The railroad industry has sued to block new environmental rules in California. The California Air Resources Board approved new rules in April that would b an the use of locomotives more than 23 years old beginning in 2030. The railroad industry said this would force the premature retirement of about 25,000 diesel-powered locomotives. The Association of American Railroads and the American Shortline and Regional Railroad Association filed the lawsuit on Friday. They argued the technology for zero-emission locomotives hasn't been sufficiently tested and won't be ready in time to meet the deadline. California regulators say the rules will reduce harmful pollution and prevent 3,200 premature deaths.
