On the Victoria line, which is all underground, the temperature is related to the heat input.
In practical terms ALL the electricity used eventually comes out in heat and as has been said each customer represents about 100W of heat.
On the day (approximately) that the last '67 tube stock is withdrawn, regenerative braking will be able to be turned up to the maximum and whilst the Victoria line train service runs the same timetable, the electricity used wil drop by about 25% to 30%.
As the timetable is expanded to a 37 train peak with higher acceleration rates, electricity used will increase again and will eventually be higher than it is today. Also the service will be better and so more people will be attracted to the service, so more heat.
Hence making the tunnel fans bigger is "a good thing"!

Back to the topic: where is that pesky Train 2 hiding?

Any more news on this? 3 weeks later and still no test train? :-(

Wow - big delay. Hopefully we can get trains with proper ventilation by summer 2010 at least.
(I was naively hoping they'd be here for this summer's Victoria line cook-off)

I think people may be overestimating how much difference the ventilation makes... It isn't air conditioning and the stations will no doubt still be like ovens.

no, its not air conditioning, its forced air circulation, its bascily what we have in the cabs on the vic line already. Its not amazing, and on a HOT day you will still be hot, but the fact that there will be a airflow around the carriage should make a difference :-)

I am hoping (perhaps over optimistically!) that with the forced air, the TS09 will feel like on a Northern Line 95 stock, where the forced air seems to make a huge difference.
Perhaps in a week or two we will get to find out...

The forced air in the saloon on an 09ts should be better than that on a 95ts. The airflow has been directed in such a way that it moves in a circular motion around the carriage in order to benefit those both seated and standing. Ultimately though, it is not air conditioning.

Sounds good. Looking forward to trying it next year (touch wood!)

Peeved of Canterbury: the news article I heard on the radio yesterday suggested the trials were going to be actually on the Circ.

Given that we've never* heard the outcome of the trial to see if they fit on the Picc, it would be an expensive (in terms of time and money), not to mention rather pointless exercise to do that!
*At least I don't remember hearing it.

On the circle? That doesnt seem to make sense...

Some confusion here: the news reports two days ago were of the (air-conditioned) S-stock trials at Old Dalby, not to be confused with the 2009TS trials on the Victoria Line.

I'm glad you cleared that up, I was really scratching my head here! So, to clarify the situation for everyone:
'S' Stock for Metropolitan, Circle & Hammersmith, and District lines. Roll out 2010 onwards with full saloon air conditioning. 09ts for Victoria line. Roll out 2009 onwards with a modern, non conditioned, forced air ventilation system.

I'm guessing that on the new 09TS it will still be possible to open the slidey windows on the end carriage doors for ventilation, right?
(And do LU refer to these as "drop lights", as is the case on mainline railways?)

Had a ride on the public 2009ts just now, very nice. A lot lighter and having the air vents at head height helped it feel cooler. I noticed that a lady's hair in the centre of the car was fluttering around as if she was stood next to the drop light (which yes, it does still have). I found it quite interesting listening to the reactions of the "normal" people travelling, three people were wondering what happened to "that ground-water cooling thing" and a few others were talking about being able to use their phones. MRFS asked me about the acceleration, so I've put two vids online, one of the old stock leaving Euston, and 16 minutes later the new stock leaving (the 09ts was the next train). Clicky OldClicky NewOne interesting thing I noticed is that the external displays when heading north read: Walthamstowe <scroll> Central <scroll> 267 <scroll> Not sure of the need for the train number on a display intended for the general public who have nothing to reference it to, and at one point I glanced up and the train said "Central" on the side; I thought someone had messed with the software and it was going to Ongar!

Interesting - thank you for the videos - I can see ¾min being shaved off in places. I could apply Furgutts Construction and work out the acceleration. Was there really an 'e' at the end?

Last orders plus drinking-up time at Euston, then a gentle bimble to the platform for the south-bound. 0025 Northbound through Green Park, though there was a 15 minute gap in the service in front of it.

One interesting thing I noticed is that the external displays when heading north read: Walthamstowe <scroll> Central <scroll> 267 <scroll> Not sure of the need for the train number on a display intended for the general public who have nothing to reference it to... For the benefit of protection staff on platforms who are waiting for the last train (including empties and engineering workings) to go through before they place themselves in harm's way to check the current? The 67TS have a train number display separate from their destination blinds, but that's another thing to maintain, and I'm sure combining the two saved a few quid here that someone was quite proud of - provided the cycle rate of the display is fast enough to read all of in the time it'll be within sight!

Does anyone know if the end of carriage windos slide all the way down?

Earlier I wrote: I noticed that a lady's hair in the centre of the car was fluttering around as if she was stood next to the drop light (which yes, it does still have). By drop-light I meant the windows in the car-end doors. They drop to the same height as on all the other stock; that is high enough so you can't fall out, but low enough to rest your elbow on.

So it goes down to the same as the 1967 stock? Hope its not restricted like on the pic line. Not all windows go to the same height

that fan sound on the 09 sounds identical to the one on the 95 stock or is it just me

Not sure of the need for the train number on a display intended for the general public who have nothing to reference it to, So that passengers can quote it when making a complaint?

The number was added to the leading cars bodyside dot matrix indicator in order for staff to be able to see the train number when stepping back without having to walk off the platform and peer around the front of the train. I know this because I was at the meeting in Derby when we decided to add this feature!

Ahhh, I hadn't noticed that it was only the leading (and trailing) car that displayed it, that makes a bit more sense. TVM.
