The horn (or previously whistle) signal for approaching a crossing hasn’t changed in the last hundred year or so: two longs, short, long.

I was discussing the requirement to blow the horn 24/7 even when there is a crossing arm, flashing light, and bell, items that were rare or non-exixtent 100 years ago.

It seems pie in the sky to think that it is saving lives to add the whistle, when drivers have gone right around the arm and stopped on the tracks or idiots have walked around even when they see the train.

But hey, I appreciate the government saving me again.
