Share this article

The TEG is a permanent activity group within the Railway System Forum (RSF) that works on subjects such as track layout, track superstructure design, maintenance strategies/processes, track components and the general evolution of track-related technology. The TEG is currently chaired by Bernhard Knoll (ÖBB) and its secretary is Kurt Demeersseman (Infrabel).

The meeting took place on 20 February with 24 participants in attendance physically at the Paris head office and two further participants online via MS Teams.

The session was opened by the TEG Chair who welcomed the participants.

Subsequently, Franco Iacobini, UIC Chair of the Infrastructure Subsystem Sector, put forward some reflections about the work carried out and the vision for the subsector, together with the PoSE group.

The work is continuing with the following points:

2. Review of existing IRS every 5 years (decision on the strategy for reviewing IRS 70712 and IRS 70713-1)

3. Exchange of experience on topics, including:

  • Life cycle and quality index of switches and crossings
  • Incident and accident investigation procedures
  • Ballast queries

4. Switch and crossing maintenance (discussion of the possible publication of “The inspection of S&C – State of the art report” carried out in 2011 by UIC working group “Switch & Crossing Maintenance”)

Documents published since last meeting:

During the afternoon of 21 February, after the Fibre Optics Sensing seminar, UIC activity groups TEG and PoSE held a joint meeting

Each year it is customary for a joint meeting to be organised during the same week as the winter meetings of both groups in Paris. This provides a great opportunity to discuss matters affecting both groups, and infrastructure in general.

Welcome from Franco Iacobini, Infrastructure Chair from RFI

The main topics of the meeting were:

1. General: News from UIC and the UIC Infrastructure migration plan

2. New opt-in proposals and working groups

  • Opt-in “Bridge-track interaction area, new view of Rail Expansion Devices”;
  • Opt-in “Reusing and/or recycling infrastructure components”;
  • Working group proposal “Geotechnical works impacting existing railway infrastructure”.

3. Ongoing projects – Project status:

  • Mitig4derail

4. Miscellaneous

  • Fibre Optics Sensing seminar: conclusions and next steps
  • General discussion of experts’ participation in UIC projects
