How long are trains supposed to honk?

Federal Railroad Administration (FRA) rules require locomotive engineers to sound train horns between 15 and 20 seconds, but no more than a quarter-mile, in advance of all public grade crossings. Train horns must be sounded in a standardized pattern of two long, one short and one long blasts.

Train Drivers sound their horns when they pass a “whistle board” sign on the approach to a level crossing and this provides users with an understanding of whether or not it is safe for them to cross the railway. There are approximately 1600 level crossings around the network that are fitted with whistle boards.

The noise is supposed to be audible at 120 decibels at a distance of five metres from the track. A hundred metres off, it is still required to be 95 decibels - equivalent to a very loud lawnmower. The Noise Abatement Society has questioned the need for people 100 metres away to hear the horns.

How many decibels is a real train horn? Car horns and train horns are measured differently because of their size, a train horn is much bigger and can create more noise. Train horns are typically between 110-140 decibels in sound level! They may sound very similar but completely different levels.
