Infrastructure
maintenance has a lot
to do with the quality
of service the customer
receives. Combined
with the maintenance
on rolling stock, it
guarantees the safety
and dependability of
train operations. At
the present time, rail
maintenance is based
on the skills of the
personnel, fault-detection
systems and
the calculation of total
tonnage that has
travelled over the rail.
SNCF Research wants to
rationalise the approach
to maintenance by
applying statistical
analysis to the factors
that contribute to rail
rupture. These factors
include rail weight
and profile, the route,
train speeds and
environmental
conditions, among
others. These
parameters were
identified and quantified
recently in university
studies conducted in
close co-operation with
SNCF’s Research and
Rail Maintenance
Departments.
