Commission Implementing Regulation (EU) 2026/693 introducing significant improvements to the technical specifications for railway control-command and signalling equipment (CCS) was published in the Official Journal of the European Union on 15 April 2026. The new framework focuses on strengthening the interoperability of the rail system and on the wider deployment of innovative technologies, such as automated train driving, across Europe.
Key innovations of the Regulation:
1. Automated management integration
The Regulation establishes new testing procedures for Automated train driving (ATO) equipment based on the latest “baseline 1” specification. . This will pave the way for a higher level of automation on the trans-European rail network.
2. Development of the ETCS system
New test specifications are being introduced for “baseline 4” of the European Control-Command system (ETCS), ensuring a higher level of safety and performance.
3. Simplified system versions
In order to optimise costs and facilitate implementation, the Regulation describes in detail reduced versions of the system (2.1 and 2.2), allowing for a more flexible adaptation to the needs of different railway lines.
4. Improved transitional arrangements
The Regulation clarifies transitional measures for existing projects and contracts in order to avoid excessive costs for industry and ensure a smooth transition to the new standards.
5. Interoperability of radio communications
This Regulation is complemented by the obligations of infrastructure managers to ensure the continued interoperability of radio communication systems, which are critical for the safe movement of trains across borders.
These changes are an important step towards a Single European Railway area, making rail transport more competitive, environmentally friendly and technologically advanced.
