New From Cummins: QST30 Repower Module

Cummins Inc. is expanding its reach into the rail market with the QST30 Tier 4-compliant switcher locomotive power module, projected to be available in the first quarter of 2022.

The QST30 locomotive power module consists of a six-cylinder diesel engine, traction alternator, SCR (selective catalyst reduction) emissions system and radiator package, with a CELECT electronic management system and other engine-related components , all on one standard skid. 

With ratings from 1,000 to 1,500 hp, the QST30 “is perfectly sized to repower switcher locomotives,” Cummins says. “Reduce fuel consumption and qualify for EPA Tier 4 government funding with this easy-to-install, drop-in solution. Cummins locomotive power modules are the ideal way to update a locomotive to clean, reliable diesel power. The success of a railroad depends on maximizing the useful life of capital-intense equipment like locomotives. Cummins is a recognized expert in repowering older units with modern engine technology and providing the installation support necessary to complete projects on-time. with minimum downtime.”

“The QST30 locomotive power module was designed as a straightforward upgrade to a modern, clean diesel engine,” the company notes “The locomotive power module will use proven SCR technology to achieve Tier 4 emissions. Cummins’ SCR technology is an effective solution that reduces NOx emissions and improves fuel economy, while being virtually maintenance-free. Cummins Rail customers prefer the company’s SCR system because, unlike EGR (exhaust gas recirculation), SCR produces much less waste heat, which reduces cooling system loads and horsepower loss. It is currently used in a range of applications to reduce site emissions for classification yards, ports and industrial sites. This solution will provide customers flexibility in their operations, and deliver an improved total cost of ownership that customers have come to expect with any Cummins solution. Cummins is proud to power rail operations by developing the next generation of rail power solutions that utilize a broad range of power innovations, emissions solutions, and connected technologies.

“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.”
