Problem

Talgo serviced its trains on fixed preventive schedules. It wanted to plan work from the actual condition of each train's equipment.

Approach

Talgo's TSMART platform has monitored the fleet since 2020. With Atos (Eviden), Talgo added AI models and rules, run through an MLOps setup, to track the health of main train systems and estimate equipment lifespan. The system takes more than 30,000 signals per second per train and runs automated inspections more often. It flags early failures so work can be planned before the train reaches the depot.

99%fleet availability, per AtosVendor case study[1]

Takeaway

Fleet monitoring came first, in 2020. The predictive layer was built on that stream of live data.
