InBridge4EU is a research project funded by the Europe’s Rail Joint Undertaking, whose objective is to “deliver a high capacity integrated European railway network by eliminating barriers to interoperability and providing solutions for full integration, covering traffic management, vehicles, infrastructure and services, aiming to achieve faster uptake and deployment of projects and innovations. That should exploit the huge potential for digitalisation and automation to reduce rail’s costs, increase its capacity and enhance its flexibility and reliability, and should be based upon a solid reference functional system architecture shared by the sector, in coordination with the European Union Agency for Railways.”
In this regard, the general aim of the partnership will be to ensure a fast transition to more attractive, user-friendly, competitive, affordable, easy to maintain, efficient and sustainable European rail system, integrated into the wider mobility system. EU-Rail will support the development of a strong and globally competitive European rail industry while contributing towards the achievement of the Single European Railway Area (SERA).
InBridge4EU addresses the points specified in the ERA Technical Note on work needed for closing TSI open points on bridge dynamics. This document aims to “to close TSI open points on Bridge dynamics, necessary investigations to formulate a European dynamic interface between railway bridges and rolling stock are needed. New methods must be further developed and should be compatible with the existing regulations in TSI INF, TSI RST, TSI OPE, EN15528 and EN1991-2 with a particular focus on the interface with existing infrastructure. (…) further research to evaluate the dynamic behaviour of the bridges during train passage using the DER method and the time step integration calculation (TSC) for a set of representative bridges together with the following representative train data is needed:
Considering previous research in this area (e.g. the DZSF funded project Bridge dynamic: Dynamic load model; the S2R funded projects IN2TRACK2 and IN2TRACK3), the ERA Technical Note foresees developments in eleven research areas (11 Work Streams) to be addressed to close TSI open points as well as fundamentally associated research activities.
| Project | Description and relevance | Links with InBridge4EU |
|---|---|---|
|
In2Track3: Research into optimised and future railway infrastructure (H2020 S2R project). Relevance: Concepts, knowledge, results from the research, tests and simulations related to railway bridges. |
WP1 and WP2: Similar links as with In2Track2.
WP4: Some of the algorithms to estimate damping developed within In2Track3 by UPORTO will be extended in this project and applied to a wider number of tests,
WP5: This project will use part of the models and knowledge developed in In2Track3 by UPORTO/KTH to enhance the deck acceleration criterion and partial safety factor associated to it in non-ballasted track bridges. |
|
FP3 ‑ IAM4RAIL: Flagship Project 3 – Holistic and Integrated Asset Management for Europe‘s RAIL System (H2020 EU-Rail project). Relevance: contribution to provide innovative technical requirements, methods, solutions, and services – including technical requirements and standards for future developments – based on the latest cutting-edge technologies to minimise asset lifecycle costs and extend service life while meeting safety requirements and improving the reliability, availability, and capacity of the railroad system. Both infrastructure and rolling stock are addressed. |
WP1 to WP6: InBridge4EU main objective consists of developing technical recommendations for the TSI and Eurocodes related with bridge dynamics, making it a project fully aligned with the topics addressed in the current standards that deal with bridge dynamics. |
|
Bridge Dynamic – Dynamic Load Model (DZSF funded project).
Relevance: contribution to the development of new high-speed load models able to cover effects from newer trains.
|
WP1: Aspects related with new HSLM are related with the new definition of DTCs since it is also strongly dependent on a collection of existing rolling stock data.
WP2: Aspects related with the bridge data used in the EBA project are linked with those needed to be collected in InBridge4EU. |
