The Electrostars are all designed for outer suburban/regional journeys (except the 378s, which are technically "Capitalstars"), whereas the 345s and 710s are designed for the inner suburban/metro-style services that they run on. The 730/0 interior is certainly very pleasant and well-suited to regional journeys.
I agree that they look better, but I still mourn the loss of cab-end gangways, as ugly as they look on the 701s/720s (TfL stuff doesn't need them because they don't couple very much), as ugly as they look. I think the 730s actually wear them quite well, to be honest. Aventras are certainly a lot lighter, partly due to their big-word fancy light bogies.
I don't understand the lights looking dated on the S stock. Do you mean the light bulbs themselves not being LED, or the light holders? I think the holders are a brilliant piece of design vs the white plastic on other stock that always gets full of dirt and muck. I was astonished how much brighter the 96 stock got when they cleaned the holders, that won't ever be a problem on the S stock design. LED bulbs would be nice though provided they aren't too cold in hue.I think the only parts where the S Stock is really showing its age are the seat covers and the lighting, but otherwise they feel much more modern than the 2009TS, despite being of similar vintage.

The seat covers could do with a refresh though, absolutely.

The biggest difference between Electrostar and Aventra interiors is the former having more segregation with things like gangway doors, more differentiation in the area around the (external) doors, etc.The 730s interior surely is very pleasant but the Electrostar era interiors, despite feeling more closed in, also can feel more comfortable. Maybe it’s a compromise between spaciousness and comfort.
But even so I think aventras are quite conventional looking. Most modern uk trains seem to look conventional I think, since probably the 10s. I guess because it guarantees reliability. If a company were to design a new train, without being too traditional, or using standard looking parts, the Aventra can look a bit dated as well.
That sounds familiar; something to do with "reducing the unsprung mass" (whatever that means), I think?I’ve heard the 24ts also use bogies integrated in the body of part of the body weight, am I correct, to reduce track wear I think.
The S stock design was completed in 2006, at a time when LED for general lighting was in its infancy. Obviously a mid-life refurb can include an overall change of the lighting, but the trains provide the service needed, are exceptionally reliable, and the old saying, 'if it aint broke etc. ...' goes. There might be an exception to repair seats that have had the most wear, but that could probably be arranged at minimal disruption.I meant the lighting not being LEDs.
UK rail is faced in many areas of increased patronage where all the easy changes have been deployed, e.g., longer trains and more frequent services. Stock used for commuter services is especially overcrowded, so the style of interiors in recent designs has accommodated demand by more standing room and improving the ease with which they can be accessed and left by passengers. Thus through gangways, wider in-car gangways and fewer seats are feature for new stock procured for those mixed type of services.The biggest difference between Electrostar and Aventra interiors is the former having more segregation with things like gangway doors, more differentiation in the area around the (external) doors, etc.
Unsprung mass is damaging to track, thus better and more compliant axle suspension means that the bogie mass is not shock inducing.That sounds familiar; something to do with "reducing the unsprung mass" (whatever that means), I think?
I was thinking a bit about this. 92 stock design, ignoring the wear and tear, actually seems more modern than 95/6 stock. The widths of the doors are similar size to 09 and 24 ts, whilst 95/6 stock has similar width to older stock such as 73, but a little wider. Idk if it's cause of the 83 stock initial proposals that were cancelled, but the carriage length being long is actually the opposite of 09/S and 24 stocks, I think. The seats despite less comfortable I think are designed for more floor space on 92 stock, which newer tube stock seem to do. 95/6 stock seem to have seats a bit more designed for comfort like I assume with older stocks, though it doesn't maximise floor space.I would assume more modern stock took practicality, aesthetics wise, from the 95/6 stock, but layout from the 92 stock.To me, the 1992 stock is still the most futuristic looking train in LUL's fleet(especially the 482s with NSE livery).
Something I just noticed looking at 96 stock is that the doors also sometimes don’t all close the same time. I think this is something I would’ve found annoying about the s stock but I think the reason is just that it’s more obvious on the s stock and probably the upcoming 24 stock. I think that maybe the s stock has individual door chimes so the lack of sync in all doors opening is sometimes obvious whereas I only observed this looking at a 96 stock as the door chimes are probably for the whole train.I find s stock glitches annoying. Such as when the orange door open indicators don’t work for one carriage. Or the internal door light doesn’t switch off. I’ve seen the latter on the 09 stock as well.
The S-Stock's cousin - Stockholm's C30. Differences in even just lighting aesthetics do make a bit of a difference ...

As an aside - those C30s are awfully quiet.
They're not related at all. Train manufacturers use the same brand name to designate platforms which have nothing in common. The S Stock and the C30 are branded as Movia trains, and that's the only thing they have in common. All Bombardier metros were branded Movia, and obviously most were very different to each other. The same goes with Alstom's Metropolis, Siemens' Inspiro, and most non-modular train platforms worldwide.How closely are these and the S Stock related?
I can see the windows are a similar shape and layout but not much else.

Design-wise they're based on the C20 train, which is an ADtranz design.Ah fair enough, though looking at some external photos, they do share some vague similarities around the windows and general body shape.
Did ABB Transportation become ADtranz? When exactly did this occur, what it when ABB merged with Daimler-Benz transportation and then the name was changed. I am interested to know if the 2009TS for the Victoria Line had any similarities with the 1992TS for the Central Line built at the same plant but by ABB 20 years earlier?
Was the “Movia” family originally an ADtranz design? Being a Bombardier design when they took over ADtranz.
The light holders are problematic because bugs can get in through the holes, but die within the fixture and rest on the holes rather than falling through them!I don't understand the lights looking dated on the S stock. Do you mean the light bulbs themselves not being LED, or the light holders?

Why are they like this? Is it to do with vandalism? I know some electrostars feature this too.The light holders are problematic because bugs can get in through the holes, but die within the fixture and rest on the holes rather than falling through them!
I think the holes were in response to light holders in the style of e.g. the 95/96 stocks always getting dust and grime trapped in themWhy are they like this? Is it to do with vandalism? I know some electrostars feature this too.
Although the 2009 stock has the plastic casing. I’m assuming this doesn’t matter as much with led lights???I think the holes were in response to light holders in the style of e.g. the 95/96 stocks always getting dust and grime trapped in them
S stock was after the 2009 stock I think? I just picked 95/96 as my example because I'd used them this morning and knew they definitely had the plastic casing!Although the 2009 stock has the plastic casing. I’m assuming this doesn’t matter as much with led lights???
Yes s stock seems a bit more similar to 24 ts with small stuff too like the door type, the armrests.S stock was after the 2009 stock I think? I just picked 95/96 as my example because I'd used them this morning and knew they definitely had the plastic casing!
The S and 2009s were constructed at basically the same time. I assume the lighting is different, as on the much lower 2009 stock, the lights are within touching distance of the passengers, and light shades with holes in would be considered dangerous.S stock was after the 2009 stock I think?

Scratching skin I assume especially as it gets older and wears out maybeHow?
Their air cooling systems seem pretty poor this year compared to the Elizabeth line. Do they need maintenance?
No I think it's just like that. I remember them not work super well in 2022 when London got to 40C. Also one year I had bad hayfever, I noticed I would stop coughing in Asda supermarket or a Class 700 or Class 350 I think even. However my haayfever symptoms were bad whilst in an S stock or class 378. I think the ventilation systems are built to a different spec.Their air cooling systems seem pretty poor this year compared to the Elizabeth line. Do they need maintenance?
Yes I'm hearing the S stock air con temperature is cooler than the Elizabeth line.I noticed the same myself a couple of weeks ago, it certainly became more obvious when I later got on a District Line train that was like a fridge in comparison.
