EN 50155 switches are ruggedized Ethernet switches specifically designed for the demanding environment of railway rolling stock (trains). They adhere to the stringent requirements set forth in the EN 50155 European Norm, ensuring they can withstand the vibrations, shocks, and temperature extremes encountered in train operations. Core Function: EN 50155 switches act as the workhorses of a train's network. They function by: Expanding the Network: They allow multiple devices onboard the train to connect and communicate efficiently, reducing congestion on the overall network. This is crucial for connecting various systems like passenger infotainment, CCTV cameras, and control systems. Segmenting the Network: EN 50155 switches can segment the train network into smaller, more manageable sections. This improves data flow by preventing traffic overload on a single network segment.
