The locomotives, originally built by MotivePower about five years ago, will be repowered with new engines that meet U.S. Environmental Protection Agency Tier 4 emission standards. They include technology that reduces diesel particulate emissions by about 85% and NOx emissions by about 75%, compared with the current models.
"These will be the first North American passenger locomotives to be equipped with Tier 4 technology," said Wabtec President and CEO Albert J. Neupaver. "We believe MotivePower is well positioned to participate further in this market by offering similar environmental upgrades to existing diesel-electric commuter locomotives throughout North America as the new standards are phased in over the next several years."
