Private finance to fund Network Rail telecoms upgrade
British infrastructure manager Network Rail (NR) has entered exclusive discussions with a private-sector consortium to upgrade its telecoms infrastructure.
NR’s 16,000km of lineside fibre optic cableWould it really be that difficult considering the electricity and fibre is already there?
it's trains only I believe. Never seen one marked on cellmapper and also never been able to see one on a network scan weirdlyOn those really old looking masts by the railway, just like the one in the articles picture, what's the agreement like? All 4 ops + trains? or only some ops?

All across Europe, GSM-R radio interference shows itself in different ways, but, in Great Britain, three fault conditions have been noticed:
The cab radio goes into search mode, causing a lock up and requiring a re-initiation process that takes several minutes during which time the train cannot make or receive emergency calls;
The radio re-boots itself, which is an eight-step start up process that often only gets to step three;
The cab radio screen goes blank, which again necessitates a re-initiation.
If these occurrences were very infrequent, it might be a reasonable risk assessment to live with the problem. However, incidents now number 240 a year, often necessitating stopping the train whilst the re-boot or re-initialisation takes place, causing two to three minutes delay. In total, this results in around 8,000 delay minutes being attributed to GSM-R interference problems.
