Duration in months: 18

Problem Description

Alstom is investing huge effort in creating new services for the railway industry and other transportation fields. One of the main areas of investment currently is the development of a diagnostic service to automatically schedule maintenance intervals.


New services


A diagnostic service would need to: understand how parts degrade and determine which would need to be serviced at each interval# automatically plan availability of spare parts or consumables# and quickly report to engineers what needs to be done in order to service the train and the network, as efficiently as possible.

Innovation results

The experiment aimed to predict the effects of failures in railway infrastructure components, using HPC. It studied dynamic interactions, dynamic load, and failure modes of turnout, focusing on high-speed train transit and turnout failure modes.

Business impact

Alstom and Hypertec have reported significant benefits from replacing field measurements with simulation-based diagnostic, resulting in a 50% decrease in time-to-results and cost savings of 50k€ to 70k€ per application. This led to an 87% increase in HPC-related revenue from 45k€ to 100€ in next 4 years.
