The TSI revision package 2023, adopted by the Railway Interoperability and Safety Committee on 30 March 2023, has been published and has come into effect on 28 September 2023. 

As this package introduces significant changes that will impact all future subsystems, as well as subsystems currently subject to ongoing projects, the Agency organised a series of webinars and Q&A sessions throughout the year 2023 to give you the opportunity to ask as many questions as possible.

All the recordings of these events, as well as the slides used to respond to your questions, are accessible from that page.
