Train Backbone Nodes

The Train Backbone Nodes are the devices applied for IEC 61375 implementation. These devices implement the TTDP protocol (Train Topology Discovery Protocol) as well as the full communication profile. 

In accordance with the standard, VDS Rail has developed the Train Backbone Routers and the Train Ethernet Repeaters in order to ensure interoperability between consists. VDS’s Train Backbone Routers perform both routing and switching tasks. 

Specific hardware by-pass and active/passive technology ensure proper redundancy between the backbone and the consist network, thus securing continuous operability. 

Train Topology Discovery Protocol (TTDP) defined by the IEC standard is used to achieve Train Inauguration procedures.
