Resumen
The shift to more sustainable mobility systems is one of the major priorities to accomplish the
goals established by the European Green Deal to make Europe the first climate neutral continent by
2050. Railways plays a crucial role in this regard, but it is essential to enhance the current
resilience and capacity of the network, in particular from lifeline structures, such as bridges.
Within this regard, several open points affecting the current INF TSI and described in the ERA
Technical Note are yet to be closed, namely those related to the Dynamic Train Categories
previously specified in ENl5228:20l5 and the limits of validity of the static compatibility checks
currently stipulated ENl5228:202l, the accuracy of the current dynamic amplification factors and
damping values for railway bridges proposed in ENl99l 2 (2003) and the validity of the deck
acceleration limits imposed by ENl990-Annex A2 (2005) in both new and existing bridges. InBridge4EU
aims to answer these points through the formulation of an enhanced and harmonized method to assess
the European dynamic interface between railway bridges and rolling stock. The outcomes of this
project will provide solid background to the guidance being drafted within the CEN/TC250/SCl
special group DIBRST for dynamics of bridges. Finally, as a consequence, the economic outcomes of
changing any of the aforementioned criteria/parameters/methodologies in the current European
railway bridge landscape will be carefully assessed. All the research carried out in InBridge4EU
will converge on recommendations to ERA and CEN for revising and updating the current version of
the TSIs and Eurocodes. Advanced numerical modelling and dynamic analyses of both bridge and
ive databases of bridge and rolling stock data obtained from the different
artners of the consortium, will contribute to the successful achievement of the project's
objectives.
