Awards: Works to automate the safety installations on the Ribadeo–Cudillero section. Works are being carried out to automate the safety installations along the Ribadeo–Cudillero section of the metre‑gauge Ferrol–Pravia line. The contract includes the drafting of the construction project, the execution of the works, the testing phase and the commissioning of the safety systems associated with the removal of telephone block operation along this 110‑km stretch, which runs between Ribadeo (Lugo) and Cudillero (Asturias). Award of 45 level crossings in the national network. It is also particularly noteworthy that 45 level crossings have been awarded across the national network, a milestone that not only drives the modernisation of the railway infrastructure but also highlights the technological capabilities and customer‑focused commitment that ENYSE brings to the sector. This award strengthens the adoption of advanced solutions that raise operational safety standards, improve mobility and enable more efficient operations at critical points of the network. Project in Chile. In Chile, ENYSE has also been awarded the renewal of the electronic interlocking system in Molina.

New Generation of Radio and Solar Based Level Crossings with New Barrier.

The new generation of ENYSE level crossings has been designed to be fully energy self‑sufficient during operation. By integrating secure radio communication protocols between the central unit, railway signals and warning points, the system significantly reduces cabling requirements and associated maintenance costs. In parallel, the incorporation of a predictive maintenance approach—featuring advanced functionalities specifically developed for barrier systems—further optimises lifecycle costs and operational reliability.

New SAE (Operations Support System) for Tramway and Light Metro Operations.

The system is designed to optimise tramway and light metro operations in real time, minimising manual intervention and improving operational efficiency. It combines high‑accuracy location technologies—based on balises and odometry, with GPS as a backup—with advanced, reliable communications between the onboard SAE and the Central SAE.

The new tramway SAE includes the following core modules:

- New generation of timetables/mesh diagrams: visual space–time representation of operations for planning and compliance monitoring.
- Regulation module to ensure compliance with the planned operation.
- Communication between drivers and the Central SAE (messaging and voice).
- Driver management (including credential management).
- Operations reports (early running / delays, driving, drivers, incidents, etc.).
- Driver HMI (next station, previous station, final destination, early running / delay, speed, etc.).
- Passenger information system on platforms.
