X2Rail-4 D7.2 - OTI Technology Migration

Abstract

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.
