COLUMBUS, Ind. (September 14, 2012) -
Cummins Inc. (NYSE: CMI) will power the first fleet of commuter locomotives in North America meeting EPA Tier 4 ultra-low emissions regulations with a twin-engine QSK60 installation delivering 5,400 hp (4027 kW) output with an integrated Selective Catalytic Reduction (SCR) aftertreatment system. The innovative twin-engine QSK60 repower is specified for a fleet of MP40 locomotives operated by GO Transit in the Greater Toronto and Hamilton Area, scheduled to play a key transportation role at the 17th Pan American Games taking place in July 2015.
The MP40 commuter locomotives manufactured by Motive Power Inc. are ideally suited to the mass transit, high frequency routes operated by GO Transit, and are capable of pulling up to 12-car double-deck sets with capacity for over 300-passengers. The QSK60 twin-engine configuration offers a highly flexible power-on-demand advantage for the MP40 locomotive, resulting in major fuel savings and a corresponding reduction in CO2 emissions.
“The Tier 4 QSK60 engine offers an ideal clean power solution for twin-engine installations with a space efficient envelope and exceptional durability. We anticipate that the demand for these highly efficient repowers will continue to grow, responding to an increasing focus on reducing emissions and increasing fuel economy by rail operators,” said Randy Nelson, Cummins Rail Marketing Director.
The 16-cylinder, 60-liter QSK60 twin-engine installation is design-integrated with an SCR aftertreatment system designed by Cummins to replace the exhaust silencers in the locomotive. The advanced engine combustion and the SCR system work together to achieve exceptionally clean and quiet locomotive operations while producing no visible smoke.
The QSK60 engine meets the very low levels of 0.04 g/kW-hr Particulate Matter (PM) and 1.7 g/kW-hr for Oxides of Nitrogen (NOx) emissions required to meet U.S. Environmental Protection Agency Tier 4 regulations taking effect Jan.1 2015 for North American locomotives. This represents a 75% reduction in NOx and an 85% reduction in PM. In terms of NOx and PM emissions specifically, the output of one Tier 2 locomotive is comparable to five Tier 4 locomotives.
