St. Louis Metro
The Fleet Test and Evaluation and Nonpetroleum Based Fuels teams worked with the National Biodiesel Board and St. Louis Metro (Metro) to test and evaluate the extended in-use performance of B20 in transit buses. Fifteen 40-foot, model-year 2002 transit buses manufactured by Gillig and equipped with Cummins ISM engines were evaluated in this project; eight operated on B20, while seven ran on ultra-low sulfur diesel.
Located in St. Louis, Missouri, Metro maintains a fleet of 433 buses, 77 light-rail vehicles, and 125 paratransit vans. In 2005, Metro transported more than 4.65 million passengers throughout the St. Louis metropolitan area.
The results of this 12-month final report are featured in St. Louis Metro Biodiesel (B20) Transit Bus Evaluation.
