When we think about global transport, we tend to assume it works like a fairly predictable machine. Ships crossing oceans, well-established routes, and more or less controlled timelines. However, it only takes one key element to become unstable for the entire system to start feeling the strain. That is exactly what is happening right now…
Just over a century ago, traveling by train was a very different experience from what we know today. Steam set the pace, open windows were part of the journey, and trips were measured more in time than in efficiency. Technology was present, but in a much more visible, mechanical, and, in a way, simpler form. …
Not all systems within a train perform the same function. But many share something important: they operate under demanding conditions and cannot fail. In this context, functional safety standards such as SIL2 (Safety Integrity Level 2) have become a benchmark for designing systems capable of responding safely, even when something doesn’t go as expected. So…
