| Abstract: | Within ProRail, there are several visions about the design of the infrastructure of the railway system. On the one hand, the Infrastructure Development Department wants to reduce the asset costs and the risk of a defect on track sections and track switches that are barely used, by creating an infrastructure that is as robust as possible. Over the past three years, each track switch that has reached the end of its life-cycle, has been checked to see whether the switch should be replaced or removed. In the event that the switch track is not used very often, the switch will be removed. At this moment, the consequences for removing these track switches are not known. On the other hand, ProRail made agreements with Railway Undertakings regarding the distribution and handling of possessions. One of the agreements made is that freight trains cannot be cancelled. Therefore, ProRail wants to enable as much train traffic as possible under all circumstances. During possession, some track switches and railway sections are needed that are normally not used. At places where track switches are removed, ProRail has great difficulty in finding new diverting routes. With the information gathered from the interviews and the case study about emplacement Nijmegen an ILP model is made.The model calculates the minimal costs over the next 20 years of diverting and the asset costs after replacing and removing the track switches. The model solver is suitable to make a decision whether track switches should be replaced or removed and in which year it is the most profitable to take this decision. |
