To Our Customers,
Union Pacific's most powerful snow-removal machine, the rotary snow plow, was in full operation this past weekend during the third snowiest winter in the Sierras in recorded history. The plow cut through snow that reached depths of 13 feet, across 14 miles near the Donner Pass. The railroad's first and second lines of defense against snowstorms – flangers and spreaders – were unable to keep the tracks clear due to the depth of snow walls, so the rotary was required to clear large amounts of snow in a timely manner.
We have three one-of-a-kind rotary snow plows to use as needed during winter months. Union Pacific's plows were originally built in the 1920s and operated by steam, then overhauled and converted to diesel electric in the 1950s. In 2012, we made the first major makeover in more than 60 years to one rotary plow enhancing its productivity, reliability and power. We plan to enhance another rotary plow in 2017.
Union Pacific is working diligently during the winter months to keep our lines cleared of snow and ready for your business.
