From lawn and garden equipment to pharmaceutical laboratories, air compressors are used throughout the workforce to make jobs easier and improve results. However, they are essential to the modern railroad industry. Here’s a closer look at how compressed air benefits train systems and how contamination poses a serious threat.

Why Are Air Compressors Necessary to the Railroad Industry?

Many of a train's essential components operate through pneumatic systems that rely on compressed air to function. You may not realize it, but a simple train ride demonstrates compressed air at work. First, you’ll notice the gentle hissing sounds when the doors open and shut to let passengers on and off. Then, compressed air helps the brake system bring the train to a smooth and speedy stop. Finally, the suspension system, which lets the train maneuver across curves, inclines, and debris on the tracks, also depends on compressed air. 

If the compressed air systems suddenly stopped working, the doors wouldn’t be able to open automatically, keeping passengers stuck inside. Failed brakes or faulty suspension systems could lead to even more serious issues, like a collision, turbulence, or even derailing that could injure passengers and damage cargo. 

How Does Contamination Occur?

To continue working properly, railroad employees are on a constant mission to prevent the contamination of the compressed air reservoirs. However, most compressed air systems are located outside the train, vulnerable to environmental conditions. 

When the systems need more air, they pull it in from the surrounding atmosphere, which may contain many airborne contaminants. For example, there are around 140 million dirt particles in every cubic meter of the atmosphere, and the particles are so small that they pass right through the air intake filter.

 Water vapor in the atmosphere can also enter the system, condensing into water or ice when compressed. This can freeze, block, and corrode the pipes, damaging the pneumatic cylinders essential to the train’s performance.

Contamination can also be caused by the coolants and lubricants used in the neighboring systems, creating an oily residue. This can damage the air receivers and seals throughout the compressed air system and clog up the filter, resulting in further contamination.
