RETB is operating around the clock in some of the UK’s harshest environments
The Comms Design RETB Next Generation digital in-cab signalling system delivers safe and efficient train control across major rural routes on the UK rail network.
The iconic West Highland and Far North Lines in Scotland are signalled using the RETB Next Generation digital signalling system – a flexible, cost effective in-cab signalling system based on a SIL level 4 interlocking provided by our partners Park Signalling.
The Comms Design RETB Next Generation system delivers safe and efficient train control across major rural routes on the UK rail network.
In 2013 Comms Design were selected by Network Rail to design and deliver a new RETB system for the North and West of Scotland. Additionally, as experts in RF systems, we planned the full radio network to ensure high quality radio coverage throughout the route.
RETB equipment operates reliably in the toughest conditions in the UK. The RETB base station at White Corries in Glencoe is the highest piece of infrastructure on the UK rail network.
Comms Design’s RETB system controls long routes in the far North and West of Scotland.
Comms Design planned and simulated radio site locations to optimise coverage.
RETB lowers driver & signaller workload and adds remote management and diagnostic tools.
