Case Study: Swiss Federal Railways SBB keeps trains running on time with MongoDB Atlas

Swiss Federal Railways SBB keeps trains on time with MongoDB Atlas and zero outages in year one

Swiss Federal Railways SBB needed to modernize its data infrastructure to manage its dense rail network reliably. The company’s reliance on an in-memory database for critical formation and train running data posed a growing risk of downtime, especially during software updates, which forced restrictive release cycles. To create a future-proof and persistent system, SBB sought a document database solution and partnered with MongoDB, selecting its MongoDB Atlas platform.

By migrating microservices to MongoDB Atlas clusters, SBB achieved a stable, developer-friendly environment with zero downtime during updates and automated backups. The solution gave developers confidence to release features more often, reported no outages in the first year, and improved operational agility. As a result of this successful implementation, other teams within SBB are now evaluating MongoDB for additional critical applications, such as the ticket purchasing system.
