No those water sprays would seem to be incompatible with cleaning a 650 volt track power system. I'd have thought some sort of train mounted, stiff, rotating nylon bristle, brushes combined with a high power vacuum, hoover type contraption might do it. Like a travelling car wash, without the water.I like the appropriate name of this Company's tunnel cleaning machine, hehe
Don't know about all that water with electric rails though, oops, back to vacuum
You have a lot of rust coming from the trains and tracks that get deposited everywhere in the tunnels as much as passages and zillions of rooms, cupboards, racks, cable trays etc that cannot be easily kept clean. Sometimes I wish people think first about what they would do if they were in the shoes of those they criticise.So the more modern film says they hand clean two hundred meters of track a night if it isn't too filthy and there are two hundred and fifty miles of track. There are 1610 meters in a mile so it takes 8 nights to do a mile, so five and a half years to do the whole system. That video is showing sewer levels of filth down there. No wonder the air quality is appalling.
EDIT:
On re-watching the video or maybe a different one posted by MikelBikel, the narrator said there were two teams so we can correct and half that time to clean the totality of the system to about two and a half years to go around once - but are they that systematic? I doubt it.
He also said they were revisiting an area done only a month ago.... I'm getting bad vibes here. it sounds a bit like the disorganised chaos surrounding the building regulations department and Grenfell Tower's fire. I don't trust these smooth talking spokespersons from TFL, the Civil Service bods who decide on building material safety - or any of them.
I am going to live further into the hills if I can find the right place and I will be preparing every item of food I eat, because I KNOW that all official spokespersons will lie to me. They are far more interested in glossing over the failure and dodgy wheezes they have been up to.
'Here eat this pie. Perfectly safe!'
(sub text and full of trans fats that we know will cause heart disease.)
'Transfats are safe.... They do not exist in nature, but nosh away buddy. It's good for our profits and its really cheap sh it - so it must be good.'
Only 45 per cent of the Underground is actually in tunnels. The longest distance between stations is on the Metropolitan line from Chesham to Chalfont & Latimer: a total of only 3.89 miles. Being London born I've had plenty of tube travel, especially when I was young, and afew years ago when I needed to travel into the centre a few times, I chose public transport including the deepest tube system in preference to driving. But at 88 years old it hasn't affected my life span.What is worse is that TFL proudly show us that archaic, horrible scene, and then expect us to pay to travel on it and leave our cars at home.
Very nice they all are too, no exhaust, silent and air conditioned, all decades ahead of where you critics live.
I've been around for 71 years. During that time, I've seen and heard of many deaths. They all had an identifiable cause. None of them were because of pollution. You'd have thought that if the above figures are true, we'd all know of someone, who died of pollution..Air pollution: applying All Our Health

In the UK, air pollution is the largest environmental risk to public health.
The annual mortality of human-made air pollution in the UK is roughly equivalent to between 28,000 and 36,000 deaths every year. It is estimated that between 2017 and 2025 the total cost to the NHS and social care system of air pollutants (fine particulate matter and nitrogen dioxide), for which there is more robust evidence for an association, will be £1.6 billion.

I don't think anyone has air pollution on the death certificate , but NOx and particulates are known from epidemiological studies to reduce the population lifespanI've been around for 71 years. During that time, I've seen and heard of many deaths. They all had an identifiable cause. None of them were because of pollution. You'd have thought that if the above figures are true, we'd all know of someone, who died of pollution.
Did you actually read that? They didn't show anybody, who died of pollution. They figured out that more people died in polluted cities than in the country, and pollution must therefore be the cause, but they forgot to take into account blocks of flats burning down, murders, traffic accidents, electric cars burning, alcoholism, drugs, depression, suicide and all the other causes that would be higher in a city than in the country. To simplify it, they're saying that if more people die of drug overdoses in polluted areas than in clean areas, pollution must be the cause, and they'd probably argue that it must be the pollution is causing the people to take the drugs in the first place, because not so many people take them in unpolluted areas.I don't think anyone has air pollution on the death certificate , but NOx and particulates are known from epidemiological studies to reduce the population lifespan
Here is one from 2018 that seems to be used in the figures (this is NOx only)

They are more common in London and they include the death of a 9 year old girl, confirmed by a coroners inquest. The medical cause of death is commonly noted as asthma, caused in turn by air pollution as the coroner confirmed in this case:I've been around for 71 years.

Don't be so complacent, you're not 78 years old yet and you've much to learn:

And I would just add that the conclusion of that London Coroner who decided that a child had died of air pollution on the basis of insane propaganda is entirely spurious. It ought to be obvious to any sane person that if the pollution levels at the location of that child's home were so toxic, there would have been a mass disaster with at the very least, swarms of very sick people being admitted to hospital. None of that happened. That child had severe problems. She died because of those, not because of air pollution. That verdict was a disgrace and ought to be stuck off the record.I've been around for 71 years. During that time, I've seen and heard of many deaths. They all had an identifiable cause. None of them were because of pollution. You'd have thought that if the above figures are true, we'd all know of someone, who died of pollution.
He didn't confirm anything other than the girl died of asthma. People die of asthma everywhere. Different things cause asthma attacks, and there are many different things that can trigger them. The coroner didn't use any scientific method or other investigation to determine why she had that fatal asthma attack. It could have been a flea bite from her pet cat. Did he check that? You guys just don't think these things through. You read the Guardian and watch the BBC too much instead of doing the MENSA puzzle book.They are more common in London and they include the death of a 9 year old girl, confirmed by a coroners inquest. The medical cause of death is commonly noted as asthma, caused in turn by air pollution as the coroner confirmed in this case:
"My daughter Ella was a playful, happy child growing up in South East London. Healthy at birth, with a lust for life, she didn’t develop asthma until just before her seventh birthday. A few weeks after her ninth birthday, she suffered a fatal asthma attack. Ella is the first person in the world to have air pollution listed as a cause of death on her death certificate. ”

The only conclusion to be derived from this is that both you and your brother have a hereditary heart condition.Don't be so complacent, you're not 78 years old yet and you've much to learn:
My older brother and I were born in Central London, but at 13 and 10 years old we moved to a coastal town. He was always the fitter and healthier by far in those days. He went into farming and spent his whole life in the English countryside, mainly the West Country. I took a very different route and soon returned to London and have lived here the great majority of my life.
At 78 years old he suffered a heart attack and had to have a replacement heart valve, recovering from that ok but 4 years later went down with bowel cancer. All the usual treatments given, but never entirely successful and he's been dead a number of years.
I also suffered a heart attack, but much earlier at 70 years old, heart trouble being in our mother's side of the family, but I didn't get any drastic remedial measures, just self monitoring and some medicinal control of blood pressure to keep minor attacks to a minimum. This has been so successful that my heart is now much stronger and adverse heart events are now very rare and untroubling anyway, despite my 88 years, at which I'm setting new family records.
So my brother's much more promising health and fitness start in life and his lifetime in English fresh country air obviously didn't do him any favours eventually.
Nor has my net 75 years of living in London harmed me, despite much of it being in central and inner London and almost all of my working days and a lot of leisure time being in central London anyway.
Things aren't always as obvious as they superficially seem

Yes - I had already read that and linked to it in my post - that article was 2017 though and the evidence has "firmed up" since then.Professor Spieglehalter's Winton Centre for Risk and Evidence Communication at Cambridge has covered this in detail, pointing out that the calculation of this figure is entirely made up. Here is a link to the paper. The Winton Centre is a renowned, expert, statistical institution.

Precisely right, just as what you were trying to propose in your countryside life as opposed to my London one made no sense in determining anything at all.What you are trying to propose above makes no sense in determining anything at all.
