Cummins Develops Option to Help Switcher Locomotives Reduce Emissions

Cummins Inc. is expanding its product offerings in the rail market segment with the addition of the clean and reliable QST30 Tier 4 locomotive power module.

The power module is perfectly sized to repower switcher locomotives, providing reduced fuel consumption, which translates to a reduction in greenhouse gases in addition to a lower cost of ownership.

“Cummins is excited to offer the QST30 Tier 4 power module for locomotive repowers,” said Regina Barringer, Global General Manager, Rail and Defense. “Our customers will benefit from performance and emissions improvements with this drop-in solution. Cummins’ QST30 power module makes it easy for customers to modernize their rail assets to get the most value out of their equipment.”

Cummins locomotive power modules are ideal to update a locomotive to clean, reliable diesel power. The success of a railroad depends on maximizing the useful life of capital-intensive equipment like locomotives. Cummins is a recognized expert in repowering older units with modern engine technology and the installation support necessary to complete projects on-time with minimum downtime.

Advanced diesel engines have made significant strides not only in reducing carbon emissions, but emissions that are key ingredients in smog in urban areas.

The QST30 locomotive power module uses proven SCR technology to achieve Tier 4 emissions regulations. Cummins’ SCR technology reduces nitrous oxide (NOx) emissions and improves fuel economy.

Cummins Rail customers prefer the company’s SCR system because, unlike exhaust gas recirculation (EGR), SCR produces much less waste heat, which reduces cooling system loads and horsepower loss.

PROVEN TECHNOLOGY

The technology is currently used in a range of applications to reduce site emissions for switch yards, ports, and industrial sites. It provides customers flexibility in their operations and consistently delivers an improved total cost of ownership that customers have come to expect with any Cummins solution.

Customers can expect the QST30 locomotive power module to be available in Q1 of 2022.
