Cummins said the QST30 locomotive power module will incorporate an engine, alternator, selective catalyst reduction (SCR) emissions system and radiator package and other engine related components, all packaged on one standard skid.

With ratings from 1000 to 1,500 hp, the QST30 is perfectly sized to repower switcher locomotives, the company said, while 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.”

The QST30 locomotive power module incorporates the company’s SCR technology to achieve Tier 4 emissions regulations. Cummins said its rail customers prefer SCR because unlike exhaust gas recirculation (EGR), SCR produces less waste heat, which reduces cooling system loads and horsepower loss.

The technology is currently used in a range of applications to reduce site emissions for switch yards, ports, and industrial sites.

Cummins said the QST30 locomotive power module will be available in the first quarter of 2022.
