Train horns are a common communication and warning device. They have been in use since the mid 1900s, and are still used to this day. Their intended purpose is to blare a loud noise that will startle any people or animals that are on or near the tracks. Train horns have important functions, and the two pieces that make them that way are the diaphragm and the nozzle.

Train horns function by using compressed air, on a scale from 125-140 pounds per square inch. Oscillation is the flow of air throughout the horn, and helps to produce the sound that we hear. Air application to the horn results in a vibration and waves of air flow outwards creating a loud whistling noise. The shape, and size determine the frequency and pitch of the horns noise. When train horns were first invented they were operated by using a pull cord or lever. Currently train horns are used by simple pressing a button. Train horns are not used solely for trains, in recent times they have become popular for use on trucks, SUVs, and other large vehicles. Many people use them on water craft for warning signals as well. Some people even collect them for their sentimental value, and their beauty. Suburban areas have banned uses of train horns in certain areas. They tend to disrupt quiet areas and anger the local citizens.

Are you interested in buying a Train Horn or Train Horn Kit? You better be ready to dish out the cold hard cash for it. They range from the low $200 to over $1000! Some even come in gold, and gold plated.

When installing your train horn its important to take the measurements and placement into consideration. An air compressor tank that is too small will not be sufficient to fuel your horn, and one that is too large could cause some serious problems with the horns and possibly a fatality. Many companies recommend that you use a 20 gallon tank or larger, depending on your horns requirements.

When repairing your train horn keep the size, manufacturer, and age in mind. Older train horns that are rare, need to be cared for in a delicate manner. One mistake can ruin their value significantly. Professionals that restore train horns will fix yours up for a small fee. Train horns of all types are subject to abnormalities at some point in time. The two major components of a train horn are hollow, so there is plenty of open space for all sorts of things to collect. Sometimes the most unexpected things can appear inside, and cause sound problems. A danger is also posed here, because an animal could have made its home inside.

Closing Comments

In conclusion, Train Horns are just as necessary today as they were 50 years ago. They are enjoyable for collectors, and also provide safety measures.
