ETCS Level STM

Trains equipped with ETCS can run on lines where the class B system needs to be operated. ETCS acts as an interface between the driver and the national ATP.

ERTMS/ETCS trains with the national system’s Specific Transmission Module (STM) installed on-board can travel along the lines that are equipped with this system. STM equipment can provide ERTMS/ETCS with standard information taken from the information in the ground-based national systems and make it possible for the national system’s services to be used. MERMEC ETCS OBU can interface an external STM via the STM FFFIS standard bus or via custom interfaces. STM functions can be integrated in the OBU as well (bi-standard solution).

"GUARDIA" Onboard Subsystem by ANGELSTAR and Radio Block Centre

The on-board subsystem receives and analyzes the information about the trackside status and characteristics of the movement permission sent by the Eurobalise. It automatically applies brakes if the comparison of the actual speed with the permitted speed shows that restriction of the speed must be observed.

BTM Antenna Energizes the balise Acquires the telegrams transmitted from balise and Euroloop Auto-diagnostic Functioning temperature: -40°C to 70°C

European Vital Computer (EVC) Realizes odometer functionality Executes the software application Collects all the diagnostic information Auto-diagnostic Functioning temperature: -25°C to 70°C

Driver Machine Interface (DMI) Interfaces with the engine-driver Auto-diagnostic Functioning temperature: -25°C to 70°C

Radio Block Centre The platform is based on a 2oo2HR architecture and is implemented with two independent and galvanically isolated processing sections Each section is in turn made up of a pair of processors in 2oo2 architecture The interface with other ground subsystems (IXL, RBC, Supervision Systems) is provided by two Ethernet interface cards The interface with the GSM-R radio system is provided by special ISDN interface cards and Euroradio protocol.

Wayside Subsystem

The wayside subsystem is based on intermittent track-to-train communication using LEU (Lineside Equipment Unit) and Eurobalise. It can, optionally, be integrated with advanced data infill for performance enhancement.

Interlocking LEU Digitally acquires the interlocking status Serial Communication via Euroradio+ Associates each status with a 1023 bit coded telegram Transmits the telegrams to controlled Eurobalises Monitors the Wayside Subsystem's functions and memorizes both sent telegrams and anomalies found Communicates diagnostic messages to the diagnostics center in the station Auto-diagnostic

Signal LEU Acquires, through direct interface, the signal status by measuring the electrical currents transferred from the interlocking to the lights Associates each status with a coded telegram Transmits the telegrams to controlled Eurobalises or to the microwave transponder Communicates diagnostic messages to the diagnostics center in the station, by means of the same cable connected to the existing light signal Auto-diagnostic

Eurobalise When energized by RSDD Antenna, sends a telegram to trains in transit Class A Auto-diagnostic Functioning temperature: -40°C to 85°C Read more about Eurobalise
