well actually, in some circumstances, it is.
the TOCs have a duty of care to their passengers to keep them safe. When there is a weather forecast that predicts a risk to life from flying debris etc., then it is perfectly reasonable to say a) do Not travel and b) we won’t be running a service.
So that comes under the banner of being possible to run a service, it's not a TOC controlling people's decisions - but again and as has been pointed out repeatedly before - the wider social implications need to be considered. Stop the trains and people turn to other forms of transport.
Take myself, I book on at 1500 today, I'm done at about 0030. I can't take the train to work as my finish time is well past the last train home. Despite the warnings, I also can't work from home, and I have no intentions of enduring the furore of a driver manager or losing a daily leave for not turning in.
Personally, given the choice, I'd much rather be on a train. When I'm at work, I'll feel far safer driving the train than driving my car to work. I think thats also a sensible risk assessment. Trains are generally a great deal more substantial than cars, and I'd rather have a good couple of hundred tons against a tree than my cars 1.5. It's also fair to say a tree falling on my car will likely kill me, whilst a tree falling on the train will likely be far less life threatening.
Thus, the point I'm making:
TOCs are responsible for running a safe service, but their definition of "safe" needs to bare some resemblance to that of their customers, otherwise greater risk is created, taking a holistic view point (obviously canning services is bad for your business too).
Whilst there's much noise made about prioritising safety by not running trains, train crew are still expected to turn in at work, along with all those (as the poster below) who can't work from home. By canning services carte blanche, more risk is created all round.
Risk is a part of life and sometimes we have to accept that there's no perfect, 100% risk free, solution.
Of course I would. I have planned for massive disruption and this is why I drove to work today.
But I was replying to the OP about having a choice to commute to work. I work on the front line in a busy London hospital and patients rely on me turning up to work. I can't choose to do my job at home.
Completely agree, it's just a good job we don't live in Scotland as there'd likely be no service (or chance of getting to work) at all!
