• Abstract:
  The phenomenon of flying ballast is well-documented in high-speed rail operations. Displaced ballast particles from the track bed ; may cause damage to rolling stock as well as the track infrastructure, and wayside structures close to the right of way of the railroad. ; This report provides comprehensive information to help identify potential causes and hazard consequences of ballast flight, ; determine potential risk mitigation strategies, and define the relevance of ballast flight risks in the current and planned U.S. ; passenger rail system. This report presents and discusses a conceptual risk framework, which covers factors that contribute to flying ; ballast and the consequences of flying ballast based on the location of interest. Five relevant risk factors for flying ballast are ; identified: operating speed, train design, dynamic load, track maintenance, and high winds.
