Rail networks carry inherent geotechnical and structural risk, with long, often remote sections of track surrounded by earthworks, embankments, and critical infrastructure that require ongoing rail monitoring. Asset owners and engineers must manage these risks throughout the design, construction, operation, and renewal phases.

Geosense supports major rail networks worldwide with high precision sensors, loggers and wireless systems, providing geotechnical and structural insights for engineers across earthworks and embankments, critical rail infrastructure and track monitoring. Notable programmes include deployments with Network Rail in the UK and across the Australian rail network.

Instrumentation and monitoring play a vital role in rail to:

• Ensure safe operations
• Control geotechnical and structural risks
• Verify design and construction performance
• Detect movement early and confirm stability
• Meet regulatory and industry standards
• Reduce maintenance and whole‑life costs

Rail Monitoring: Earthworks & Embankments

Geosense offers a comprehensive range of subsurface and surface sensors to understand geotechnical behaviour in cuttings and embankments, monitoring ground movement, pore pressure, and deformation.

The large-scale deployment of In-place Inclinometers (IPIs) in embankments by Network Rail, the UK’s rail asset owner, has enabled automated monitoring of trackside earthworks across different parts of the network. The Australian rail network has also deployed our IPI-X, our combined Inclinometer/Extensometer system, to add settlement/heave data from the same borehole.

Early insights help engineers manage instability, prioritise maintenance, and protect routes that rely on long earthwork sections.

Rail Monitoring: Critical Rail Infrastructure

Geosense structural and Geotechnical sensors are used in rail tunnels, bridge monitoring, stations, retaining walls, culverts, and gantries. They deliver dependable data through every project stage, from construction to long‑term asset monitoring. This helps distinguish significant movement from acceptable behaviour, guiding timely intervention and minimising disruption.

Rail Monitoring: Track Monitoring

Geosense solutions used in railway track monitoring systems include Tilt Sensors measuring cant. Connection with our wireless node and gateways enables rapid data transmission, supporting fast event detection and continuous trend analysis.

Rail Monitoring: Data transmission

All Geosense sensors are designed for straightforward integration with our robust data loggers and wireless nodes, delivering decision‑ready information across track, earthworks, and critical structures over long distances, supporting safer operations and improved whole‑life asset performance.
