Rail Defects analysis

Train tracks have a bad habit of warping with temperature changes. The ground also dries and shrinks, causing uneven surfaces. Summer is a real problem for the train tracks, just like in strong winter, when the rails get shorter and cool. All these things cause delays.


Adaptable to any project dimension

The solution adapts to the existing assets. We can monitor the track with on board devices or on track.


Simple and fast installation

Installation satisfies all railway certifications. The system is modular, compact, hot swappable and calibration is done remotely. 


A single platform for the whole network

Reduce time spent on infrastructure maintenance.


Achieve higher level of reliability

There is an important difference between knowing nothing about your infrastructure and having a constant control.

Why Track defects analysis?

The tool set allows the track maintainer to visualize the lane status and to assess qualitatively and quantitatively the degree of defects that each section of track presents.

The objective of this functionality is to offer the maintainer the possibility of performing a maintenance based on the real condition of the lane, defining operating limits, alarms, planning times, etc.

Track Maintennace


  • Data visualization
    See at a glance the density of defects. Data allows to study the behaviour of tracks and quickly resolve failures.
  • Analytic tools
    Analysing the maximums of the daily vibration mean. Highest values are stored as a daily point for a segment of 10 meters helping to predict when vibration are uncontrolled due to high density of defects.
  • Quality parameters
    Four quality factors are available, one for maximum values, one for the density of defects per meter, and two others, one for each predicted threshold overcoming time of each of the above.

Give answers to the uncertainty generated by the most problematic rail sections on tracks

As a complementary solution we offer Blacknest SURFACE, a sensor adapted to the train's circulation needs and which requires very occasional maintenance, making its installation technically and economically feasible.

The compact IoT sensor was created with the aim of continuously monitoring the temperature of the rail, as well as the tilting and vibrations, with a device that can be easily installed. The data collected and the AI analysis are helping to prevent railtrack breaks. It is installed directly on the rail with magnets. Integrated LTE-M1 communication guarantees low data consumption and does not require repeaters to be placed on the track. 

Blacknest SURFACE is particularly appropriate for sensitive areas, such as sidings, problematic joints, or areas with significant temperature gradients.
