With VABnet obu, Verkehrsautomatisierung Berlin provides a flexible on-board computer for public transport.

Thanks to its high level of modularity and configurability, the system can be deployed in trams, buses and trains. The touch control terminals are designed for 100% integration into the cab control panels of the respective vehicles.


Depending on configuration and application, operation is via 10“ touch control terminals on the driver’s workstation (tram and train) or a tablet PC with for example an 8“ display, which is installed on the driver’s workstation on the bus.


VABnet obu has all the necessary interfaces. VABnet obu connects to the periphery – via IBIS, Ethernet, serial, digital or USB. Wi-Fi and LTE are available for communication. The H&K communication system HCS can be connected by the VABnet obu via the touch control terminal and via an RS485 interface. In this case, commands for point setting can be entered via the touch monitor. Data is communicated to other on-board unit systems and to the passenger information devices in the vehicle via the Ethernet interfaces.
