CN is also working with EMD, Westport Innovations Inc. and Gaz Métro Transport Solutions on a longer term project to explore a state-of-the-art natural gas railway engine and a standardized railway tender. The CN-led group expects to conduct engine laboratory tests in 2013 and to roll out the prototype main-line locomotives for road tests in 2014.
CN will provide two 4,300-horsepower SD70M-2 EMD locomotives for the test program. EMD, in addition to the engine conversion, will supply technical expertise to integrate the natural gas engine, related components and controls into the locomotive, including Westport™ high-pressure direct injection (HPDI) technology. Gaz Métro will develop natural gas liquefaction requirements and distribution systems. As part of the project, Westport secured a funding commitment of C$2.3 million from the Canadian government.
