Merseyrail guard jailed for manslaughter

Very valid comment, people don't take enough care of themselves these days, a result of the 'soft' approach to life fostered in our politically correct H&S conscious society by an overprotective generation in the last decade or so.
Drunks have been around ever since alcohol was discovered and existed on the Underground long before I began my LT career. I saw plenty of drunken tomfoolery in my many years on nightshift, idiots playing 'chicken' at Whitechapel running across the tracks between the platforms while awaiting last trains and others pushing each other around on the end of a Northern platform at Moorgate until one fell onto the track as the last train was approaching. For that kind of behaviour idiots deserve what they get because they should expect to come to some harm.
I was also around when fatalities occurred to the alcoholically impaired, one was due to a fall down the stairs at Blackfriars.

For the former I'm afraid I have always had a can't care, won't care attitude to such wilful disrespect for danger in terms of the outcome for the participants, particularly as the drivers especially are traumatised by such events whether accidental or deliberate.
For the latter, accidents can and do happen and that's what the mitigation of risk is there to prevent.
While drunkenness is not to be condoned there is no doubt that most of us have been there at least once and done something stupid as a result in our lives but that should not normally result in death and rarely does because inherent commonsense saves us from ourselves. For those times when that is not enough we have to relay upon safety systems to prevent avoidable accidents and have enough commonsense to trust and defer to them eg waiting for the green man at a Pelican crossing, taking a cab home from the pub instead of staggering along unlit country roads at midnight in a dark suit, or relying upon LU staff and safety systems to get us from A to B safely.

Having been in cab myself on many occasions on late turn I wouldn't be a driver for all the money in the world, it can be a thankless task especially when having to detrain the passengers because the train has become defective. Even as an observer one could feel one's blood pressure increasing on approaches to crowded platforms with so many people so close to the platform edge. I have to say for those that have never experienced it, I would rather be in a tube tunnel dealing with signal failures with trains approaching at full speed, as I sometimes was, than being a driver at any time of day because on the balance of probability the odds against having a nasty incident are so much better!

For my ten penn'orth the answer is to put staff back on the platforms unless or until all platforms are gated, this is long overdue and one part of the system where safety has been long overlooked. PEDs are not the answer, being expensive and complicated to introduce but simple three foot high gated barriers 600mm from the platform edge would be affordable and installable without disruption to service. They don't have to be overcomplicated masterpieces of engineering design, they simply have to be fit for purpose and functional. One can't help but think how useful all the door motors of the recently scrapped stocks might be now! Once gates are fitted I wouldn't have any concerns at all about idiots vaulting them, on their own head be it, it is the sort of thing that should be enshrined in law rather than protecting the wilful against themselves.

As I was a one time installer of LU CCTV systems I know their limitations, with the best will in the world they will never be more than an excellent aid to crowd control and have to be supplemented by other safety systems. In the past the 'other' safety systems were the station staff but though they have been disappearing off stations for decades now they have not been effectively replaced by anything else.
