The reasonably modern signalling controlled from Evesham and Ascott boxes may move to Didcot signalling centre one day, and old fashioned signalling at Moreton and Norton Junction (along with Worcester) may also be replaced, and that would allow for more automatic reports but until then I can't see any improvement unless a GPS system is installed on the trains and interfaces with the GSM-R▸ radio and CIS▸ systems.
This should be available once
SETs▸ take over almost all services. The
IEP▸ spec. calls for GPS-based
SDO▸ , and the built-in infrastructure monitoring (not always on all trains) also needs it, and in one case needs differential GPS. However, it's not been put in as a train sub-system serving other needs, just implied in the various capability requirements. And of course, even if the train knows where it is, communicating that to the rest of the world has to be provided too, and that's not in the spec.
All SETs will have AVI - an RFID tag specified by
NR» . If they put in readers that gives another way to know where each train is, at least at stations. As its use for CIS not safety-critical, putting those in should cost a lot less than if it's for signalling.
