Siemens Mobility to upgrade communication radios for Network Rail

摘要

Siemens Mobility has been awarded a 36 million EUR contract by Network Rail, one of the largest rail infrastructure providers in Great Britain, to upgrade the GSM-R cab radios of the entire Great Britain rolling stock fleet. From October 2019, GSM-R software and hardware in 9052 cabs will be upgraded to the fourth generation (V4.0), offering greater immunity, better voice quality and higher performance. The upgrade is scheduled for completion in March 2022. In addition, Siemens Mobility will supply 11000 rail radios including 1948 replacement units. The program to upgrade over 11, 000 GSM-R cab mobiles to V4.0 would deliver significant benefits to passengers and the railway. It would resolve the rail safety risk and performance impact attributed to interference on the railway from public mobile network operators and would enable them to improve their coverage for passengers at locations where they had been asked to turn down their coverage or power, stated Simon Atterwell, Director, Network Rail Telecom. "The program also provides the opportunity to explore additional railway applications such as GPS location data for train positioning location and the trial of a track remote condition monitoring application. We look forward to working closely with train and freight operating companies, and Siemens Mobility, in the delivery of this nationally important program," Atter well added. Siemens Mobility has completed a series of trials with Network Rail to demonstrate and prove the GB version 4.0 software and Nexus hardware. Covering more than 100 trains, the trials were undertaken over a 2-month period and successfully concluded in January 2019. They achieved an average mean time between failure in excess of 50,000 hours.
