Bit more about it for those that are interested:
CCF is an information display system which displays current train position and punctuality information on bespoke railway network maps.
CCF is now the standard train movements information display system used in all Network Rail control centres and also by several Train Operating Companies [The control centres overview the signalling centres and their main task is to allocate delay, log incidents, direct large incidents, reschedule services and so on]. At peak times over 500 users are logged in concurrently.
Key features of the development and installation project included:
• Geographical data configuration.
• Preparation of network maps for all regions.
• Preparation of data relating train position to timing points.
• Testing of maps and associated data.
• Specification, development and testing of additional system functionality.
• Display of signalling indications on maps.
•
Overdue and unscheduled train alarms.
• User and role administration facilities.
• System support.
• Provision of help desk for 3rd-line support calls.
• Upgrade of CCF maps in line with infrastructure changes and release upgrades on a quarterly schedule.
The Benefits
Key benefits of CCF include:
• Reduced operating costs brought about by the rapid visual identification of the status of trains on the network. Overdue and unscheduled train alarms draw the controller's attention to issues requiring attention.
• Improves punctuality by assisting in the prompt recovery from disruptions due to rolling stock or infrastructure failure.

That would be
on top of the supervision from the signalling centre pictured below, and data logging on the train and interlockings, station monitors, outputs to train crew supervisors offices and other managers (most mangers have CCF or similar in their offices) CCTV on train and stations, voice recording all lines and channels. Even the TOC and NR control centres are overseen by a national control centre on top of that!
