ABSTRACT (Maximum 200 words) Section 404 of the Passenger Rail Investment and Improvement Act (PRIIA), 2008, mandated that the Federal Railroad Administration (FRA) undertake a Locomotive Biofuel Study to investigate the feasibility of using biofuel blends as locomotive engine fuel. This report summarizes three research initiatives undertaken by FRA to assess the viability of biodiesel as an alternative fuel for locomotives. The first initiative consisted of using a 20 percent blend of biodiesel in a passenger locomotive in revenue service to study air emissions and engine wear. The second initiative measured the emissions of Tier 1+ and Tier 2 locomotives operating on 5 percent and 20 percent blends of biodiesel, respectively. Those emissions were compared with those generated by conventional diesel fuel. The third initiative investigated the availability of biodiesel, rail yard and revenue service engine performance and emissions on various blends of biodiesel, as well as the practicability of using an alternative method to measure those emissions. The results from these research initiatives show that while it may be feasible to use biodiesel in blends of up to 20 percent in locomotive engines and reveal some impact on emissions, additional research is needed to understand the long term effects of high blends of biodiesel on locomotive engine components. 14.

FRA would especially like to thank Roy Deitchman (Retired) and Wade Smith of Amtrak. • Steve G. Fritz of the Southwest Research Institute for conducting the Locomotive Emissions of Various Blends of Biodiesel study, as well as providing valuable insight into the effects of biodiesel on locomotive engines. Mr. Fritz also supports FRA and the railroad industry in collecting and analyzing defects of locomotive engine components from engines that used biodiesel. This effort supports increased understanding of engine durability issues. • H. Christopher Frey of North Carolina State University for conducting the Locomotive Biofuel Study that investigated costs, availability of biodiesel, and alternative methods to measure emissions of the engine in dynamic operations. • FRA would also like to thank Manuch Nickanjam for his leadership of the SAE TC7 Biodiesel in Railroad Applications industry forum. The support of the SAE TC7 and Manuch enabled FRA and the railroad industry to candidly discuss the effects of biodiesel in locomotive engines and to identify a path forward for a qualitative analysis of biodiesel on locomotive engine durability. The support of these individuals and organizations allowed FRA to gain valuable knowledge about the viability of biodiesel as an alternative fuel. iii Contents Executive Summary ........................................................................................................................ 1 1.
