Fairmount Santrol has deployed a Railserve Leaf Gen-Set locomotive at its Roff, Oklahoma, resin-coating plants. The locomotive uses 50 percent less diesel fuel in less time to move six times the number of railcars around the two Roff property plants, while reducing nitrogen oxide (NOx) emissions by 84 percent and improving air quality.
The new locomotive is the second acquired by Fairmount Santrol. In 2012, the company purchased a Railserve Leaf for switching operations at one of its Wisconsin mines.
The Cummins QSX-15 engine that powers the Leaf is EPA certified Tier 3.
The EPA’s Tier 4 emission standards, which take effect in 2015 and call for the single largest emission reduction in the tiered program’s timeline, require manufacturers to lower locomotive diesel engines’ particulate emissions by 70 percent and NOx by 76 percent, compared to engines first introduced in 2005.
