If you are reading this while sitting on a train, struggling for sufficient WiFi or mobile phone signal, bear with us. Of course, that still leaves most of the rail network without a plan. The railway’s current fibre optic cable system uses 24 and 48-count cable, according to Network Rail. This will also enable Network Rail to monitor assets more effectively, including connecting trackside sensors and CCTV applications. The entire rail network has long operated its own masts, used for communicating with drivers.
