GE Transportation is showing off a next-generation diesel locomotive design that aims to cut emissions by up to 70 percent.
The new Evolution Series train, used for heavy-haul freight operations, is the first one to meet Tier 4 emission standards that have been outlined by the U.S. Environmental Protection Agency. Those standards, which go into effect in 2015, require companies making diesel train engines to cut the level of particulate emissions that they emit by 70 percent and reduce nitrogen oxide by 75 percent, compared with 2005 technology.
GE has sold more than 5,000 early editions of the Evolution locomotives.
It has invested close to $600 million over the past eight years in the new technology, which it plans to build in Erie, Pa., and Fort Worth, Texas. The big benefit of GE's approach is that it does not require an additive that will require fueling stations to be built alongside rail infrastructure.
The current political climate does not bode well for emissions regulations, though, so hopefully GE will ultimately be able to justify that investment.
