Of course not Unless you measured every breath that everyone took, you must use gathered data with some kind of statistical model. But models tell you exactly what they are designed to tell you. That certainly can be true, particularly of more complex models - or ones that depend on dubious or unproveable assumptions, but as I pointed out in the response you quoted, there is no other practical way. In this instance, the model is fairly simple, and if you can find any dubious assumptions (e.g. that all problems are caused by fumes - ignoring other particulate generators), anyone is welcome to point them out.

Can anyone point me to research that qualifies the amount of PM 2.5 particles people actually breathe in, rather based on models? Of course not Unless you measured every breath that everyone took, you must use gathered data with some kind of statistical model.

Pass, I just put the registration number into the checker and it said I didn't need to pay the fee! So, will you be driving it to the Coronation Special?

From the London councils site:
"In London, 9,400 premature deaths are attributed to poor air quality and a cost of between £1.4 and £3.7 billion a year to the health service."
Even if only 20% of those deaths were attributable to car originating pollution, that's an awful lot of deaths over 15 years.

Remember there is a pending court case challenging the ULEZ.
Perhaps Bromley will be turned into a giant car park.

That's a shame as it's the compressors that were (to my mind) the standout thing about the sound of the stock - mainly because of the sounds they made when the train was stationary.

Does this train have the same sound as it did when in service, or have changes necessary to comply with current standards meant that different 'unseen' equipment has had to be fitted?
Also, possibly a stupid question, in that water is obviously 'a drink', but when they so no food or drink on board, does that include plain water?

Thanks, DStock.
I'll look out for the indicator next time I'm there. (I assume that it's visible from the platform.)

Looking west at Shepherd's Bush Market, I noticed that, on each track, where the 'outer' current rail reverts to driver's side, there is also a gap of ~ 2m in the centre current rail.
Although it was the same layout on each side, the gaps were offset one from the other.
From the cabling, it appeared that supply continued across the gap.
Can anyone say what the purpose of the centre gap is?

The Picc is definitely the Misery Line at the moment in my book. Always nice to know when you’ve got a flight coming up.

Perhaps they should open the naming up to the public, and then we'd have the 'Liney McLineFace Line'.

Nine Elms is given the title 'Station' after the name, but not so with Battersea Power Station. Why on earth would you add station to a station's name (unless it was the near site of a very prominent fire/police/power station)? How many railway stations in the country (of any type) have 'station' as part of their official name?

Of course, if they don’t go for a theme, they might even retain the Goblin name.

At least if they give the lines proper names it will get rid of the ‘Goblin’, which I find more annoying than ‘Wimbleware’. Particularly as people so often refer to it as the Goblin line, which yields Gospel Oak to Barking Line line.

Name them after ancient kings. I like the sound of.the ‘Æthelred’ line.
Of course, there might be delays.

Slightly off-piste: why the TfL obsession with calling the Overground the 'London Overground'? It's not like there are Overground networks or lines in other cities... London Trams makes sense cuz there are numerous other UK tram networks. The Underground is not labeled as 'London Underground' is it? Calling it 'London Overground' everywhere is unnecessary and too long. Probably to differentiate it from the rest of the mainline network. I’ve similarly wondered why the BBC insists on referring to the London fire brigade/ambulance service. Which other fire service would anyone assume would attend a fire in e.g. Notting Hill?

It certainly isn’t just Earl’s Court. It regularly happens at, e.g. Hammersmith and Edgware Road.

Feel free to let me know your thoughts... I believe tfl have royally b*ggered up contactless. Whichever method you use, you can't get all the discounts to which you are entitled. With Oyster, you don't benefit from the weekly cap. There's no excuse for this. It's just a matter of post-processing the data that they have (and indeed, send you, if you have an Oyster card account). With CC/DC, you can't add railcards. Again, there is no reasonable excuse for this. If they can instantly access databases to validate CC/DD/Phone payments, why can't they have a server to interrogate to determine if a particular card is linked to a railcard? I have not yet heard a plausible reason for this from someone who understands the IT involved (although I've heard many spurious reasons from those who clearly don't).

Largely off topic, but changing form St. Lazare to St. Augustin on the Paris metro (A change that is marked as 'linked' on the map), you have to exit and re-enter three times. (You also have to walk for about ten minutes and negotiate multiple short sets of steps, but it is all underground/covered.)

I've noticed that the DMIs in the deep level stations on the JLE seem to be in worse shape than the ones at the above-ground ones I wonder why that is It’s the pressure. It gets to them.

This is why I wondered if the circle line behaves in the same way. The line details after than and the H&C diverge could lead to more 'padding' being needed on one compared to the other.

Is it just H&C trains that do this, or do circle line trains behave in a similar manner?

As trains going out of service to depot will still be checked there is really little risk where a passenger should be any of the above. I cannot make any sense of that. To whom are they going to call? Are there myriad LU staff milling around the sidings to hear their calls? Perhaps redeploy a couple (no, that does not mean exactly two) to check the train before it leaves service. It's only hyperbole if someone obdurately insists on taking the phrase literally. I didn't think anyone would be daft enough to think that was what was implied. Are you sure you know what hyperbole actually means? It does not mean a something which (you consider) might be a mild exaggeration, and with which you disagree, which seems to be the sense in which you are using it. That is irrelevant. The salient fact is that it relates to a train being out of service with passengers on board. I thought I'd explained that, above. The big difference is that LU cannot stop people acting foolishly on in-service trains (where inter-carriage doors are presumably necessary for fire safety reasons). What they most definitely can do is ensure that passengers are not unnecessarily placed in a position where they are more likely to attempt to use the inter-carriage doors. You know, as they do at the moment. Indeed, and LU, on balance, decided to implement a checking scheme to mitigate the problem that lead to a fatality. Tat was a good move on their part. Now they have decided to that it's too expensive (in terms of money, or time). So what was once a reasonable safety mitigation is being dumped because of cost. Good luck defending that should it ever become necessary. LOL, and LU may not find such a case as easy to defend as you seem to consider it. And all this ignores the much more pressing problem of drivers being attacked/abused by drunk, angry, passengers.

I presume you mean for railway, but just in case, back in the DOS (Disk Operating System) days, it also stood for Terminate and Stay Resident(s).
