Hopefully the recently installed signals between Droitwich and Worcester will help with some of the woes.
I am assuming that all stations on the Cotswold Line will have real time information after the redoubling (and that the National Rail tracker dep boards will work).
It'll still be Absolute Block signalling so that won't change things. We will have to see what type of system is installed when the current
CIS▸ gets replaced - GPS would appear to be a logical step forward, but that would mean the train also having some kind of identification system fitted.
