General Information About Air Horns and Air Horn Kits
August 19, 2008
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.
Train Horn kits are popular amongst train horn enthusiasts, and can be purchased on the internet, or in specialty shops. While they look like a kids toy, these “big kid” toys do not come cheap. Many are priced in the $300 range, while a great portion of them exceed $400, and even $500.
Setting up your train horn wont be easy. It requires an air compressor and many other components. You will definitely need a tank that is greater than 20 gallons, and its crucial to make sure your tank is the right size for everything. Having an inappropriate tank can result in death, or an accident.
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.
