Evidently someone forgot that Motorail isn't a thing anymore.
When something like this happens, which blocks a number of lines and could cause a serious accident if a train was to hit it, presumable there is a way for drivers and platform staff to communicate to the signaller 'set all signals near me to red urgently'?

Platform staff don’t have access to GSMR but most staffed stations will have an direct telephone line to the supervising signalbox / signalling centre other than that it’s using the internal railway telephone network.
Did the initial story get changed from "Cars are being diverted around the train..." to "Trains are being diverted around the car..."The BBC report has a helpful caption stating that "Cars are being diverted around the train at Stirling Station".
Yes exactly that. Took them about an hour I think.Did the initial story get changed from "Cars are being diverted around the train..." to "Trains are being diverted around the car..."![]()
Pull up to the 1 car stopping mark.I think the car driver misinterpreted the instruction "park between the lines"......
That was why I added a screenshot rather than just a link to a page that was likely to be changed later.Did the initial story get changed from "Cars are being diverted around the train..." to "Trains are being diverted around the car..."![]()
Apparently, there were two young ladies in the car. It has now been removed, but in doing this some copes on Platform 2 were damaged. The NR civils subcontractor is ready to replace these tonight.
It is rumoured that the cost of delays, etc, is up to £1m!![]()

Yes, the GSMR emergency button
Would the car's insurer / MIB actually be liable for delay minutes?
The GSMR doesn't set all signals to red (afaik) It sends an EMERGENCY STOP message to all trains within specific cells. Sadly it is possible to miss a GSMR EMERGENCY STOP message :/
If it had been an electric Nissan car, the delays really would have been because of the wrong sort of Leaf on the line.
The signalling workstation should have an SGRC (Signal Group Replacement Control) which when activated will revert all signals allocated to that particular group to danger. On the WestCAD workstation in our depot it will revert every GPL to red. There is also the ESOC (Emergency Signals On Control) or something like that, a big red button which if hit reverts all the depot signals to red but apparently it also drops everything else so any routes, reminders etc will drop out so it really is the Nuclear option, hence why it has a plastic cover over it to prevent accidental operation.

What you described only works in a modern workstation based environment and there is plenty of signalling in Great Britain that has no such capabilities especially lever frames IFS panels and most NX panels up to mid 80s vintage.
In the 1980s multi panel box I work only 2 of the 10 panels have emergency group replacements and that’s because either they are a late addition when our box expanded it’s area of control or part of a major relocking during a rebuild of one of our major stations in both these cases it’s the use of “Smartlock Computer Based Interlocking” CBI that enabled those features
The rest is the signalling Centre still uses “Route Relay Interlocking” RRI and as such we only have a signals on function for the part of the interlocking that are controlled by a “Time Division Multiplex” TDM.
All of our automatic signals and we have vast miles of them come under a “Frequency Division Multiplex” FDM system and we either have no replacements or non proved replacements at best for them.
Going back to Stirling Middle Signalbox, I know it was a level frame (96 levers apparently) for the main lines through the station and either a small NX panel or workstation for the Alloa branch and Stirling North is a level Frame (48 levers apparently) would of had no such group replacement facilities in this case, not unless their lever frames were replaced with more modern controls systems under the central belt electrification project.
I guess nothing will happen to the driver if the signal drops to red from green and they are doing linespeed just before it resulting in a spad?
As long as the driver reacts with the brakes anyway.
This is what happens when you don't have a traffic barrier between the car park and the platform. Entirely avoidable.
