ENYSE Selects AdaCore’s Flagship Software Development Platform to Build Innovative Railway Signaling Systems

AdaCore, a trusted provider of software development and verification tools, today announces that ENYSE, part of the ACS group, has selected its GNAT Pro development environment to develop its new safety-critical railway signaling solutions

As part of one of its research and development department projects, ENYSE will use the tool, and the Ada programming language, to build the Radio Block Centre (RBC), a microprocessor-based system that will be the cornerstone of its advanced new rail signaling system.

Following a successful evaluation of GNAT Pro, ENYSE chose to work with AdaCore due to its certification under the CENELEC EN 50128:2011 railway software safety standard, ability to develop in both the Ada and C programming languages, previous experience and access to a full suite of solutions, including static and dynamic analysis tools.

A completely new solution, ENYSE’s RBC generates and transmits signals to trains, providing them with permission to move through particular sections of track. It needs to meet the highest Safety Integrity Level (SIL 4), under EN 50128:2011, as well as the functional requirements of the European Railway Traffic Management System (ERTMS), the pan-European train control and command system. ENYSE is now developing a proof-of-concept demonstrator of its RBC.

“Our new rail signaling project is being created from the ground up, giving us the chance to focus on innovation while still meeting the highest levels of safety,” said Francisco Lozano, Head of R&D at ENYSE. “AdaCore’s tools are the perfect fit for the project – they are designed to support safety-critical certification, while giving us the ability to develop leading-edge solutions to meet changing market needs.”

Demonstrating the scope of the four-year project, it will be delivered by a 70 strong department within ENYSE’s research and development facility in Spain. GNAT Pro will initially be used by 10 team members, covering a wide range of software development activities, from defining requirements to coding.

“ENYSE’s new rail signaling project highlights the changing requirements of mission-critical software today,” said Jamie Ayre, Commercial Director at AdaCore. “Not only do these systems have to meet safety-critical standards and ensure reliability over the long-term but they must also deliver state-of-the-art functionality. We look forward to working closely with the expanding ENYSE team to help them develop this exciting project.”

About ENYSE

Enyse is a Signalling company belonging to the Industrial Services division of the ACS group.

For Enyse, the success of their projects is based on a high level of adaptation to functional and operational needs of the various railways - flexibility is the key word. In an industry increasingly integrating technology standards, the required Reliability, Availability, Maintainability and Safety standards not only apply to system design level, but are the actual premises to properly implementing and commissioning turn-key Signalling projects.

Enyse has the ability to work in all phases of a project, from conception and design to manufacturing and maintenance of Safety installations, both for proprietary and subcontracted technologies.

ACS Industrial Services is making a determined push in the railway sector, where Spain is an active international player. To this effect, it has taken Enyse under its direct realm, making strong investments in both human resources and technical developments. Within this context, Enyse has moved its headquarters and factory to a new venue in Alcobendas, Madrid.

Enyse's human capital, track record and relationship with the ACS railway companies make it capable of offering a wide range of systems and services including Signalling but also power, telecoms or the maintenance of all electromechanical systems along any type of railway line - conventional, freight, high speed, etc.
