Cleaner, Greener Locomotives

This article describes how the railroads, pushed by state and federal regulations, are acquiring equipment aimed at reducing emissions. Legislation in California and Texas has upped environmental air quality regulations in urban rail yards, while the U.S. Environmental Protection Agency’s Tier 3 regulations are expected to be issued shortly. Union Pacific has acquired 60 N-ViroMotive GenSet locomotives, which are powered by ultra-low emissions diesel engines. They are expected to reduce emissions by 80 percent. In addition, the railroad is using Green Goats, a diesel-battery hybrid technology, which is also expected to cut air emissions by 80 percent. The article describes how three companies are manufacturing equipment aimed at helping railroads meet government requirements.
