Ethernet on trains
Ethernet has been proven in many industries to be a very effective technology for providing data communications backbones. Ethernet switches featuring a range of networking protocols are now being used to build these networks on trains, allowing a state of the art TCS (train control system) to manage every aspect of the train operation.
The onboard rail environment is one of the toughest imaginable for any electronic devices. An Ethernet switch which is going to be used in a network on a train has to exceed the tough EN50155 standard which covers a wide range of environmental requirements and ensures that equipment can survive the rigours of operation on a train.
