The Aar Standard for a Spill-proof Locomotive Refueling System

The Association of American Railroads (AAR) has recently completed development of the first industry standard for a reliable, spill-proof locomotive refueling system. The Locomotive Fueling Interface Standard (LFIS) is an open, non-proprietary standard that incorporates a combination of the latest, proven refueling equipment technologies adapted for use in the railroad environment. The LFIS was developed with extensive oversight and involvement by a multi-disciplinary task force composed of individuals from railroads' mechanical, environmental, transportation and fuel purchasing groups, along with refueling equipment suppliers that supply the railroad, aircraft, mining, and cargo tank truck industries. Prototype equipment was successfully tested at the Transportation Technology Center in 1998 and then underwent field-testing on seven North American railroads at nine different locations over a period of 22 months. Following successful completion of the field-testing in 2000 the LFIS was adopted by the AAR as a recommended practice in early 2001. A cost:benefit analysis indicates that the reduction in energy and environmental costs that railroads will accrue with adoption of the LFIS will pay for the LFIS equipment in 1 to 3 years. Adoption of the LFIS is a cost-effective means for most North American railroads to prevent spillage and improve refueling performance.
