Sensonic

What Sensonic does

Sensonic is an Austria-based railway technology vendor that applies Distributed Acoustic Sensing (DAS) to existing fiber optic cables along rail corridors, turning them into continuous arrays of vibration sensors. Each 19-inch rackmount sensing unit monitors up to approximately 80 km of rail route (100 km of fiber) with a spatial resolution of 6.4 m and +/-10 m event location accuracy, using eye-safe Class 1 laser pulses at 1550 nm. On-device edge AI classifies vibration signatures into events such as train passages, trespass, digging, cable theft, vehicle intrusion, electrical flashovers, rockfalls, landslides, treefalls, washouts, and animal crossings; a cloud-connected SonicTwin digital twin and Sonic Track Index (STI) heatmaps support predictive track-condition monitoring.

The company sells a combination of hardware (sensing units with redundant power supplies and passive cooling) and recurring software/services (algorithm updates, web dashboards, periodic STI reports) to national railways, regional rail networks, transit authorities, and rail security operations. Quote-based enterprise pricing is structured around route length, number of applications, and integration scope. Sensonic operates from seven offices across Austria, UK, USA, UAE, Brazil, France, and India, with a 100+ person team that includes domain scientists, software engineers, and AI professionals. The platform holds ISO 27001 certification and CIS Benchmark compliance, and supports integration with CCTV systems, drone dispatch (via Skylark Drones), and customer operations systems via API for dashboard, email, and SMS alerting.

Named commercial deployments include a 50 km Track Condition Monitoring engagement with ADIF in Spain, a 13 km elephant detection installation on Indian Railways' East Coast Railway in Odisha, and an intrusion and falling object monitoring pilot with Chicago Transit Authority. Sensonic was founded in 2019 as a joint venture with DAS hardware specialist Sintela and remains privately held with no public listing or publicly disclosed funding rounds.

Core offering

Sensonic provides a Distributed Acoustic Sensing (DAS) platform that turns existing single-mode fiber optic cables along railway corridors into arrays of vibration sensors, then applies AI and machine learning to detect, classify, and locate events for railway operators. A single sensing unit monitors up to 100 km of fiber (~80 km of rail route) and concurrently runs multiple applications including Track Condition Monitoring, Physical Security Surveillance, Natural Hazard Monitoring, and Catenary Flashover Location.

Product overview

Sensonic offers a unified railway monitoring platform based on Distributed Acoustic Sensing (DAS) technology that transforms standard fiber optic cables into arrays of vibration sensors. The core technology platform creates a SonicTwin digital twin of entire rail routes, supporting multiple simultaneous applications from a single sensing unit. The product portfolio includes four main application modules: Track Condition Monitoring (TCM) for infrastructure health analysis, Physical Security Surveillance for trespass/cable theft detection, Natural Hazard Monitoring for landslide/rockfall/treefall/washout detection, and Catenary Flashover Location for electrical fault pinpointing. Additional specialized applications include Elephant Detection for Indian Railways. The system can run all applications concurrently on a single edge device with on-device AI processing, enabling real-time detection without cloud dependency.

• SonicTwin: Digital twin visualization of vibrations along fiber optic cables enabling infrastructure monitoring across rail routes.

Products and services

• Sensonic Sensing Unit (Edge Device) Hardware interrogator unit that connects to existing fiber optic cables and acts as the central sensing device, converting fiber into distributed vibration sensors with edge AI processing for railway infrastructure operators.
• SonicTwin Digital twin visualization platform that captures all vibrations along monitored fiber optic routes, enabling railways to monitor track health, detect events, and make better infrastructure decisions by comparing current vibration signatures against historical baselines.
• Track Condition Monitoring Monitors changes in track health by analyzing vibration signatures from train-wheel rail interactions using the Sonic Track Index (STI) heatmap to identify specific locations where vibration changes indicate track defects requiring maintenance.
• Physical Security Surveillance Detects and locates security threats along railway tracks including trespassing, digging activities, cable tampering, vehicle intrusion, and animal intrusion, providing real-time alerts with precise location information for security response teams.
• Natural Hazard Monitoring Real-time detection and location of natural hazards including landslides, rockfalls, treefalls, and washouts, monitoring characteristic ground vibrations and delivering near-instantaneous alerts to enable rapid response before hazards cause accidents.
• Catenary Flashover Location Pinpoints the exact location of electrical flashover events on overhead catenary systems to within +/-10m accuracy, enabling accelerated inspections and repairs and faster recovery of operational status after electrical incidents.
• Treefall Detection Detects falling trees and large objects that strike the railway track or overhead line equipment, providing real-time alerts with GPS location to enable rapid response and reduce track clearance and route proving requirements.
• Washout Detection Detects the sudden shifting of supporting ballast as water compromises track structure, triggering alerts for speed limits, track inspections, or drone assessments to protect passengers from harm.
• Elephant Detection System Specialized detection system for Indian Railways identifying elephant crossings at elephant corridor locations to protect both endangered elephants and train operations by enabling local staff to take appropriate actions.
• CCTV Integration with DAS Security Integration enabling Sensonic's DAS detection to activate nearby CCTV cameras and capture visual identification of detected trespassers, providing both detection and identification capabilities for rail security operations.
