In September 2023, 11 partners from five European countries, launched the InBridge4EU research project, funded by the European Union and Europe’s Rail, to solve several open points affecting the current Technical Specification for Interoperability for the Infrastructure subsystem (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 EN15228:2015 and the limits of validity of the static compatibility checks currently stipulated EN15228:2021, the accuracy of the current dynamic amplification factors and damping values for railway bridges proposed in EN1991 2 (2003) and the validity of the deck acceleration limits imposed by EN1990-Annex A2 (2005) in both new and existing bridges.

During the event, consortium members will provide information on the programme’s motivation, objectives and results achieved, and discuss key questions regarding the future of bridge dynamics and normative assessment.

Agenda for the event:

Day 1 – 8 July 2026 (morning and afternoon)

• Welcome
• Presentation and discussion on the main topics
• Discussion of WP1: Definition of Dynamic Train Categories (DTCs) for ensuring compatibility of the interface between trains and bridges
• Discussion of WP2: Identification of critical bridge parameters for the assessment of the economic impact of the new DTCs
• Discussion of WP3: Revision of the dynamic factors φ′ and φ″
• Discussion of WP4: Revision of damping in railway bridges

Day 2 – 9 July 2026 (morning)

• Discussion of WP5: Revision of bridge deck acceleration limit
• Discussion of WP6: Recommendations for dynamic compatibility checks, TSIs and Eurocodes
• Closing

Interested participants are invited to join the event in person. Online participation will also be available. 

Registrations for in-person attendance are open until 30 June 2026.
