Industry Background
Dedicated wireless communication systems serve as indispensable tools for railway signaling, track maintenance, power supply, passenger transport, and station operations. Reliable and real-time wireless communication is crucial for ensuring operational safety and secure train movements. Runbo understands the unique challenges faced by different railway departments and has developed tailored communication solutions for various scenarios, enhancing operational efficiency, safety compliance, and standardized workflows.

Railway Infrastructure Protection & Train Warning Solution

To ensure the punctuality and safety of freight and passenger trains, our track, signaling, and power supply teams must maintain the integrity of rails, switches, signals, and crossings. A robust and responsive wireless communication system is essential for daily construction and protection tasks.

Overview
Track and signaling personnel conduct year-round maintenance, inspections, and repairs along railway lines. With increasing train speeds nationwide, workers face heightened safety risks. Balancing the need for routine maintenance with personnel safety amid high-speed operations is the core challenge we address.

Current practices involve:

• Deploying station-based guards at intervals to monitor worksites.

• Establishing safety zones 800 meters ahead/behind construction areas.

• Using fixed radios to alert on-site guards of approaching trains, who then notify workers to clear the tracks.

However, field surveys reveal persistent issues:

1. Communication gaps: Long intervals between stations cause unreliable connectivity, requiring multi-level relays.

2. Signal interference: Adjacent work zones experience crosstalk during simultaneous operations.

3. Cross-zone dispatch limitations: Remote sites lack interoperable communication.

4. Weak repeater management: No fail-safe mechanisms for emergencies.

5. Tunnel dead zones: Communication range <500m inside tunnels; no tunnel-to-surface links.

6. Fragmented coordination: No unified dispatch for signaling, track, and power teams.

7. Ineffective train warnings: Unclear audio, complex operations, and delayed alerts.

Solution

Runbo’s H1 Hybrid Intercom System integrates analog, IP, and digital radios (PDT standard) with railway intranets to deliver a customized solution for track, signaling, power, and rolling stock teams. The system leverages existing infrastructure to build a future-proof digital network:

Key Features:

1. Modular IP-linked base stations: 7–10 km spacing per station, tailored to terrain and coverage needs.

2. Railway-owned infrastructure: Utilizes existing E1/G.703-compliant lines or IP links for cost efficiency.

3. Dedicated subnetworks: Isolated groups for track, signaling, power, and rolling stock teams, with cross-group dialing when needed.

4. Centralized dispatch: Remote call, recording, and monitoring via wired dispatch consoles at bureau, segment, and workshop levels.

5. Station/vehicle integration:

   • Station masters use vehicle-mounted radios.

   • Trains broadcast automated warnings (train ID, speed, location, timestamp).

6. Seamless roaming: Terminals auto-roam across the network; train radios cyclically transmit alerts received by handheld devices.

Benefits:

• Nationwide PDT digital signaling ensures interference-free, wide-area coverage.

• Digital voice recording enables accountability and incident review.

• Unified cross-department dispatch optimizes resource allocation during emergencies.

• Automated train alerts enhance worksite safety with real-time proximity warnings.

This system elevates operational coordination, accelerates emergency response, and maximizes resource efficiency across railway ecosystems.
