RRAB Workshop Slide and Washout Hazards: Managing Natural Risks on Railways May 1-3, 2002

Purpose of the Workshop Stimulate collaboration and the investment of resources for new developmental programs to improve the management of natural risks from slide and washout hazards on railways

Workshop Sponsors Association of Regional Railways of Canada Canadian National Railways Canadian Pacific Railway Industry Canada National Research Council Natural Resources Canada Office of Critical Infrastructure Protection and Emergency Preparedness Canada Railway Association of Canada Transport Canada VIA Rail Canada

Workshop Discussion Groups Hazard characterization Establishing the context for research Hazard monitoring and detection technologies Research needs and priorities The way ahead

Workshop Will Be Considered a Success When. . . New programs are planned, resourced, and begun within one or two years to tackle priorities identified in the workshop Significant improvements in managing natural risks from slide and washout hazards on railways are implemented and are bearing significant fruit within five years that trace their origins to the workshop

Planned Workshop Follow-Up Prepare and distribute: Full workshop proceedings Package of speaker’s overheads Prepare and circulate proposed program: Initial sounding with expert panel members Circulate results to all participants Consult with participants on proposed program Develop and implement go-forward plan: Converge on supportable program Resource the program Form technical steering group & management regime Coalesce participants and partners

Ground Hazard Research Program Risk Assessment Hazards classification system Database of incidents and case histories GIS based modeling tools for predicting events Critical weather thresholds that trigger events Field test methodologies for the Fraser Canyon and Thunder Bay rail corridors Risk Control Decision support tools for mitigating risk New technologies for monitoring and detection of events
