General Information About Air Horns and Air Horn Kits
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 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 a train horn is a complicated process, and also requires a bit of precision. Importance is placed upon choosing the correct air compressor to generate the sound, and the right placement. A mistake in any of these categories can be lethal, and is highly dangerous. It is advisable to have an air compressor of 20 gallons or higher. This allows for a surplus, and keeps you from running back and forth to a gas station to fill it up.
Personal train horns, and horns used on trains are bound to have functionality conflicts. Since the two main pieces are hollow, they make great homes for small creatures and insects. This interference will greatly impact the sound that is produced from your horn. While regular maintenance is necessary, it is also advisable to get your train horn repaired at a professional place if necessary. Collectible horns and everyday use horns have different repair and maintenance requirements, so make sure you know what you are doing before attempting anything on your own. For a fee you can see an antique dealer, or a professional train horn tuner to get your horn in perfect shape again.
