David McKain
Consultant to Transport Energy Strategies
David McKain holds an M.S. in Mechanical Engineering from West Virginia University. He currently directs and executes EPA certification testing of locomotives for Norfolk Southern and the American Association of Railroads. His professional responsibilities include assuring that data collection equipment, test conditions and procedures, data post-processing and reporting comply with EPA test regulations. He has extensive experience interpreting, handling, manipulating and analyzing large datasets and extracting information from publicly available datasets and reports. During his twenty five year professional career he has directed and/or participated in numerous projects related to emissions and performance heavy-duty engines, vehicles, fuels and aftertreatment systems and has authored or co-authored numerous research articles. He has broad experience with fuel chemistry having conducted engine emissions and performance testing with both liquid and gaseous fuels including novel work with fuel blending and engine knock as well as comparative testing for federal and state regulatory certification. Mr. McKain currently works with the West Virginia University Research Corporation as a supervisory engineer.
