Silicon Valley for rail

Keen to bring key innovations on the market and to keep a pioneering spirit, The Signalling Company has decided to run 24/7, 365 days per year test campaigns on its ETCS Onboard software, in compliance with official ERTMS Interoperability test sequences.

This model is a well-known Silicon Valley best practice in the software industry called Continuous Integration. Continuous integration allows the ETCS Onboard software to be continuously tested, to detect interoperability issues earlier, and to fasten the Baseline upgrade process. In traditional settings, ETCS test campaigns take months and involve a large team of engineers.

To guarantee the success and quality of these test campaigns, The Signalling Company decided to partner up with the key player Try and Cert. This association between Laboratoire ERTMS France (LEF), CERTIFER and Belgorail is the first ERTMS Accredited Laboratory to propose a technical infrastructure enabling Continuous Integration and ‘software in the loop’ testing according to official ERTMS Interoperability test sequences specified in the Subset-076 standard.

‘Software in the loop’ testing avoids the need to send ETCS onboard hardware to the laboratory, and instead uses a cloud to test the ETCS Onboard software.

Seismic shift in business model

Among other things, TheSignallingCompany proposes a new business model for ETCS Onboard including a fixed-price insurance against all future ERTMS Baseline changes to its customers. This represents a seismic shift for European Railway Undertakings: as their ERTMS investments will no longer be open-ended, RUs will actually know before they make the investment how much it will cost to keep system up to date and functioning in the decades to come. In the current business models operated by incumbents, RU’s sign a blank check.

The key technology behind such a radical business model change is the ERTMSFormalSpecs (EFS) modelling language, a Domain Specific Language that allows the production of an immediately executable model of the ERTMS specifications, without any intermediary code generation, manual or automated. ERTMS Solutions, one of the shareholders of TheSignallingCompany, has developed a Subset-026 compliant EFS model and a Subset-076 automated test suite.


The Continuous Integration will start with ETCS Onboard software in the loop continuous testing from 2020 to 2022, followed by Certification tests using TheSignallingCompany ETCS Onboard hardware from 2022 to 2023.

The ‘software in the loop test’ campaign started this summer, follow our progress on LinkedIN.
