Improvement to locomotive air emissions are proposed in which event recorder data are used to profile average horsepower by throttle notch. Most of the newer locomotives have event recorders that capture data such as speed, crake pressure, generator power (kW), and throttle notch setting. However, the data itself is written in a data format that must be converted from proprietary software into PC-compatible format. Collection of statistically representative data also requires some coordination with locomotive operators as to the sample sizes, typical routes, engine type, and other locomotive characteristics. The TCEQ project representative assists in obtaining actual data from the railway operators. After performing a proof of concept for a line-haul locomotive and a yard switch locomotive, a generalized emissions model would be developed and the approach applied to the Dallas-Fort Worth nonattainment area. This work is coordinated with a parallel effort to model locomotive emissions in the Houston-Galveston area as well. The two areas on interest are coordinated for the sake of quality assurance: lessons learned in on area would be reflected in the other. The ultimate goal is to create a simple WindowsTM-based model that can estimate locomotive emissions based on imputes such as activity, age distribution, and other key variables. This is a chief reason why the Dallas and Houston projects are interlinked, since the model will be applied to both regions. Eventually such a model could be expanded to accommodate all counties in TEXAS.
