Signalling & Train Control Systems
Lineside Equipment
Standalone signaling devices designed to meet specific railway safety requirements effectively.
Level Crossing Obstacle Detection
The Level Crossing Obstacle Detection System (LOD) automatically detects obstacles at level crossings, preventing accidents. It uses laser infrared technology based on the time-of-flight principle to scan the area after barriers close. The system alerts when obstacles are detected, allowing safe train passage only when the crossing is clear. LOD integrates with traditional protection systems and communicates with Interlocking Systems. Its SIL-4 architecture ensures high reliability, even in harsh weather. It offers easy installation, minimal sensing units, and seamless integration with existing systems.

Eurobalise
Eurobalise stores infrastructure data (e.g., position, speed limits, line gradient) as pre-formatted “telegrams” and transmits them to trains when energized by the train’s antenna. It complies with UNISIG “SUBSET-036” and “SUBSET-085” standards, ensuring interoperability with ERTMS and SCMT systems. Eurobalises work with ATP systems like KVB, EBICAD, and RSDD. Fixed balises store line data telegrams, while switchable balises transmit data based on signal aspects. They are connected to Lineside Equipment Units (LEUs) for power and data.

LED Signals
LED rail signals are replacing incandescent units, offering improved reliability, energy savings, and reduced maintenance. LED technology provides higher brightness, efficiency, and reliability, making it ideal for railway signaling. Its high switching speed and compatibility with silicon chip manufacturing enable versatile applications. Multiaspect LED Optical Signals offer greater luminous efficiency, reliability, and lower costs, with a Mean Time Between Failures (MTBF) of 250,000 hours and SIL-4 compliance, ensuring maximum safety for railway systems.

Automatic Reclosing Relay (DRA)
The automatic reclosing relay is designed to initiate multiple reclosures of a circuit breaker after it trips due to protective relays or residual current devices (RCD). It uses a heavy-duty stepping switch and a solid-state electronic timing circuit to operate. The system automatically attempts to restore service by switching the protective relay on up to three times within five minutes, addressing temporary electrical issues like overcurrents. It requires no human intervention for activation and can be controlled remotely for monitoring and closure.
