I hope the driver is ok and makes a full recovery.
It is fortunate that he was able to get the train to a station. What would have happened if this was between stations and it was left to passengers to try to summon help? I wouldn't have a clue where to direct an ambulance to, and I wouldn't have a clue how to contact the TOC control or signaler for help.
This is a serious question: If I phoned 999 and said I was on a train somewhere between two stations, would the emergency services be able to locate the train? Would they contact Network Rail?
Fortunately these circumstances are rare but given DOO trains are common, is there any advice for passengers who have to deal with a situation where the driver is ill/injured?
I will preface this by saying that I am more than happy for people to correct/shout at me if this is not good advice!
If you were able to gain access to the driving cab to tend to the driver and they hadn't or were unable to raise help themselves then the best thing to do would be to hit the big red button with the picture of the train on it on the radio in the attached picture which will connect you to the signaler, I'd dial 999 as well.
If you weren't able to get to the driver at all then calling 999 stating that you are on the HH:MM service from X to Y would be the best option. The emergency services will contact Network Rail to find out where the train is and advise of access points to the railway, as well as stopping traffic if required.
And what about the train if it is full of passengers and an unconscious or seriously ill driver ?
There is a safety concern there
I agree there is a concern, but there are some risks that you cannot fully remove but only mitigate and this is one of them. I don't think it is perhaps wise to get into a discussion of DOO, but rather to take it from the angle of 'it's here to stay on certain lines and there's little we can do about changing that at this point.'
