At Chicago’s LaSalle Street commuter rail station, CSX chief executive Michael Ward—in town to accept Railway Age’s Railroader of the Year Award (and sporting a green tie)—unveiled four National Railway Equipment Co.-built, EPA Tier II-compliant, 2,100-hp 3GS21B-DE N-ViroMotive GenSet locomotives (sporting CSX’s blue and gold livery).
These units, each equipped with three 700-hp Cummins engines and Cattron-Theimig remote control, are assigned to CSX’s Barr Yard Riverdale, Ill., just outside Chicago. The locomotives were acquired through a public-private partnership, with 80% funding from a CMAQ (Congestion Mitigation and Air Quality) grant and 20% from CSX. They join four other GenSets operating in CSX's Rougemere Yard, Dearborn, Mich.
These GenSets are retrofits of older locomotive technology. Essentially, they’re a total rebuild of an EMD GP38. Equipped with three computer-managed 700-hp engine-generator sets, they reduce NOx and PM (particulate matter) emissions by up to 80% and CO2 by up to 50%.
