Dropping temperatures can slow projects of all kinds. Many industries experience low productivity and profits during the winter months. However, the railroad industry is one that must continue the same productivity year round—regardless of weather.
Winter’s Impact on the Railroad
Railroads are an important industry for the American economy (and for many economies worldwide). When you consider how much freight passes through locomotives every year, you can account for a significant amount of the goods and supplies that many companies rely on. The railroad industry simply can’t afford winter downtime.
Cold weather can stop many different types of fair-weather operations, but the railroad isn’t one of them; there is too much at stake. Yet, despite the continuity demanded of our railways, cold temperatures can drastically affect the materials and equipment needed to keep trains moving.
Freezing conditions cause a wide variety of operational problems for the railroad industry. Let’s take a closer look at a few of these winter woes.
Frozen Track Switches
As ice and snow buildup along the track, switches become points of vulnerability. A frozen switch will bring the railroad to a halt or can catastrophically send trains in the wrong direction entirely. Railroad companies most commonly use electric and gas powered heaters to melt, and drive away ice and snow from these switches.
Reduced Gas Pressure
The gas powered heating systems mentioned above, rely upon on-site gas storage cylinders filled with either propane or natural gas. When temperatures drop below freezing, the gas pressure within the tanks also falls. A drop in pressure will restrict gas flow to such a degree that you can no longer reliably power your critical heaters.
Ice Blockages and Build-up
Wintertime ice build up can happen in a number of different ways. Burst pipes, repeated freeze-thaw cycles, freezing rain, and ice storms can cause ice to build up on any and all vertical or horizontal surfaces. Railroad sensors, detectors, and other pieces of equipment need to remain unobstructed at all times. Wayside, defect, and drag detectors placed along the track can discover problems with the train as it passes overhead. Ice build up prevents these detectors from functioning and compromises safety along the entire track. Ice build up can also cause malfunctions for crossing gates, safety signals, and other pieces of equipment up and down the track.
Subterranean frost can cause the ground to heave, swell, then sink as it freezes and thaws. For railroads, this can create a serious problem. Ground heave can dislodge and break apart sections of track, making them unusable until they are repaired. In some locations, because ground water can freeze several feet below the surface, these repairs produce a lot of costly downtime. Excavating, leveling, and grading frozen ground is extremely time consuming and difficult.
Unworkable Repair Materials
Rail companies use multiple methods to lubricate their tracks and wheels and prevent destructive friction. Some use wayside lubrication stations placed next to the track right before a curve or switch. These storage containers are activated when a train passes over a sensor, and then lubricant is sprayed over the wheels as they pass. Train cars can also be outfitted with on-board greasers that will trigger lubrication before entering a curve or switch. Some rail companies also use mobile greasing trucks, with lubricant storage mounted at the back, that can easily get around to apply lubrication or re-fill wayside grease storage.
Stored liquids become thicker and more viscous as temperatures drop. Storage drums, buckets, and tanks that produce an easy flow of grease during the summer months can become completely unusable during cold conditions. In general, highly viscous fluids are extremely difficult to pump, spray, spread and work with.
