Slide Railway monitoring FOR RAIL OPERATORS

Monitoring challenges

Long range monitoring

You need to monitor long rail tracks covering remote distances.

Track stability & geometry

It’s necessary to keep the rails in line just as they were designed and positioned on site.

Dynamic & Static monitoring

It’s necessary to monitor for a long period of time both the dynamic and static part.

Surrounding stability

Monitor slow subsidence of the ground due to work near the railway bed or to weather agents.

KEY PARAMETERS FOR RAILWAY MONITORING

Using a series of Tiltmeters or Tilt-beams, mounted on the sleepers, it is possible to obtain their rotations and longitudinal deformation, that represents the ground deformations.

The dynamic part of the monitoring is carried out with Deck sensors that allow you to monitor the dynamic displacement of the sleepers when the train passes.

With the use of Analog and Digital communication nodes, it is possible to complete the monitoring system with all non-native wireless geotechnical sensors.

Cant of the tracks

You can monitor the cant or the measurement of the difference in elevation between the outer rail and the inner rail.

Twist of the tracks

You can display the longitudinal deformation and the transversal deformation in percent between two crosspieces.

Vertical deflection

You can monitor the vertical displacement of the track and reconstruct the broken line of longitudinal deformation.

Ballast void

You can monitor the ground displacement (settlement or lateral movement) and correlates the amplitude of oscillation of the sleepers with the variation of the ballast.

Cant Tilt icon Cross level of the tracks The transversal level is defined as the transversal slope of the track expressed as the difference in height between the two rails. The use of the Tiltmeters, positioned on the sleeper, permits to get the measurement of the difference in elevation of the tracks using the tool and to monitor its trend over time. Tilt icon Tilt icon Tilt icon Twist Tilt icon The twist is the algebraic difference between two transversal levels taken separately at a predefined distance, usually expressed as a gradient. The use of the Tiltmeters, positioned on the sleeper, allows to calculate this parameter. The twist is the most delicate thing for the stability of the vehicle-track coupling, it is often the case of a train derailment. Twist of the tracks Tilt icon Tilt icon Tilt icon Deflection Tilt icon Tilt icon Longitudinal deflection Tilt icon Tilt icon Tilt-beam of different lengths (1; 2; 3m), if placed in a chain, allows to calculate of the track's vertical displacement and reconstruct its deformation with a broken line. In this way, it is possible to obtain and visualize the exact vertical lowering of the tracks. Ballast Ballast void Tilt icon Tilt icon Tilt icon Tilt icon The contamination of the ballast from external materials, known as fouling, can compromise the integrity and drainage capacity of the ballast. The Deck sensor, installed on the sleepers, allows to monitor the dynamic oscillation amplitude of the sleeper as the train passes and to correlate its variation to the degradation of the ballast.
