Siemens has designed and developed the GSM-R cab mobile for the entire GB fleet. It is a communication device for voice and data between the train and signalling centre. Communication is across the dedicated GSM network for railway.
Siemens supplies the SVR-401 to the GB market with a 4-line textual driver control panel.
In addition to the GSM-R cab mobile Siemens is able to provide fixed and radio dispatcher systems, train the trainer training for both user and maintenance requirements, lifetime product support, project management, design and consultancy services.
