We’re home to the cleanest locomotive fleet in the country, Pacific Harbor Line (PHL), a “switching” line that helps assemble and disassemble trains destined for nearby railyards. The Clean Air Action Plan requires PHL to maintain the cleanest available locomotives and to limit idling to 15 minutes.

The CAAP also requires “line-haul” locomotives, which move cargo over long distances, to meet the aggressive replacement schedules under the state’s Memorandum of Understanding with the railroads and the EPA’s locomotive engine standards.
