Optimizing rollout strategies for migration to moving block signaling – A MINLP-based approach for on-board train integrity monitoring technology

Increasing demand on heavily-used rail corridors in line with the modernization of the signaling architecture are key drivers for migrating to modern, moving-block based train control in the European railway network. In order to maximally profit from the increase of reliability and reduction of costs associated with shifting towards full ETCS Level 3 from a network management perspective, additional requirements on the fleet management level arise. Amongst other things, if track vacancy detection equipment is to be eliminated, all trains operating on these lines need to be equipped with on-board train integrity (OTI) monitoring solutions. In order to facilitate the planning of the OTI network migration processes, a MINLP-model is proposed which allows economic optimization of OTI migration in view of fleet allocation and the removal of trackside equipment for train integrity verification within the network. The model is tested in a case-study based on a generic network abstracted from the Austrian mainline network and found to significantly enhance planning compared to heuristic migration strategies

X2Rail-4 D7.2 - OTI Technology Migration

The aim of the work was to look at the introduction of On-board train integrity (OTI) from different perspectives. Different OTI product classes are considered in their areas of application as well as the various railway market segments, with particular attention being paid to the freight transport sector, as this is particularly complex in terms of optimised wagon equipment due to single wagon traffic. To accompany the development of the on-board train integrity solutions up to TRL7, an outlook on the technology migration of the OTI is given. The work aimed at is to identify optimised migration paths for the rollout of OTI technology. To achieve this, boundary conditions are analysed in terms of surrounding migration strategies in the control and signalling of railway transport as well as migration conditions for the different market segments. Based on the technology specifications from the X2Rail-2 and X2Rail-4 projects, representative scenarios have been defined to apply the migration strategy. An optimization methodology was developed and computationally modelled and then applied to a railway network with an operating program. Based on the results of the optimization model, an economic evaluation of the different OTI migration strategies was performed. Life cycle cost analysis has been done to compare monetary effects of the different migration paths as well as the effects for different stakeholder

Gaining accurate input data for a comprehensive assessment of the railway system

To make data from different sources comparable and use it within assessment models for the railway system, several aspects have been considered in the IMPACT-2 project. Among them common definitions, aggregation level of data items as well as measurement techniques. Two examples related to the value of time and freight train definition are described in more detail

Migrationsstrategie für eine fahrzeugseitige Zugvollständigkeitskontrolle / Roll-out strategy for on-board train integrity migration

DE: Im Rahmen des Shift2Rail (S2R)-Projekts X2Rail-4 wurden Migrationsstrategien für eine Markteinführung von On-Board-Train-Integrity (OTI)-Lösungen untersucht. Als Optimierungskriterium für die Migration wurden die potenziellen Einsparungen durch den Abbau von Infrastrukturelementen und deren Betriebskosten definiert, die durch OTI obsolet werden. Dazu wurde ein Optimierungsmodell entwickelt, um vor dem Hintergrund definierter Kriterien sinnvolle Migrationsschritte zu bestimmen. Darüber hinaus wurde eine wirtschaftliche Analyse durchgeführt, um die verschiedenen Migrationspfade zu bewerten. EN: Within the Shift2Rail (S2R) project X2Rail-4 the development of on-board train integrity (OTI) solutions have been accompanied with an outlook on migration strategies for the roll-out. The optimization criterion for the migration was defined as the potential savings from the dismantling of infrastructure elements and their operating costs that become obsolete as a result of OTI. An optimisation model was developed to determine the order of roll-out and an economic analysis was performed to assess the different migration paths

Assessing Innovations in High-Speed Rail Infrastructure

With a focus on infrastructure-related innovations for HSR, this paper aims at assessing their impacts in relation to the targets of punctuality, capacity, and life cycle costs. The paper presents a hybrid assessment methodology combing different approaches to assess effects on the named KPI. This contributes to reducing the existing gap that is found in the research literature

Ökonomische Auswirkungen der Eisenbahninnovationen von Shift2Rail - The economic impacts of the railway innovations developed in Shift2Rail

The Shift2Rail initiative specifies, develops and dem onstrates new technologies in order to increase capacity and punctuality and reduce the costs of the future railway system. Due to the complexity of the railway system, the combined impacts of these technologies can lead to stronger or reduced effects. An integrated methodology using Key Performance Indicators (KPI) has therefore been developed, implemented and validated in order to estimate their overall impact. The final version of the integrated KPI assessment has been presented as a Shift2Rail cross cutting activity under the IMPACT-2 project

The KPI-Model - an integrated KPi assessment methodology to estimate the impact of different innovations in the railway sector

The Shift2Rail Joint Undertaking (S2R) has set impact targets for the future rail system. Those targets of the KPIs, calculated by comparing future KPIs in the year 2030 to baseline KPIs as of 2013, are defined in the Shift2Rail Master Plan. These include among others to double the capacity (+100%), half the life cycle costs (LCC) (-50%) and to increase punctuality by improving reliability by 50%. In order to keep track of the realisation of these targets and to measure their degree of fulfilment a quantitative KPI model has been developed. The modelling approach and implementation are discussed in this contribution

X2Rail-4 Advanced signalling and automation system - Completion of activities for enhanced automation systems, train integrity, traffic management evolution and smart object controllers - WP7 Deliverable D7.2 OTI Technology Migration (Shift2Rail)

### The deliverable is available online here: ### Link 1: https://cordis.europa.eu/project/id/881806/results ### Link 2: https://projects.shift2rail.org/s2r_ip2_n.aspx?p=x2rail-4 ### Abstract: X2Rail-4, as part of Shift2Rail IP 2, aims to drive research and development of innovative key technologies in railroad signaling, automation and monitoring. 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
