Welcome to the CTS Lunch Seminar Series
Delays in the railway system have caught a considerable attention during the last decade. As a consequence maintenance of the railway system has been a subject of political debate, both whether necessary resources are devoted to maintenance and whether the resources are efficiently used. Despite the attention, there has been a lack of studies relating planning relevant factors to railway reliability and subsequent delays in the railway system.
In this seminar a study performed by KTH, WSP and LTU is presented which was aimed at providing estimates of the effect of planning relevant factors on the track failure rate. Track failures is interesting since they are one of the more common causes of delays, 17 percent of infrastructure related delays are caused by track failures (Trafikverkets merförseningsstatistik 2013-2016). The study was restricted to Ostkustbanan between Ulriksdal and Sundsvall. The main factors studied was track age and traffic volumes (no. of scheduled trains), which both were found to have a significant and substantial effect on track failures. The effects was estimated using intensity (failure rate) models which are easy to incorporate in the so called FF-model which forecast train delays with failure intensity as input.
The seminar will be held in English.
