The Train Switch is a Fast Ethernet/Gigabit Ethernet Layer 2 managed switch specifically designed for network applications in rolling-stock environment. Its purpose is to enable the implementation of network topologies in a train. The Train Switch provides advanced traffic switching capabilities, including support for VLANs, (Rapid) Spanning Tree Protocol (STP/RSTP) protocols and the possibility to apply Quality of Service (QoS) policies. The bypass feature makes the device completely transparent to the network in case of power loss or failure, thus avoiding or reducing the impact of possible local drop outs or malfunction on network performance. Available in different models, the Train Switch supports up to 13 Fast Ethernet ports or up to 5 Gigabit Ethernet ports and 8 Fast Ethernet ports (2 pairs with bypass function).

Train Backbone Routers
A hierarchical structure with two levels of networks is needed to interconnect vehicles in close or open trains. Train Backbone Routers provide an Ethernet based gateway function as well as a proper redundancy between those network levels. In order to assure such "High Availability", Train Backbone Routers are designed with specific features like hardware by-pass and Active/Passive technology. Standard protocol is used for proper train inauguration procedures.
Network requirements push continuously for complex data management. Managed Train Switches specifically designed for network applications in rolling-stock environment. Their purpose is to enable the implementation of network topologies in a train considering such unique environment. Particular attention has been put in the implementation of protocols capable of drastically reducing first installations,configuration as well as maintenance phases costs. Moreover such devices allow for a complete automatic reconfiguration during train-sets auto-coupling in absence of double level architecture.
Based on latest industry processors technology, a robust construction make them suitable for installation in harsh environmental conditions. Wide range of options are part of the continuous improvement process to have a technological state of the art product.
