Communication Technology for rail vehicles

Communication is what counts

Just a few years ago, Ethernet technology was used in rail vehicles almost exclusively for passenger comfort functions, such as multimedia application. In modern vehicles, the technology has now also become standard in the part relevant to train control - the Train Control & Management System (TCMS). Against this background, train bus couplers, switches and converters play indispensable roles, because communication is what counts.

Train Bus Couplers, Gateways, Switches, Ethernet Repeater and Converters

Selectron offers two product groups from the train bus coupler product family (Train Backbone Nodes): The Train Backbone Switch acts as a connection to the Ethernet Train Backbone as a train-wide interface. With a switch and router in one device, it establishes the connection to the train set (Consist) bus. In doing so, it creates the prerequisite for dynamic train inauguration and the transparent connection of other vehicle segments. Protocol-specific gateways handle the connection to the wire train bus as the train-wide interface.

Switches, such as the Ethernet Consist Switch, can be used within all components in the train set and integrate cybersecurity and managed switch functionalities. Communication converters cover all communication interfaces in the train set; for example, from the old RS-485 interface to CAN or Ethernet.
