There are various reasons for this, ATO trains seem to be covered above, but it can also occur because of rail gaps causing motors to drop out as trains accelerate. Northwood on the south is particularly noticeable for this as trains cross the points which access the siding. Northwood siding is likely to be removed as the land is earmarked for Houses. Sorry to prolong this excursion from the Jubilee line. I think at Northwood the electrified siding is to remain, also the crossover that allows trains to go south from the northbound platform. So the associated conductor rail gaps wouldn't be affected by housing development.

Seeing mention of "fully air-conditioned", has anyone ever only claimed "partially air-conditioned" I wonder. :-)

For more clarity it's said like: "Jubilee line, the train now approaching is for Stanmore, please stand back from the platform edge." Used to say "from the platform edge doors." I don't know who the voice is, but it's amusing to be told to stand back from the platform edge at a PED station. Why's that, might the train blow the platform screen over?

Stabling in platforms such as Moorgate Met requires traction current modifications to allow all-night power for train testing, and signalling modifications to avoid loss of train detection whilst the train is powered down. Depends how many trains you stable at a location, the train configuration and the staffing. There are locations today with regular outstabling where train prep is completed before traction current is switched off. Also no signalling mods needed with LUL traditional signalling and even the new SSR signalling has a facility to allow for this at specified locations.

Interesting special service running today due to Engineering works. Circle line from Edgware Road to Barking via Victoria. Have trains labelled Circle ever headed out to Barking before? I hadn't noticed any but I guess it may have happened for similar reasons. Obviously I know they are the same trains and same drivers as the H&C so it makes little practical difference except they will be going via Minories junction instead of Aldgate Junction. Do Circle/H&C drivers have route knowledge for that? Or would District Line pilots be used for the stretch between Tower Hill and Aldgate East? I'm pretty sure that the Customer Information System (CIS) 'trip' on the trains calls the eastbound trip as District line, while the inbound from Barking towards the Circle is announced as Circle line. Maybe they are not using that special eastbound trip on the CIS if both are being called Circle. They'd have to change it from Circle to District at some point though.

Some folk on the FACT project unofficially called it Fully Automatic Railway Train. And abbreviated that of course... It was always actually manned but could operate as described. There was nothing other than the door interlocks and the Signalling to assure safe departure. And I'm pretty sure it didn't carry passengers. Some of the extra kit was mounted in the saloons of the DM cars for simplicity of the demonstration.

The people swarming all over the tracks at 6:05 was quite disturbing. It's not the lack of hi-vis that's so surprising but the fact most of them are working within platform grounds and without much by way of Lookouts. I don't recall it ever being permitted to work on track in platform grounds during Traffic Hours because there's no immediate usable Place of Safety to move to. Anyone aware of when that was stopped? Seems amazing given the relatively poor sighting time due to the curve and the fact that both tracks are in use as seen by the train on the other road shortly afterwards. And of course these trains are in ATO, not manually driven.

Err? The article doesn't say the whole bag was outside the doors, just a trapped strap. Pull it? Push back the pushback door leaf to help? This was a 95TS after all.
On the non-pushback S stock I've seen someone get a strap or coat tail stuck at King's Cross and with some late running going on, after the T/Op had reset the Sensitive Edge, they told the passenger to stop pulling and they'd have to wait until Aldgate! Justice done I thought.

Hammersmith (District & Piccadilly) looking east perhaps for the main picture? And might the left inset be at Newcastle?

Isn't picture C actually from a Jubilee line train? It certainly seems to be on the Jubilee track which Met line can no longer run on, and the window surround looks more like 96TS to me.

The ride in the DM car ends must indeed be marginally worse than other car ends, but whilst you may be able to instrument and record that difference, I doubt that the majority of passengers could tell the difference in a blind test. In any case I am pretty sure it still passed the relevant type test. I ride at the car ends sometimes and it hasn't bothered me.

South Acton is the only one of the four to include the nom de guerre of a Bronte sister... Whatever the right answer, it should be the Bronte one instead! Brilliant.

Does anyone know why the eastbound train describers at stations near the Hammersmith end of the HC&C line are so intermittent? Very occasionally they show an actual destination and time, but more often say 'check front of train', or the hugely useful 'Hammersmith and City Eastbound'. The westbound indicators seem to work well (although it's not the most difficult of jobs getting the destination correct). The default to "Check front of train" is used widely on LUL platform DMIs when things go wrong. A suggestion to fit the trains with a destination of "Check platform indicator" wasn't popular... Sorry, back to the topic.

No 'e' in South Acton. All the others have 'e'.

This is a word one, you don't need to know anything about the actual locations. Well the original question doesn't mention any odd one out, that was only mentioned later. The original question also mentions 'four main ones' which is odd. If there is an odd one it seems to be reduced to North Wembley or South Acton. North Wembley is the only one with the second part starting with a letter alphabetically after the letter of the associated compass point and abbreviated is itself a direction. Ec, SA, WS, NW.

Not favouring West Silvertown, but from the information and pictures in the thread it's the only one with no brickwork. Sure that's unlikely to be the answer but...

West Silvertown is the only one with the railway and platforms above street level. Also the only one first opened in the 21st century. South Acton is the only one that used to have a London Transport (now LUL) service but doesn't now. Tricky, I'm sure we can find something to make each of them the odd one out!

+1 for South Acton, although it's changed a lot since last time I used it! So the odd one out is West Silvertown which is in East London, all the others in West London.

B is not Kenton, but you're not far away. The image is unmodified. Looks like it could be North Wembley. So is the link the four compass points? Meaning that D should include 'south'.

As of this week the last train has returned from ATC installation in Derby and for the first time ever, all 192 S stock trains are in London.

S stock does handle low voltages properly. But once the car is 'gapped' there's no energy to keep it motoring! Also, once it's above about 20km/h there is a feature to stop each pair of cars motoring in turn at the appropriate position along the track after the first car detected a gap, thus reducing shoegear arcs on subsequent shoegear sets.

The DC Sectionalisation Gaps are near to Northwood Sub-Station which is much closer to Northwood Hills. I think the current rail gaps just south of Northwood are just associated with the crossover points and the points leading off into the siding. OP describes "lack of traction" so may be they meant poor adhesion and wheelspin instead? If so, may be rail head contamination from grease at the points mechanisms?

That other image that you've revealed is definitely not Holloway Road! Although when you click on it the completely different image that opens is what I presume really is of Holloway Road.

+1 for Willesden Green - Kilburn. You can also see the TBTC signalling loop cables on the two middle (Jubilee) LUL tracks and of course not on the Met tracks.

Not surprising; they may well use the same compressors as the Bombardier Movia, the family to which the S Stock belongs. I wonder whether they are the same general type... How many compressors do Class 345 trains have? Two is barely enough on S stock once the compressors are coming due for overhaul and their efficiency goes down.

It's not about the driveability of S stock using the Traction/Brake Controller. That gives very good fine control at least as good and maybe better than the A stock. The driver of that train in the video was very probably standing up to view the signal down in the six-foot. Viewing angles seated in an S stock are nowhere near as good and that's one reason why most drivers wouldn't run so close up to the signal before it cleared. Also if that signal had not cleared as the driver probably anticipated by viewing where the train ahead had got to, they would have got tripped. Skilled judgment, but not quite as trained!
