Lineas, the larget train freight company in Europe, has a mandatory mid-life maintenance cycle for all its locomotives. They have a total of 200 locomotives. They do not all serve the same routes or do the same functions; some are used for shunting, while others travel short routes or long ones.
Based on the data collected from over 200 sensors on each locomotive, generating billions of records, we managed to compile a model that suggest the time after which each locomotive needed to undergo its “mid-life” maintenance cycle.
When averaging the results, we managed to extend the life-cycle per locomotive by 15%. As a result, the savings generated are considerable.
