ARB Semi-Annual Railyard Inspection Reports



Contacts for Excessive Idling and Smoking Locomotives Complaints

You can use the following options to report excessive idling or smoking locomotives.

BNSF Railway 1-800-832-5452
Union Pacific Railroad 1-888-877-7267



Proposed Commitments

To determine whether UP and BNSF have met the commitments diesel PM emission reduction levels, ARB will review the comprehensive emission inventories and interim emission inventories in relation to information collected by ARB staff.  ARB will conduct semi-annual railyard inspections (see above), which will also be augmented by ARB photographic tracking and field surveys of railyard switch and medium horsepower locomotives.  In addition, ARB staff will use the annual locomotive NOx fleet average agreement submittals to verify the number and tier of interstate line haul locomotives operating within the South Coast Air Basin.
