UIC IRS 90930-90940 Stakeholder Workshops to be held on 5 and 6 November 2018 at Paris UIC headquarters

Share this article

On 5 and 6 November 2018, UIC will host at its headquarters in Paris two stakeholder workshops dedicated to International Railway Solutions (IRS) currently in development. The aim is to present and discuss with all stakeholders the structure and high-level content of the work that is being done. Both IRSs deal with matters related to energy consumption and energy efficiency.

5 November 2018, 11:00-17:00 – IRS 90940 (SFERA Project: Communication with Driver Advisory Systems)

The adoption of Driver Advisory Systems (DAS) throughout Europe is increasing. DAS can significantly improve the energy efficiency of traction: Connected-DAS (C-DAS) in particular – i.e. DAS connected to Traffic Management Systems – can give the most benefits.

IRS 90940 aims to facilitate the use of DAS for international traffic by standardising the data exchange between on-board systems and Traffic Management Systems (TMS). The scope includes both ERTMS/ETCS Limited Supervision and Class B train protection systems. The format is also useful for Standalone DAS (S-DAS) by standardising data interfaces between Infrastructure Managers and Railway Undertakings. It will also be possible to express ATO over ERTMS messages (Subset-126) in SFERA format.

The interested stakeholders (e.g. RUs, IMs, DAS and rolling stock manufacturers) can register here:


6 November 2018, 09:00-15:00 – IRS 90930 (Traction Energy Settlement and Data Exchange)

IRS 90930 will be replacing most of UIC Leaflet 930. The work intends to outline a common European way of settling the energy use of trains and locomotives, by defining roles, processes and requirements for all parties involved (Infrastructure Managers, Railway Undertakings, etc.). It includes commercial and technical requirements, recommendations and common solutions, and specifies requirements for the exchange of data and information between the parties and their systems.
This IRS is being developed in line with the latest relevant European regulations and standards: new amendments to EU Regulations 1301/2014 and 1302/2014, TSI Rolling Stock and Energy, CENELEC standard EN 50463 “Energy Measurement on Trains”.

The interested stakeholders (e.g. RUs, IMs, energy suppliers, traction unit owners) can register here:
