Abstract [en]

Switches and crossings (S&Cs) failure statistics for the UK rail industry are investigated for the various types of S&C in the network with varying geometry, switch length and allowable speed limit. The analysis is based on recorded delay and failure rectification costs for a single (financial) year. The overall cumulative delay cost and the cost per unit have been included in the investigation. Wear has been shown to be the common damage type in all lengths of S&C in terms of delays and rectifications costs, since one of the rectification procedures for such failure type is replacement of the asset. Mid speed switches, such as C length and D length switches, have high industrial relevance due to the high costs in terms of failure delays. The normalised delay per total population showed a highest delay cost for the high speed G+ length switch.
