Amberg TrackControl Dynamic
Next Generation Track Monitoring
Nowadays, tracks are generally monitored in an unloaded state. However, deformations under load during the passage of trains are of interest. The new Amberg TrackControl Dynamic solution enables the dynamic measurement of all relevant track parameters under load.
We are pleased to carry out your project
In collaboration with our technology associates and in-house specialists, we provide state-of-the-art solutions and instruments tailored to your needs.
System Description
- 24/7 monitoring of track stability in loaded and unloaded conditions
All-in-One Solution - Monitoring of all relevant track parameters
Track swing, superelevation, twist, vertical versine - Scalability
From single-point measurements to entire track sections - GEOvis Cloud Software
Real-time results available around the clock
Applications
- Early detection of effects from construction sites close to the tracks (e.g. undercuts, pipe jacking)
Damage to the subgrade cannot be immediately detected in static measurements. Track subsidence when trains pass over indicates weak spots at an early stage. - Early detection of structural weak points of the rail superstructure/substructure (e.g. underwashing)
Long-term monitoring of known problem areas. - Monitoring of transition areas of auxiliary structures / auxiliary bridges
In transition areas to temporary auxiliary structures, weaknesses in terms of stability often occur. The result is slow speed zones. Permanent dynamic monitoring of all track parameters can increase safety and, if possible,
prevent slow speed zones. - Site investigation
Determining the subgrade conditions based on the depth of track subsidence during train passage, as a function of groundwater levels and weather conditions.
Comprehensive Track Monitoring
The newly developed and patented sensors can precisely determine the track sinking depths for each wheel axle as the train passes. The combined measurement of the static track position and the dynamic track deformation enables comprehensive monitoring of the tracks. The Amberg TrackControl Dynamic measuring system can be used to determine the effective track parameters ‘track superelevation’, “twist” and ‘vertical versine’ under load.
In addition to real-time measurements (maximum/median per train), the GEOvis monitoring cloud software can also be used to analyse and visualise long-term behaviour. This allows comprehensive monitoring of track position and stability and early identification of trends. This enables cost-effective and proactive planning of maintenance work on the substructure and superstructure of the track infrastructure.

Frequently Asked Questions
With Amberg TrackControl Dynamic, you can see how your track behaves when trains pass. In addition to its unloaded position, you can monitor track sinking and dynamic track parameters under operational loading. This gives you additional information about the behaviour and stability of your track.
Dynamic monitoring is particularly useful when the behaviour of your track under train loads is relevant to your project. It can help you investigate potential weak points in the track structure or subgrade, monitor construction activities and assess changes that may not be visible from static measurements alone.
You can monitor track sinking depth, dynamic track cant, dynamic twist and dynamic vertical versine. The system can also calculate effective twist and effective vertical versine by combining static and dynamic components. Train speed can also be recorded.
Dynamic sensors detect a train passage and record the movement of the track during the passage. The system determines sinking depth for individual wheel loads and calculates characteristic values such as maximum and median sinking depth for each train. The results are then transferred to GEOvis for analysis.
By monitoring how much the track sinks when trains pass, you can identify changes in the behaviour of the track and potential weak areas in the superstructure or subgrade. The measurements can also be analysed together with other conditions, such as groundwater and weather data, when investigating subgrade behaviour.
Yes. Dynamic monitoring can be used for applications such as construction work close to or beneath railway tracks, pipe jacking, tunnelling and other activities where changes in track behaviour under train load are relevant.
Yes. You can combine both measurement types to obtain a more complete picture of your track. Static measurements show the unloaded track position, while dynamic measurements show its behaviour under train load. GEOvis can display the different components separately and calculate effective track parameters from them.
Static measurements are typically available in one-minute cycles. Dynamic measurements are automatically recorded when a train passage is detected, with characteristic values calculated for each train. For specific applications, shorter measurement intervals can also be implemented.
In GEOvis, you can analyse individual train passages as well as longer-term trends. Dynamic sinking can be displayed as individual peaks or as maximum and median values over time. You can also compare static, dynamic and effective track parameters to identify changes in track behaviour.
The documented 1-sigma accuracy for track sinking is ±0.2 mm for movements up to 2 mm, ±0.25 mm for movements up to 3 mm and ±0.40 mm for movements up to 5 mm. Dynamic track cant and dynamic vertical versine are specified at ±0.5 mm.
