In the past century train horns have evolved from being a simple horn, to elaborate horns with many nozzles. They serve as extremely loud devices to warn oncoming traffic and animals of the trains presence. Train horns can also serve as a signal transmitter, when conductors and employees need to pass signals between each other. A train horn consists of several pieces, but the main components are the nozzle and the diaphragm.
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.
Train horn kits can be easily purchased anywhere on the web, or through a dealer. Don't expect to get one with a kids allowance though, these special horns can cost anywhere between $200-$1000+.
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.
Train horns, personal train horns, and professional horns, can encounter some function problems. Nearly all of these will occur within the diaphragm or nozzle. Sometimes a piece could crack, or something could get stuck in there. A train horn nozzle makes a great home for birds, which could also cause problems with your horn. To keep it in great condition, regular maintenance is necessary. Its important to polish and clean your train horn, and remove any debris from the inner nozzle and diaphragm. There are several companies that offer their repair services for a small fee. However, different horns require different maintenance due to the way they were produced. This is also based on age and rarity.

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.
