Regulations for Emissions from Locomotives
In March 2008, EPA finalized a three part program that dramatically reduces emissions from diesel locomotives of all types -- line-haul, switch, and passenger rail. The rule cuts PM emissions from these engines by as much as 90 percent and NOx emissions by as much as 80 percent when fully implemented. The standards are based on the application of high-efficiency catalytic aftertreatment technology for freshly manufactured engines built in 2015 and later.
EPA standards also apply for existing locomotives when they are remanufactured. Requirements are also in place to reduce idling for new and remanufactured locomotives.
Below is a list of all regulations related to emissions from locomotives.
