Products & Services
Successful rail operation requires a balanced approach that prioritizes continuous innovation, sustainable investments, energy efficiency, optimal capacity and traffic management, and enhanced safety measures. Continuous railway monitoring solutions like fiber optic sensing, which require no trackside equipment, provide significant advantages over traditional typically point systems dependent on additional infrastructure. This opens new possibilities for addressing the key success factors of modern railway operations.
Real-time monitoring of trains and track conditions enables the early detection of issues such as equipment failures or unauthorized access, allowing for rapid response and preventing costly disruptions.
By integrating fiber optic sensing technology, railway operators can optimize maintenance schedules, improve energy efficiency, and increase the capacity of existing rail infrastructure. As rail networks expand and digitalization continues, comprehensive monitoring solutions are essential for ensuring the safe, reliable, and efficient operation of railway systems worldwide.
Monitoring Capabilities:
Track condition monitoring
Rail-Wheel Contact Zone Defects
Third-Party Intrusion (TPI) & Cable Theft Prevention
Catenary flashover localization
Fire detection
Rolling stock (supports supervision, predictive maintenance and efficient operation)
Distributed Acoustic Sensing
Our DAS system continuously detects real-time acoustic signals along tracks, providing precise information on train location, speed, and potential hazards such as intrusions or equipment failures. Powered by our 2P Squared technology—which processes both phase and power measurements—our system delivers highly accurate and stable signal detection over long distances, ensuring reliable performance even in challenging environments.
Distributed Temperature Sensing
Our DTS system continuously monitors temperature, enabling early detection of heat or fire within tunnels, cable ducts and other infrastructure.
Distributed Temperature & Strain Sensing
AP Sensing’s Distributed Temperature and Strain Sensing (DTSS) technology provides critical insights into the structural health of railway infrastructure, including bridges, tunnels, and tracks. Using Brillouin-based Optical Time Domain Reflectometry (OTDR), DTSS continuously monitors temperature and strain changes along fiber optic cables, precisely detecting anomalies such as mechanical stress, structural shifts, and thermal variations.
Ideal for railway monitoring, DTSS enables early detection of risks like landslides, track deformations, and tunnel instability, enhancing safety and minimizing disruptions. Immune to electromagnetic interference and requiring minimal maintenance, DTSS offers a cost-effective, reliable solution for proactive railway infrastructure management.
