GSM-R’s continued success depends on all who use it
Phased into service across Britain’s rail network between 2007 and 2014, GSM-R is already a major achievement, requiring the renewal of the entire lineside network that supports the railway’s daily telecom needs.
However, there’s much more to come. Future enhancements to the system include a software upgrade supporting the roll-out of European Rail Traffic Management System (ERTMS). Delivering enhancements such as these and continuing the success relies on collaboration with everyone who uses the system.
Cab mobile V4 upgrade
This multi-million pound industry-wide programme seeks to address rail safety risks and the performance impact of interference from other mobile network operators’ services. The programme will upgrade every train driving cab’s GSM-R hardware and software to cab mobile version 4.0. This national deployment encompasses some 9,000 cabs and commences in October 2019. For more information about this programme, please email: NRTenquiries@networkrail.co.uk
GSM-R service levels can be impacted by a diverse range of factors such as, interference from the public mobile network operators, the effects of vegetation growth and new buildings built near the railway. To combat these, data from the cab radio fleet is constantly monitored and used to identify locations where the GSM-R network needs attention. The data is also used to plan changes and upgrades to the GSM-R network to address identified issues and thus, optimise the network.
Our continuous improvement worksteams, focused on the technical, behavioural, process and people aspects of the overall GSM-R service performance, aim to minimise train delay and maximise availability of the service, supporting drivers and signallers when they need it.
How you can help
If you’re working on the railway, you can help to make the GSM-R communications system better by reporting any problems or faults.
