Rhaetische Bahn (RhB) in Switzerland runs a network encompassing eight lines on 382 kilometres, 58 kilometres of which is in tunnels. The Bernina line and the Albula line are UNESCO World Heritage Sites.
Rhaetische Bahn wanted to introduce a system enabling a dispatcher to handle the entire voice communication via a touchscreen operator unit. This needed to manage conversations with train drivers on the numerous routes via radio, and the calls to operating staff over the phone.
It also needed to connect radio subscribers with telephone subscribers.
The success of the system depended on developing in interface for the technical link to the digital radio system of RhB.
