I think this is my general point when it comes to these types of event. Historically speaking, the railways have often been able to play to their strengths and been able to deliver when other modes of transport have not. I think, in a large part, this reflects a number of concurrent issues around investment, infrastructure age and the many many issues posed by fragmentation during franchising.
From a personal perspective, the risk tolerance of the industry is what I've noticed change the most and I do think that's a real shame, as it prevents rail as a mode from shining through when it really can excel itself compared to, say, a bus service or air travel. All that said, I think there is something in comments from other that tolerance to disruption has reduced amongst users (and perhaps theres an expectations management exercise to be done there). I also think the industry's approach to image management has moved more to delivering a reliable/regular service when we can, rather than delivering what we can all the time.
I appreciate the arguements on both sides and I do think, sometimes, on these threads theres a tendency that I'm certainly not immune to, of making the conversation into a binary arguement of run everything vs cancel everything. This sometimes results in arguements that venture toward the ludicrous, which quite clearly is not really what either side is trying to say (generally speaking).
The reality is foul weather puts most people off traveling, so whether trains run or not, the impact is always going to be lesser than during, for example, a fatality just outside a major hub on a peak summer match day. To that extent, whatever decision is taken (pre-cancel service or not), less people will be affected, but I do think that often leaves those who have very little choice but to travel (and we can't ignore the fact that these are often the less socially mobile members of public), with little choice and indeed pushes them towards difficult decisions around modes of transport etc. Maybe the railway should do more to try and meet its obligations as a taxpayer funded public service, but again, if your risk tolerance is low, there isn't much room for maneuver here.
I do believe that the industry has the potential to do more and be more adaptive, but without atleast some modest investment or a preparedness to be less risk averse, there is little room for maneuver here.
If theres an offer for a visit to control packaged in there, I'd happily take you up on that (though, maybe chose my words carefully)!
