Demo Project


Broadband to passengers, Signalling

The objective of the proposed activity is to develop a demonstration of a hybrid satellite communications and terrestrial network for use on trains.

This Satellites for Digitalisation of Railways (SODOR) project will deliver pilot demonstrations of improved network connectivity for train monitoring and passenger broadband. The project aims to demonstrate how new constellations of communication satellites can seamlessly fill gaps in terrestrial coverage and provide additional capacity to improve safety and provide travellers with better connectivity.

CGI will work with IT partners Icomera, Isotropic and 5G3i, alongside Network Rail, and rail operators ScotRail, Northern and LNER, to explore how hybrid networks, based on multi-bearer 5G technology, can improve network availability while offering better value for money than existing solutions.
