Railway condition monitoring is essential for ensuring the reliability and safety of rail networks and infrastructure. Consistent monitoring of railroad bridges, tunnels, track condition and infrastructure elements helps identify system defects early, preventing costly disruptions and accidents. Railway monitoring systems provide real-time data of the track condition and other assets, enabling engineers to make timely repairs and perform proactive maintenance. This helps extend the lifespan of railway assets, enhance passenger safety and comfort, and reduce operational costs.

At Resensys, we provide a comprehensive range of wireless railway monitoring systems designed to help maintenance and repair professionals monitor cracks, deflection, and vibrations on railroad bridges, tracks, and tunnels, ensuring the integrity of the railway infrastructure. The system is capable of sending instant alerts notifications via email or text message when structural parameters exceed a user-configurable threshold of concern. 

Contact our team of experts to discuss your railway monitoring equipment needs. We can help you design customized railway monitoring systems that help build a sustainable and efficient transportation system and optimize the value of existing infrastructure components.  

Railway Condition Monitoring Systems Offered by Resensys

Our railway track monitoring systems help identify issues that may affect the performance and safety of the railway tracks.
·  Wireless Strain Gauge SenSpot™ : Stress and strain monitoring are essential for structural monitoring of railway infrastructure. Our wireless strain gauge SenSpot™ sensor can be used for long-term and continuous monitoring of strain(stress) in rails, bridges, and sleepers.
‍·  Crack and Deflection Monitoring with SenSpot^TM : Our wireless displacement meter enables real-time crack and deflection monitoring of cracks within the rails, which are not visible easily. They are used for measuring crack widths, displacement, or deformation.
·  Vibration Monitoring with SenSpot^TM Accelerometer: This wireless railway track monitoring systemcan be mounted on trains. They can capture vibrations and track irregularities,such as bridge load bearing elements, piers, loose fastenings, rail wear, etc.
‍· Wireless Humidity and Temperature SenSpot™ Sensor: This structural health monitoring systemeffectively tracks environmental conditions like thermal movement of expansionjoints affecting railway infrastructure.
‍·  SenSpot™ Wireless Water Level Meter: This wireless water level system utilizes the round-trip travel time of an ultrasonic beam to measure variations of water levels in subsurface levels, which may cause subsidence. This subsidence may affect track geometry, causing hazards on the line. Additionally, the sensor can monitor water-related issues impacting the stability of railroad bridges and tunnels, ensuring safety.
·  SenSpot™ High-Resolution Inclinometer: This wireless high-resolution tilt sensor has a resolution of 0.00016 degrees (0.5 arc seconds) and can be used to measure bridge stiffness, tilt on piers, deflection in mid span, slope instability, leading to rockfalls or landslides. These rockfalls and landslides may obstruct the track, bridges etc. leading to critical hazards if not addressed effectively.
‍ ·  Data Acquisition Systems: Resensys SeniMax™ is a high-performance data collector designed to communicate with SenSpot™ sensors that employ the IEEE802.15.4 protocol. The SeniMax™ can be solar-recharged or powered by mains.

Benefits of Resensys Railway Condition Monitoring Systems

Resensys railway condition monitoring systems provide accurate and real-time data, enabling predictive maintenance, ensuring the safe operation of railway networks, and minimizing the risk of accidents. The following benefits of these systems help them stand out.
·  Wireless and Battery Operated: All our railway condition monitoring systems are wireless and battery-operated lasting up to 10+ years. These systems don’t require on-field calibration or battery replacement, and are maintenance-free during their lifetime. They do not demand extensive wiring, making their installation quicker and easier.  
·  Rugged Construction: These railway condition monitoring systems feature rugged construction. They are weather-proof and corrosion-resistant and can operate in snow, ice, rain, high humidity, salty environments, and extreme weather conditions. These systems can withstand a wide range of temperatures from -40°C to +65°C or -40°F to +150°F.
·   Easy Mounting: These railway monitoring systems can be flange mounted on railway tracks or other structures, or fixed through self-adhesive, enabling easy installation.
·  Modifiable Solution: These systems can be easily integrated with third-party devices.
·  Energy Efficient:  Resensys SenSpot™ sensors are the world’s most energy-efficient and ultra-low power wireless monitoring sensors designed to monitor all important structural quantities in real-time.

Case Study

In February 2023, Resensys partnered with CAMCO in Chile to install an advanced wireless structural health monitoring system on a historic railroad bridge over the BioBio River. This project involved using Resensys wireless sensors, including strain gauges and accelerometers, to monitor the bridge's performance under daily train traffic and extreme weather conditions, ensuring the safety and longevity of the structure.
