Hitachi Rail TAS Digital Signalling System Goes Live at Ciulnita Romania

Hitachi Rail has deployed its TAS Platform digital signalling system at Ciulnita station in Romania's Ialomița County. The new installation replaces the SELMIS platform that served the southeastern Romanian network for 20 years before retirement.

The TAS deployment represents Romania's adoption of next-generation interlocking technology as European operators modernise aging signalling infrastructure. Digital platforms like TAS offer enhanced capacity management, reduced maintenance requirements, and improved fault detection compared to legacy relay-based systems. The technology provides CFR Infrastructură with real-time operational data and remote diagnostic capabilities that were unavailable with the previous SELMIS installation.

Ciulnita station serves as a critical junction in the Muntenia region's rail network, connecting southeastern Romania's passenger and freight corridors. The TAS Platform utilises object-oriented software architecture and standardised interfaces that allow for future system expansions and integrations. Hitachi Rail's TAS technology has proven operational reliability across European networks, with installations spanning multiple countries and operating conditions.

The Ciulnita deployment forms part of Romania's broader railway modernisation programme as the country upgrades infrastructure to meet European interoperability standards. CFR Infrastructură continues investing in digital signalling technology to improve network performance and align with EU technical specifications for interoperability. Hitachi Rail's TAS Platform competes directly with Bombardier's EBI Lock and Siemens' Simis interlocking systems in the European digital signalling market.
