The performance of railway engineering works involves the need to temporarily stop the train traffic along tracks covered by works. Track closures can be the reason for cancellation of selected trains, prolonging the travel time and changing the timetable. The issue of planning railway works in so-called operational closures in a short, weekly time span with minimized rail traffic disruptions is analysed in this paper. An optimization model has been presented, solution of which for a section of a railway line with a length of several kilometers and traffic of several hundred trains can be obtained in no more than a dozen or so minutes. The case study for maintenance works on the railway line No. 353 in Poland, on the section Poznań Wschód - Pobiedziska is presented.
