Top tier rolling stock owner reduces train breakdowns
Amygda was engaged to use its unique data innovation and platform approach to increase train reliability, avoid customer dissatisfaction and penalty payments.
Amygda was engaged to use its unique data innovation and platform approach to predict engine shutdowns 7 days in advance.
Challenge
The rolling stock company was unable to predict engine failures in winter months.

Predicting engine failures early would allow the rolling stock owner to carry out the necessary maintenance when the train was scheduled to be in the depot and avoid the penalty payments for delay or disruption.
Solution
Through our empirical approach, we set-up a good understanding of the train data and maintenance information. Our platform is able to cope with over 600 sensor parameters acquired every few seconds. We analysed 100 billion data points.

We were able to categorise historical engine shutdown into different root causes. This enabled us to apply focused methods for different categories of engine shutdown.

We added terrain slope analysis by using GPS co-ordinates available in the orbital data and slope information via open public data. This increased the effectiveness of our methods in predicting engine failures.
Impact
Amygda was able to predict engine failures between 2 and 11 days before failure. This enabled the rolling stock owner to optimise train operations and reduce maintenance costs.

We were even able to categorise to a high level of accuracy the sub-system within the engine that was at risk of failure.
Outcome
Root cause analysis
Provided details of specific sub-system failure, enabling better maintenance
Up to 11 days early
Warning time for the rolling stock owner to schedule maintenance
Validation
We coped with high-frequency data and provided results in 6 weeks
