We don’t normally think of railways and locomotives as an obvious application for compressed air technology.
One reason is that rail transportation is a challenging environment for air compressors and compressed air systems. The equipment is often squeezed into compact, hard-to-reach spaces. It is exposed to weather extremes, including the elements and varying temperatures. It is often subject to dirt, dust and debris. Not to mention shaking, shock and vibration. On top of that, there’s constant pressure to keep the trains running with little time for maintenance. And concerns about lifecycle costs.
But, as in many industries, you’ll find air compressors and compressed air systems “all aboard” in train and rail operations. They’re not only on the trains themselves, but also back at the station, supporting some critical functions.
Let’s take a closer look.
Compressors power several different railway functions:
Compressed air systems help pantographs remain in contact with the catenary lines above the tracks, supplying electrical power to the train.
Compressed air systems play a significant part in railway operations as well. Key elements include:
Back at the station, compressed air systems play an essential role, helping with pneumatic controls and a variety of maintenance tasks.
One little-recognized application of compressed air is its use to pressurize railway tank cars carrying oil and chemical products.
Pressurization performs the following functions:
In short, tank pressurization is a crucial safety measure that ensures product integrity, reduces the risk of vaporization and loss, prevents contamination and leaks and enhances emergency response capabilities.
Compressed air systems help keep railway tank cars pressurized, helping ensure their safety during transit.
Because of their sometimes-hazardous cargo and impact, the U.S. Department of Transportation has issued specifications for pressurized railroad tank cars.
Most railway applications need high-quality air. Painting, for instance, needs high-quality air free of moisture and pulsations that sometimes come from reciprocating compressors. And tank-car pressurization requires air free of moisture and contaminants.
And as mentioned, compressed air systems on trains often operate in a hostile environment, subjected to the elements and temperature extremes. Bombarded with dirt, dust and debris.
As a result, compressed air systems need efficient and reliable filtering systems, dryers and coolers to stay on track.
