X2Rail-4 Work Package 7 (WP7) develops an innovative prototype on-board train integrity system, which is capable of monitoring train integrity with wired or wireless communication. There is no need for deployment of any fixed trackside equipment. One of the main objectives of this work package is to investigate possible migration scenarios for a roll-out of OTI systems, including an economic analysis. The aim of the studies on migration for OTI is to show under which conditions the new technology should be introduced to be implemented as optimally as possible for the overall railway system and the stakeholders acting in this ecosystem. The analysis was carried out in parallel with the development of the three OTI product classes developed within X2Rail-2 and X2Rail-4 and considers examples of their possible applications in the various market segments. For freight transport in particular, attention was drawn to taking appropriate account of the complexity arising from the distinction between block trains and single wagonload traffic. The deliverable thus addresses the task described in the contractual documents. It should be noted that the application had to be for generic example scenarios. In the context of this project, the focus was purely on the OTI. The consideration of additional boundary conditions (arising e.g. from ETCS, DAC, ...) has to be done in the context of the real roll-out under the then prevailing conditions. The developed methodology provides a good starting point for this. The optimization criterion for the migration was defined as the saving potential resulting from the removal of axle counters and track circuits that are no longer required. The optimization potential lies in the fact that, if trains are equipped with OTI in an optimised manner, track sections can dispense with axle counters and track circuits as early as possible without restricting the operating program. By saving these field elements, their operating costs and potential reinvestments are eliminated, so that an optimum can be achieved overall for the entire system. As part of an economic analysis, the effects were differentiated for infrastructure manager and wagon owner. Methodologically, an optimization model was newly developed for this project, which deals with the optimization criterion and the defined constraints and performs a mathematical optimization of the possible migration paths. This model was applied prototypically for the first time to a generic network with an operating program. The results show the potential of an optimization under the given input variables. For subsequent projects, the developed computational model provides a tool that can be used to determine optimised migration strategies given the appropriate data input. Likewise, there is potential for scientific follow-up to further develop and optimize the tool on the one hand and to make comparisons between the optimised results and, for example, non-optimised (random) migration processes or manually performed optimizations on the other hand. In this way, for example, migration plans drawn up with human expertise could be reviewed and compared to computational results. ### X2Rail-4, Advanced signalling and automation system - Completion of activities for enhanced automation systems, train integrity, traffic management evolution and smart object controllers; project funded from the European Union's Horizon 2020 research and innovation programme (IP 2 - Advanced Traffic Management & Control Systems)
