Either it may be while entering or exiting a tunnel or approaching railroads or grade crossings the driver must sound the Trains horn to alert people for their safety. Train horns are also used for acknowledging the signals given by railroad employees.

The trends of blowing train horns differ widely. Generally a train horn is blown twice, one for a short time and one for long. This is repeated in the 15 seconds up until the lead carriage has actually reached the crossing. But the way they are blown differ variously. In France, train horns are sounded only at certain hours of the day. And the horns should also be sounded while approaching other trains.

To find more about train horns, I looked through many sites. This can be bought at many places where you can find train horns, air horns etc. I had come across a site while looking for train horn kits which was really awesome. If you need to buy train horns, train horn kits, air horns etc., then this is the best site to look for.
