The railway sector in the Netherlands is facing challenges in demand for higher capacity, aging safety systems, European demands to realize interoperability, implementation of modern rolling stock with less shunting performances and the need to standardize technologies. These challenges raise the question whether the Dutch train detection system, which detects the presence and absence of trains in railway sections, is prepared for these challenges and can ensure high performance levels in the light of these future developments. Through interviews with experts from the railway sector insights were gained in evaluation criteria for future train detection systems and (together with literature study and desk research) performance of current train detection systems was analyzed. A Multi Criteria Analysis gave further insight in what alternatives were possible solutions for these challenges . Adaptive Policy Making was applied to setup a first design of a migration strategy, which considers unknown events in the future to unfold and inevitability affect the implementation of the desired policy. Furthermore, a stakeholders’ analysis gave insights in how to engage with stakeholders during this process. From above mentioned findings it is concluded that the current train detection system shows good performance levels, but for how long? Experts from the railway sector have an almost unanimous consensus that a least there is an urgency to decide now about train detection strategy for the long-term. It is suggested to further develop and implement the proposed adaptive migration strategy.
