The Environmental Protection Agency’s newest emissions standards set into law in 2004, which took effect in 2010, limited the level of emissions that locomotives are allowed to produce. For the most part, these standards have been verified in the laboratory and not while the locomotives were in actual use. My research looked at the emissions from these locomotives in-use, under normal operating conditions. The measurements took place on two Pierce County bridges that are above operating train tracks. A remote sensing device (the FEAT) was used to look at locomotive emissions of CO, HC, NO, NO2, SO2, and NH3. In addition to determining average emission factors for these pollutants differences in emissions among service type, speed, and model year will be determined upon further data analysis. The data will provide a resource for in-use emissions data from locomotives. Such a resource will provide important information on current locomotives that is currently kept private due to the industry’s competitiveness.
