Biodiesel Passenger Rail Revenue Service Test

Amtrak, with the support of the Federal Railroad Administration, operated a P-32 passenger locomotive in revenue service for a period of 12 months on B20 biodiesel fuel, a blend of 20 percent pure biodiesel and 80 percent #2 ultra-low sulfur diesel (ULSD) fuel. The GE P-32 locomotive used in the biodiesel demonstration was a Tier 0 12-cyclinder engine built in 1991. The locomotive was operated on the Heartland Flyer route, providing passenger train service between Oklahoma City, Oklahoma, and Fort Worth, Texas. Following the in-service trial, the locomotive underwent emissions testing at the GE Transportation’s locomotive emissions test facility in Erie, Pennsylvania. The locomotive was tested for emissions according to the Federal Test Procedure outlined in 40 Code of Federal Regulations (CFR) Part 92. The test results showed that operating the P-32 passenger locomotive on B20 biodiesel blended fuel for 12 months did not adversely affect the emissions of the locomotive. In addition, tear-down inspection of four of the twelve engine power assemblies showed that B20 biodiesel fuel did not have any adverse effects on the engine components.
