INFILL system
The INFILL system transmits supplementary information to the train, enhancing running smoothness and release speed management.
It comprises a TEKFER CT420 encoder, a 178 Hz generator, a separator transformer, a mixer and an integrated diagnostic system.
Designed for real-time signal detection and management, it identifies faults or anomalies and enables prompt resolution.
Operational reliability and ease of maintenance make INFILL an advanced solution for train-to-infrastructure communication.
- Carrier frequency: 178 Hz
- Generator voltage: 150 Vac ±30%
- CT auxiliary voltage: +12 Vdc
- Components: encoder, transformer, mixer, frame, FS relay
- Diagnostics: signal and fault monitoring
- Compatibility: automatic block track circuits
RDD
The RDD system monitors any current leakage in the track circuits, signalling anomalies to the relay room to enable corrective action. It is installed near the inductive connection and powered by the same supply cable as the circuit.
Its intrinsically safe electronic architecture ensures continuous operation with no need for periodic maintenance.
By reducing the requirement for additional wiring, the RDD simplifies installation and enhances overall system reliability.

- Operating temperature: -25 °C to +70 °C
- Environment: outdoor, at >1 m from the rail
- Function: leakage monitoring and signal transmission
- Signal separation: decoder in relay room
- Maintenance: not required
