Automate your trackside maintenance

The CrocoLifeCheck is a moving laboratory which allows the automation of crocodiles’ maintenance for Infrastructure Managers, without sacrificing the quality of the assessment. Highly detailed signal quality information is produced by the CrocoLifeCheck every time it passes over a crocodile.


Crocodile presence is detected by injecting a light current between the two installed crocodile sensors.

  • Physical detection of the trackside crocodile even if no voltage is present
  • Millimetric measurement of the contact length of the brush with the crocodile
  • Measurement of the DC voltage (1% precision) between the crocodile and the rail during the contact time. This will give information about the contact quality
  • Trackside positioning of the crocodile and location conformity assessment with respect to track databases
  • [OPTION] Specific Mechanical brush crocodile height measurement with respect to top of rail

Usable on both diagnostic and commercial trains, it clearly asses crocodile quality, positions, detects and localizes faulty ones.
