More Than 75 Tier 4 Engines Are In Operation

MINNEAPOLIS (Oct. 5, 2015) – Cummins Inc. (NYSE: CMI) broad power lineup of Tier 4-compliant engines is powering North American passenger locomotives, diesel multiple unit (DMU) railcars and switcher locomotives, delivering to the track ultra-clean diesel power with quieter operation and a lower carbon footprint.

Since 2013, when the first Tier 4 ultra-low emissions demonstration project – the NREX 2015 genset switcher built by the National Railway Equipment Co.® and powered by twin QSX15 engines providing 1200hp (895 kW) of installed power – took to the rails, more than 75 Cummins Tier 4 engines installed in rail applications have begun operating. Cummins QSX15 (600 hp/447 kW) is powering more than half of those installations. The QSX15 is being used in a variety of freight switching yards across North America. It is popular in switcher/shunter applications, where multiple-engine designs allow it to provide power-on-demand response to varying loads, resulting in increased fuel economy and a reduced carbon footprint.

Designed specifically for the rail market, Cummins horizontally packaged QSK19-R has long been the engine of choice for DMU installations around the world. Rated at 760 hp (567 kW), the QSK19-R brings fast torque response, smooth power delivery and quiet operation to a package that meets the most stringent emissions regulations in the world. In June 2015, the QSK19-R became the first Tier 4 Final-certified rail engine in passenger operation in North America, with 18 engines in routine operation in Toronto.

“Cummins welcomes the opportunity to partner with our customers to help them succeed,” said Melina Kennedy, General Manager – Global Rail and Defense Business. “We’re pleased that our ultra-clean diesel technology is helping them operate efficiently while significantly reducing emissions and improving the environment.”
