This.
You have your conclusion before your thinking, I suspect.
No, I don't. Quite the opposite in fact. My post illustrates the thought processes involved. If my analysis had suggested that there was a significantly high level of major accidents/terrorism/gang warfare in tube stations or tunnels that justified having several non-ticketing members of staff milling around in the station 18 hours a day, 364 days a year, every year, then that would have been my conclusion.......
Bottom line is, you're guessing.
I sure am. It's called an educated guess. A hypothesis. Scenario analysis. But I'd certainly be interested if you could tell me how it would be possible to forecast the likely future need for staffing levels without a) examination of past precedent, and b) guessing future needs based on that precedent and any future-specific factors.
I'll revise my opinion if you have any background or qualifications that would enable you to assess situations like these for safety implications. It's quite a specialised area. Do you have any such credentials?
I am very sorry to have to tell you that I don't. What is the appropriate accreditation? Do you have it? And I assume (correctly?) that you believe my opinion doesn't carry any validity unless and until I have this qualification or background of which you write. I also assume (correctly?) that in your view it's pretty much impossible for someone without an underground railways health-and-safety background/qualification to use general logic, reasoning and information to make an educated and informed argument on this issue. That's your prerogative. I, of course, would disagree.
Or links. They're good. Do you have any of those?
I am afraid I don't have any links to all the major incidents (accidents with multiple injuries, terrorist atrocities, gang warfare, etc) that
haven't happened on the London Underground network in the past 30 years. I apologise for this.
ETA: Apologies for the use of the word 'Know'. Your use of a blank statement of fact with no equivocation fooled me.
I had written two things in the post you're referring to.
Firstly, I wrote that
"the probability of a genuine serious emergency occurring in any given tube station, where the instant availability of numerous LU staff would make any significant difference to the outcome, is so small as to be almost negligible." That is a statement of fact, not opinion.
But I then added my
opinion to this. And, interestingly (in light of your barbed comment above), I prefaced the comment with exactly that (my bolding for clarity):
"In my opinion, it's a provable fact - in a good-business-sense-while-covering-off-passenger-safety-apropriately sense - that all central London tube stations are grossly overmanned most of the time. The overwhelming majority of situations requiring staff intervention concern either individual passenger illness or accidents, or criminal acts of some kind. In either case, it takes no more than one or two members of staff to attend."
But there, as they say, you go........
