I have 26 years of experience, and specialize in the field of railroad and rapid transit accident investigation and report writing with specific knowledge in the areas of railroad equipment, operations and train handling and track structure and maintenance. I have published on such topics as freight train mountain grade braking, FRA steam locomotive regulation update and continuous welded rail issues. I have testified on grade crossing safety, event recorder readout and track-train dynamics. In over 22 years at the National Transportation Safety Board, I originated 157 adopted recommendations that have made the railroad and rapid transit industries safer.
