I personally feel that is partly down to how risk averse we have become, people no longer feel they need to take responsibility for their own safety or actions because the H&S overlords are looking out for them.
There's lots of studies that prove - not just in a railway context - that people generally underestimate the chance of bad things happening to them.
Obviously I do not know what alternatives, if any, were discussed. The railway chooses not to communicate that. Their communication is limited to “we’re closed on Friday, your problem not ours.”
Nor would they discuss various options that weren't taken forward as it would be irrelevant for relevant passenger information and would have the impact of confusing the message. I don't necessarily like the fact that alternatives - besides travelling on a different date - are pretty much non-existent or people have to try and work out what their rights are (such as having alternative transport provided or accomodation in extremis), but I do appreciate that trying to arrange all of that at short-notice during extreme weather is extremely challenging for those whose responsibility it is (staff normally trying to manage the disruption already)
How should it come across? Perhaps they could explain why they make a decision like this 48 hours in advance based on nothing more than a well-informed hypothesis. Why can’t they wait and see what actually happens tonight first?
Because it gives the opportunity for everyone to plan in advance. To wait until later is often too late and often over-promising on what can realistically be delivered. I don't really think it is fair to call professional weather forecasting and modelling a "well-informed hypothesis". Maybe 40 years ago, but not now.
I can appreciate why they closed early this evening and made that decision early. I cannot appreciate why they are closed tomorrow all day based on nothing more than a forecast which may or may not happen.
I don't really understand how you can't understand the parallels between the two decisions. The rationale is generally the same - it's about making decisions early. Now I am not saying that these decisions will be correct 100% of the time, but at least there is advertised certainty about what will be open rather than having a go and then running into disruption and having to amend services at short-notice, which generally has a more disruptive impact.
If the snow doesn’t fall as expected tonight then we’re going to be in the position tomorrow that schools will be open and employers will be open but the railway will be shut. Sorry, too late to change our mind now, no trains. We’ve seen it happen so many times before where the weather isn’t as bad as forecast, or doesn’t land where they thought it would, but the railway still doesn’t operate anything.
On the contrary, we have also had very many of these threads on the forums where the railway made exactly the right call on the information given and to instead do as many forum users have time and time again suggested would have stranded thousands of passengers on multiple trains on various routes. Even running trains with best endeavours within severe disruption can spiral because of all the connected crew and stock issues that it causes and can cascade into the next day's operations. These things are all interconnected.
Every couple of months we get these threads, and it is pretty much always 'damned if you do, damned if you don't'. It is frankly a dereliction of duty for Network Rail and TOCs to not take such forecasts seriously, understanding the constraints in the infrastructure and resourcing that is available. You can say that there needs to be better response resourcing, control staffing or better climate resilience and I doubt many would disagree, but that doesn't help what is happening right now, today or tomorrow where the real world requirements have to be taken into consideration and there isn't going to be a massive enhancement budget coming any time soon from the DfT.
