Powered by a 3,000hp 12-710 EMD engine, the GP34ECO utilizes the “first Diesel Exhaust Fluid (DEF) / Selective Catalytic Reduction (SCR) aftertreatment system for mainline locomotive applications,” according to Norfolk Southern and Progress Rail collaborators.

Norfolk Southern (NS) and Progress Rail, a Caterpillar company, have teamed up on the first GP34ECO locomotive for yard and intermediate service; it is currently undergoing testing to meet the U.S. Environmental Protection Agency’s Level 4 emissions certification requirements, the companies reported on September 30.

Powered by a 3000hp 12-710 EMD engine, the GP34ECO utilizes the “first Diesel Exhaust Fluid (DEF) / Selective Catalytic Reduction (SCR) aftertreatment system for mainline locomotive applications,” they said. declared NS and Progress Rail. The unit also offers a new impact resistant cab and new cab electronics.

Since 2008, NS and Progress Rail have re-engineered 50 locomotives specifically for the ECO line. “The new and improved EMD ECO locomotives offer lower emissions, fuel savings and operational efficiency,” they said. “Each of these units can replace two older, less efficient locomotives. “

“The design of the GP34ECO locomotive was based on the integration of a Tier 4 system intended to adapt to our GP and SD locomotive platforms,” said Ahmed Moustehy, vice president of rolling stock sales in North America for Progress Rail.

A 90% reduction in nitrogen oxides (NOx) emissions and “significantly higher fuel efficiency” are achieved with the GP34ECO, according to NS and Progress Rail.

The unit is expected to enter intermediate service in Harrisburg, Pa. Later this year, and NS will work with Progress Rail “to ensure field tests meet final emissions certification requirements.”

NS assembled the locomotive core at its Juniata Locomotive Shop in Altoona, Pennsylvania. The Class I railway, in conjunction with engineering teams from Progress Rail and Caterpillar, performed the final assembly, engine and SCR aftertreatment system work.

“We have a long tradition of modernizing our locomotive fleet, strengthening our day-to-day operations while pursuing our sustainability goals,” said Tom Schnautz, vice president of forward train control for Nova Scotia. “Over the past few years, we have worked with Progress Rail to modernize more than 100 locomotives that power our highway and terminal operations. This new locomotive is another step forward in our modernization journey, and we look forward to achieving Tier 4 emissions certification. ”

Moustehy added, “As part of our commitment to sustainability, we plan to work with our clients to identify opportunities for other ECO programs in the future. “
