Prioritizing the most cost-effective way of achieving the greatest amount of clean air ought to be the rule, rather than the exception

While resources are limited, there are funds to help encourage the owners of older vehicles and equipment to make the decision to replace or repower with the latest clean technologies.
Port officials around the country are looking to reduce emissions and generate benefits for port workers and residents in adjacent communities. One rail operator in the Pacific Northwest upgraded a single old switch locomotive engine with a clean diesel model and immediately saved 19,000 gallons of fuel a year. The replacement project also reduced emissions equivalent to thousands of cars delivering significant benefits for near-port communities.
While resources are limited, there are funds to help encourage the owners of older vehicles and equipment to make the decision to replace or repower with the latest clean technologies. Nothing beats the cost effectiveness of investments in clean diesel technology when making the most of these clean air investments. This is certainly true for large applications like switch locomotives that are often in-use around the clock.
The residents near the Port of Tacoma found this out fairly quickly. The Port of Tacoma, working with the Washington State Department of Ecology secured a grant through the Diesel Emission Reduction Act along with other resources to repower an old 1950s-era switch locomotive with the latest Tier 3 clean diesel model built by Progress Rail. While the technology came with a hefty price tag, at $2 million, it immediately delivered 68,000 pounds of NOx reduced, eliminated almost 1 ton of fine particles and saved the rail operator 19,000 gallons of fuel.
Let’s put these benefits in perspective. According to the Department of Energy, a typical passenger vehicle on the road for a year consumes 480 gallons of fuel. The fuel savings from this is single switch locomotive engine replacement is equivalent to removing almost 40 cars from the road. Yet the amount of NOx reduced is equivalent to almost 22,000 cars!
A $2 million clean air investment in the latest clean diesel technology that powers a single switch locomotive can really deliver substantial emission reduction benefits for port communities.

The Toyota Prius is the iconic image of hybrid technology. Yet there are other much larger hybrids that pair advanced fuel sipping diesel engines w/ battery storage capabilities.
