INFLUENCE OF MAINTENANCE WINDOWS ON THE WORKING CAPACITY OF RAILWAY ROUTE
Abstract
Purpose. The article aims to analyze the stabilization process of train movement after interruption and loss of the working capacity. Methodology. To examine the process of train movement on the route (double-track line with sorting station) in extreme conditions during the maintenance windows for capital repair of the track. During the investigation of this process time calculations of a normal motion restoration after the maintenance windows were carried out. In this process there are no organizational interventions aimed to change various coefficients. It is presented in the research in its pure form, in order to show how the system comes to equilibrium. Findings. It was found out that the major losses of working capacityduring the maintenance windows occur as a result of perturbations caused by interruptions, not the interruptions in themselves. The actual idle time in the study is about 300 train-hours. Directly because of the maintenance window it is 129 train-hours. Losses were equal to more than half of total idle time of trains caused by the maintenance windows. Originality. The authors proved the possible reduction of working capacity losses on railway direction as a result of a deliberate action on this process. Practical value. Implementation of these actions will reduce the losses of the working capacity.
