Cummins prepares for implementation of Tier 4 emissions regulations

Ben Treadwell - 16 September 2014

Cummins Inc. has prepared for the upcoming implementation of U.S. Environmental Protection Agency (EPA) Tier 4 emissions regulations on January 1st, 2015, by ordering over 100 engine installations for passenger trains, diesel multiple units (DMUs), and switcher locomotives.

In an interview with RailwayAge.com, Randy Nelson, Manager of Rail Business Development at Cummins, said: 'Our Tier 4 rail vehicles on order extend from 1,200 hp (895 kW) up to 5,400 hp (4,027 kW) of installed power, featuring the latest generation of Cummins 15-liter to 95-liter engines with integrated Selective Catalytic Reduction (SCR) exhaust after treatment. The installations include both single- and innovative multi-engine designs with a power-on-demand capability to significantly reduce fuel consumption and carbon emissions."

The first locomotives using the new Tier 4 standards in North America are set to begin service in January 2015 on the Union Pearson Express, an air-rail link currently under construction from downtown Toronto to Toronto Pearson International Airport. Similar DMU's will also be in operation at Sonoma-Marin Area Rail Transit, north of San Francisco. These two projects will be the first modern DMUs in operation in North America.
