The 1st edition of IRS 80864, part 4, “Technical Specification – Permanent way – Supply of steel fish-plates” published in January 2023 is part of a second series of UIC Leaflet 864 revisions regarding track materials, as another set of complete standards or specifications does not yet exist. IRS 80864-4 has been developed as part of the Track Expert Group’s work to migrate UIC Leaflets 864-4, 6, 7 and 8 into IRSs.

A heartfelt thanks must be extended to all of the experts and UIC staff involved in producing this new IRS over the past few years, especially to Stefano Rossi from RFI and Bernhard Knoll from ÖBB.

Work will continue this year with the revision of UIC Leaflets 864-5, 864-6 and 864-7.
