Transportation Safety Board
Underlying Factors in Subgrade Failures
IRSC Conference
Tokyo, November 2002
TSB Mandate
Advance transportation safety by:
– Conducting independent investigations
– Making findings as to causes, contributing factors and identify safety deficiencies
– Making recommendations to reduce or eliminate the safety deficiencies
Recommendations
Nakina (1992) & Conrad (1997)
– Identification of sites susceptible to slope instability
– Review of current roadbed design criteria
– Adequacy of existing drainage systems
– Systems for monitoring roadbed integrity

The way ahead
Workshop Will Be Considered aSuccess When. . .
New programs are planned, resourced, and begun within one or two years to tacklepriorities 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-UpPrepare and distribute:
