I have just emailed TFL about the ventilation and inaudible driver announcements on the 2009 stock - will post ahen, and if, I receive a reply. I have put a few technical words in the email that the average passenger wouldn't use, so hopefully I'll get more than the average passenger "fob off" reply. Watch out - we have rules about bumping threads in 6 months you know ;D .

I just got a patronising reply back from LU telling me that the Victoria Line's tunnels are warm due to the line running entirely below ground (knew that), so this begs the question why then force said air into the 09TS passenger saloon using fans? At least on the 67TS the tunnel air enters through vents mainly during motion and is therefore cooler. The truth is LU have realised there is a design fault on these new trains, the air is apparently being drawn in from areas adjacent to warm train equipment and they have not so far been able to correct this. "I think we have bought a pup" as a VERY senior Vic Line manager said to me recently...

Used the Vic again this week: saw one going the other way but still not been on one.
From what I read on here, I've been lucky!

I had an unlucky encounter with train 5 today at Brixton, it was a total scorcher compared to train 11 I rode on a few days ago!

The 2009 stock give off a lot of heat - you can feel it when you stand next to one on a platform, This is making the line hotter, and will get even worse as more of them are introduced.

I'm not being funny but the 92ts pumps out heat like there is no tomorrow. I was standing at Leyton the other week as the train came in, once it stopped I could feel lots of heat rising from below...and Leyton is of course overground!!

7 2009 stock were in service in today's evening peak: set numbers 234, 235, 236, 237, 240, 271 and 272. However, there was a minor hold up due to a defective train (not a 2009 stock!), so there were a couple of delays and reforming of services, meaning that the 2009 stock ended up also working on 215, 217 and 220 at the expense of 235, 236 and 272, which became 1967 stock. A driver waiting to pick up 215 at Seven Sisters eastbound got a surprise when he saw it was a 2009 stock - "It's my first time since training!", he said to another driver.
I've noticed that most of the time 2009 stock have two people in the cab - who is the second person?

Obviously I don't work on the Vic, but I reckon the second person is an instructor operator, there to offer guidance to a driver operating an 09ts for the first time - it may have been quite a while between training and actually getting a proper go...

I had an unlucky encounter with train 5 today at Brixton, it was a total scorcher compared to train 11 I rode on a few days ago! Train 11 is getting warmer - trust me on that one! Caught it with a couple of friends on Sunday at Green Park around 1312ish. Although it is still cooler than the old stock. One thing I did notice mind you is that older stock was definitely having a lot of intervention to bring it to a stand over the last few days.

Lot of manual braking?
Only 2 of the 09ts cars are trailers so the extra heat may come from the extra motors! Of course the 92ts is all motored.

The 67 stock often need a touch of the manual brake to get them to stop in the correct place - not a new thing either!

I've been on the Vic many times and I've only heard a tap on the emergency once - quite an odd sound as the air comes rushing out The 09s feel rather warm but far better than the 67's IMO.

I've travelled on an 09 a couple of times now even though I don't use the Vic very often. I was out with a friend a couple of weeks ago and we got on one (by pure chance), I got all excited about it and she laughed at me.........

Regenerative breaking systems in general (I don't know specifically about on the Vic) have the potential to overload the electrical supply systems when they feed electricity into it rather than taking it out, and often they have to be upgraded before regenerative breaking is used. It is conceivable therefore that the regenerative breaking is not switched on as doing so would damage the electrical systems of the 1967 stocks which were not designed with it in mind, and which are not worth modifying to cope. I don't know whether the regenerative breaking on the 09s is enabled yet or not, or if it isn't if this is the reason why. If it isn't enabled though, this being the reason would make sense.

Ah so we have to wait until the rollout is complete before we start seeing material difference to the temperatures on the Victoria line.

If my guess above (and I stress again it is just that) is correct, then that would seem to be a logical conclusion

Are the 09's supposed to be noisy or is it simply because they are new? While waiting on the NB FCC platform at Highbury & Islington yesterday, a NB 09 came in on the other side. The noise it made starting off was considerably more than the noise made by the older stock

These trains, like most, are powered directly from the lines. Would it perhaps be better to run off batteries, with the electric lines constantly supplying charge to the batteries? That way, the regenerative braking need not stress the system, merely charge the battery.

That way, the regenerative braking need not stress the system, merely charge the battery. Would need a shed load of heavy batteries to make that worthwhile but I see where you are coming from. It's so wastefull to burn of the electricty with resistors and make the train even hotter while going about it.

If you're talking about the traction motor sounds they certainly are louder than the old DC motors on the 67s. That's just the nature of inverter-based traction packages, they make unique sounds - although the 09 traction package is rather loud for IGBT inverters!

It could have been my very frist trip on an 09 - but my old 313 was just then itself pulling into my platform.

09s aren't that hard to find now. Wait a few trains and it's easy, there are plenty in service.

I'd be surprised if the majority of commuters get more than 2 Vic-line trains a day, 5 days a week and 1 in 5 trains being an 09 still gives a 4 in 5 chance of each journey being a 1967 (assuming that the 09s always provide exactly 1 fifth of the service). My maths isn't good enough to work out what the probability of all teh trains you get being 67s though!

My maths isn't good enough to work out what the probability of all teh trains you get being 67s though! Assuming 10 journeys per week, there is a 11% chance that every train caught will be a 67 stock. Four fifths is 0.8, and you raise that to the power of 10. Therefore, there is an 89% cnance that at least one of the journeys that week will be an 09 stock. Lesson over! ;D EDIT: But as the 09 stock tend to run on the same set numbers, people who leave work at the same time each day may stand a significantly greater chance, if that time conincides with an 09 stock path. But with a train just over every 2 minutes, you'd have to be pretty accurate, and then assume that the service was running dead on time. EDIT 2: When the 09 stock operates two fifths of the service, the chance of getting a 67 stock on all ten journeys decreases to 0.6%.
