Relationship between the coordination of railway engineering works and the size of disruptions in train traffic

Abstract

Carrying out renewal or modernization works on a railway line require temporary closures of track sections. An important issue is to plan the works to minimize the traffic disruptions associated with the track closures, but simultaneously limiting the total duration of engineering works. In this paper the influence of works coordination on different track sections on the size of traffic disruptions was examined. The analysis was performed for three different schedules of renewal project on a 30-kilometer section of double-track railway line No. 353 Inowrocław -Nieszawka. The results of the study indicates that grouping works on many tracks and sections may be beneficial for low traffic intensity, while for high traffic intensity (lines with a high level of traffic capacity utilization) it results in significantly longer travel times and the need to cancel trains).
