They modeled one line from the network that they were interested in. The model simulated all the trains for the whole day. The AnyLogic simulation model was much better than the visualization of the railway network that was previously used by Netherlands Railways. The model was interactive, easy to use, and explainable to the end users. They integrated AnyLogic with a lot of other predictive tools. Engineers could develop a concept rapidly, spending less than one week on a new model. Using AnyLogic, they made macroscopic, conceptual models.
Usually, they simplified problems into the following: a broken train blocked the track, or the track was blocked and no trains were allowed to pass. For example, a high-voltage cable dropped on the railway track, and it took half a year to repair it. Disruptions could be cows on the track, doors not closing, or power failures. There was no day when all trains were on time with the right crew and the right rolling stock. They are hard to predict, but happen every day. Netherlands Railways previously used only microscopic, very detailed simulations, but it was hard to work with them.ĭisruptions were one of the main problems for Netherlands Railways. Netherlands Railways engineers needed to test the procurement and introduction of the new rolling stock and innovations such as self-driving trains and the digital train protection system. Also, they could not cause disruptions on railway lines because it would destroy the entire country. They could not try out many innovations in real life. Netherlands Railways engineers used virtual testing of innovations. The railways run ‘from Utrecht to Tibet’ and spread out for 6,830 kilometers. Every year, 9 million people travel on blue and yellow trains. Their revenue for 2018 was 5.926 million euros. Netherlands Railways are one of the busiest rail networks in the world after Switzerland.
