On Friday, June 16, 2023, the railroad industry sued to block new environmental rules in California, arguing they would force the premature retirement of about 25,000 diesel-powered locomotives across the country long before their zero-emission counterparts are ready to take their place. American federalism is struggling.
Most importantly, the California Air Resources Board regulation would have all freight trains operate in zero-emission configuration by 2035. At the end of the decade, the state is mandating the retirement of diesel locomotives 23 years or older, despite typically useful lives of over 40 years. Starting in 2030, new passenger locomotives must operate with zero emissions, with new engines for long-haul freight trains following by 2035.
The Wall Street Journal’s editorial board explained last November that while Wabtec Corp. has introduced a pioneering advance in rail technology with the launch of the world’s first battery-powered locomotive, the dream of a freight train fully powered by batteries remains elusive. The challenges of substituting diesel with batteries — primarily due to batteries’ substantial weight and volume — make it an impractical solution for long-haul trains.
As Patricia Patnode of the Competitive Enterprise Institute, which signed the aforementioned letter to the EPA, recently remarked, “Rather than abolish diesel trains, CARB should stand in awe of these marvels of energy-efficient transportation.”
