Same deal today. Large numbers of cancellations in thames valley services.
The National Rail web site over the last day or three consistently shows a good service on
GWR▸ at a time that GWR consistently states that signalling centre operations are disrupted (could it be argued that signalling centre operations being disrupted should be a 'never event', and was it the likes of Ian Prossor who, not so long ago, were twitchy about signalling centres having created a single point of failure).
GWR's tweet earlier today:

"Controlled disruption"......there's a new one for the bingo card!
