Critical Software Unveils Groundbreaking ETCS + STM Railway Solution for Portugal
A major step forward in national railway modernisation and European interoperability.
Developed in partnership with Hitachi Rail, the new ETCS + STM solution marks a first for Portugal and promises a safer, more efficient and future-ready rail system.
On 16 July, we proudly unveiled our pioneering ETCS + STM railway solution - the first of its kind developed in Portugal - during a public demonstration held in Poceirão, Lisbon. This achievement is the result of a close partnership with Hitachi Rail GTS Portugal and marks a major milestone in our country’s transition to the European Train Control System (ETCS).
We designed the new STM (Specific Transmission Module) specifically for Portugal’s existing railway infrastructure, allowing our national CONVEL system to operate alongside ETCS. This ensures a smooth, phased migration, helping to modernise the rail network without disruption. The system is currently undergoing lab and onboard testing, with full SIL 4 certification expected by 2026.
With an initial order of around 100 units, including for CP’s new Stadler trains and freight locomotives from Medway and Alpha Trains, the solution is already proving its value. Its flexibility and compatibility with various ETCS platforms also create new opportunities for suppliers and operators in the Portuguese market.
As our Business Development Director, Miguel Cardoso, highlighted, this solution represents our commitment to the future of the national railway by “improving operational safety, extending the lifespan of rolling stock, and enhancing the sector’s competitiveness through better European integration.”
Our partner, João Araújo, CEO of Hitachi Rail GTS Portugal, added that “this is a key step in the evolution and maturity of the Portuguese rail network, boosting both national and cross-border interoperability.”
The demonstration brought together key partners and clients, including Stadler, Medway, and Alpha Trains, who played an active role in the development and integration of the solution. Showcasing the first vehicle already operating with the system was a proud moment for all involved, and a clear signal of the impact our work can have on the future of rail transport in Portugal.
