NedTrain, the train maintenance subsidiary of NS, has 33 Service Locations across the Netherlands. At those locations, trains are checked, repaired, washed, cleaned and stabled around the clock. Due to a higher demand for service in the upcoming years, as a result of the purchase of many new trains, the capacity of those locations is not sufficient. Based on empirical analysis, at the locations as well as to a data set of realised work orders, the expected capacity of a location is determined with a model. Using that expectation, the production of a location can be estimated. The estimation is made based on the layout of a location, the number of tracks, the presence of a washing machine, the location within the railway network and the mix of train types. The model developed gives the estimated production and the number of coaches that can be stabled at a location. The information can finally be used to check whether a location can meet the requirements. The model is accurate within a range of 30%, since all locations have different characteristics and cannot fully be defined based on the information that was available. However, the study gives a good general insight in the capabilities of the NedTrain Service Locations.
