A network is only as strong as its weakest link. In railway systems, rail parts need regular maintenance and control to ensure safety for travelers and cargo. However, in large systems with multiple service providers and vehicles constantly in motion, special attention is needed. SBB, the Swiss national rail company, is looking to move beyond the state of the art to ensure real-time availability of quality traceability information for individual parts involved in their systems to deliver one of the world's most reliable rail journeys.
