Caterpillar Company’s Progress Rail partnered with Norfolk Southern Corporation (NSC) on the first EMD GP34ECO locomotive to support yard and intermediate operations.

Currently, the locomotive is being tested to meet the United States Environmental Protection Agency’s Level 4 emissions certification requirements.

The GP34ECO is expected to achieve a 90% reduction in nitrogen oxides (NOx) emissions and provide better fuel efficiency compared to older locomotives.

Powered by a 3000 horsepower 12-710 EMD engine, the locomotive features the “first” Diesel Exhaust Fluid (DEF) / Selective Catalytic Reduction (SCR) aftertreatment system for mainline locomotive applications.

The locomotive core was assembled at NSC’s Juniata Locomotive Shop in Altoona, Pa.

NSC, in conjunction with engineering teams from Progress Rail and Caterpillar, performed the final assembly, engine and SCR aftertreatment system work.

In addition to the Cat aftertreatment control system, the locomotive also features a new crash-resistant cab and electronics.

Tom Schnautz, Vice President of Advanced Train Control at NSC, said: “In recent years, we have worked with Progress Rail to modernize more than 100 locomotives that power our road and terminal operations.

“This new locomotive is another step forward in our modernization journey, and we look forward to achieving Tier 4 emissions certification.”

For the ECO line, Progress Rail and NSC have worked together to re-engine 50 locomotives since 2008.

These new EMD ECO locomotives are expected to offer “reduced emissions, fuel economy and operational efficiency”.

Ahmed Moustehy, Vice President of Rolling Stock Sales at Progress Rail North America, said: “The design of the GP34ECO locomotive was based on the integration of a Tier 4 system to adapt to our platforms. GP and SD locomotive.

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

Later this year, these locomotives will be deployed by NSC in Harrisburg.

Additionally, the companies will work together to ensure that field trials meet final emissions certification requirements.

In May this year, Progress Rail’s subsidiary ECM and the Italian company INC won a project to modernize the signaling system on the Tirana-Durres railway line in Albania.
