CHALLENGE

Maintenance contractor for Rail Infrastructure executes maintenance based on human inspection of rail track videos.

Introduce predictive maintenance technology to streamline and improve inspection.

APPROACH

  • Gather data on inspections executed to create a large test set of observations.
  • Develop a deep learning algorithm (based on neural networks) to automate the inspection.
  • Minimise false positives (judged okay but in fact not okay) and false negatives (judged not okay but in fact okay).
  • Test and validate the software in the live environment.
  • Transfer the software to the maintenance organisation.
