A methodology has been developed for calculating and reporting fuel use and air pollutant emissions from railroad locomotive activity. The procedure uses automated techniques to report rail activity on a variable-sized grid system. Separate methodologies were developed for the two major types of rail activity - road or line-haul operation and activity within switch yards. The methodology for road locomotives uses a line source concept and synthesizes the rail network by a series of links connecting a system of node points within the study area. The methodology for switch yard operation uses an area source concept. Both methodologies use as a basic unit locomotive horsepower-hours and were programmed to provide an analysis of fuel use and emissions for five criteria pollutants on a grid-by-grid basis as well as for the entire study area.
