But its funny because...
TOC staff, NR Control (local), Different TOC Managed station or TOC Managed/NR Operated, Service from TOC2, External Control from [rnd] place.
Consider where you used to work (I think) and the Terminal stations it worked. 'Disjointed' really does fit. Even with the joint control points, you still have people phoning in from their respective places and then the PED.. and the TS.. needing to communicate and (can't think of the NR person at that place) still needing to pass on information. Then add in the various departments this needs to filter down to. Pass Services/Ops. It's not got any better with "technology"
Seriously; if anyone could legitimately solve the communication issues on "The Railway". You would make billions and that isn't an over-exaggeration.
Probably! Partly I believe it fundamentally can never be 'solved'. Only 'improved'.
There will always be a lot of people involved in delivery railway service, privatised or nationalised the same broad positions will be around and will just be in different "departments" rather than companies. Lines will be drawn somewhere, especially on a railway that runs across the country (such as in this case). Communications are often key as you say, but are sometimes overlooked or see as "other" compared to more operational aspects.
Different parties have the "right" information until it suddenly isn't. As you know, railway disruption can be fast-moving, unexpected and can hinge on key moments of contradictory information from multiple sources until it is clear what is happening.
