Opis

Approximately 25 percent of the budget for the§maintenance and renewal of railway tracks in§Switzerland more than a billion Swiss Franks is used§for the switches (a.k.a. points or turnouts) and§crossings (S&C). While in the mean time the budget§expenditure for the maintenance and renewal of plain§track is optimized with e.g. the help of decision§support systems, for S&C this optimisation stays§rather rudimentary. One of the identified causes§thereof is the lack of insight in the degradation and§deterioration process of S&C.§This study therefore combined several databases of§the Swiss Federal Railways (SBB CFF FFS). Statistical§analyses are carried out on them to retrieve the§lifetime of expectancy of complete§railway S&C and their respective components, e.g.§point rails, stock rails, frog. The expected§lifetimes are attributed to different parameters§which influence the speed of geometrical degradation§or wear of the material, e.g. total train loads§(expressed in cumulative tonnages), axle loads, the§main direction of the trains, the speed and the§quality of the foundation.
