Not sure how many readers here take the 'New Scientist'' journal but you might be interested in an article by Justin Mullins in the Aug 6th issue page 38. about the problems around keeping the underground,trains and passengers cool.
He went around the Victoria Line with one of the LUL engineers Kevin Payne.
There is an interesting map showing the system and average temps taken on 28/7/2008 between 16.00 and 19.00.
Some stations like Oxford Circus hit 32c .Not surprising.

Thats actually quite 'average' for the tube! its not unknown for temperatures to get as high as 42c, if not even more in places!

Get the Jubilee Line. You won't be complaining about heat, even in crush load peaks. That or find yourself an S stock!

The 09ts do seem to have the heater on mind..

Then there's the endless fans and air con equipment to cool Connect radio equipment, signalling equipment, rooms with people in and what not!

There's a video knocking around on youtube with someone recording the temperature as an 09 train pulled into a station on the Victoria - I'll have a look a bit later for that.

The Jubilee line is quite cool even in the peak like CharlieJ said. The Central line is probally the hottest line and the victoria line.

I try and avoid all deep level tube travel wherever practical. I don't mind tubes above ground obviously but anywhere else I'd rather use the SSL and/or the Overground and take a walk at the end. Sweaty, farting sardines all around me ain't my idea of fun, however fast they make it.

I prefer the Deep Level tubes. Overground makes me sick and SSL apart from the Met north of Baker Street feels painfully slow.

Why is the Piccadilly so cool according to the diagram?

I have to say the last couple of times I've used the Bakerloo line (1972 stock) it has been notably hot. Most uncomfortable. There's a video knocking around on youtube with someone recording the temperature as an 09 train pulled into a station on the Victoria - I'll have a look a bit later for that. I have a feeling you're referring to the video on the BBC news website which shows that the temperature recorded with a hand-held thermometer was 40 degrees centigrade. www.bbc.co.uk/news/uk-england-london-13946359 |

Bakerloo line trains are hot, even on the open section north of Queen's Park! Opening the car-end windows doesn't help much, either.

Yeah, ive never found the Piccadilly line hot at all, maybe its the slightly different ventilation to the 72ts?

With trains running the ventilation is quite good, however, it's a different story in Engineering Hours when the air becomes still and the temperature rises considerably in the tunnels until around 0400 when it falls rapidly. |

I think the deep-level tube lineas are hotter than thye were 25-30 years ago (for the reasons stated in some of the earlier posts). Agree (assuming you can remember back that far)?

Definitely. I used the Underground a lot in the late 70s and early 80s and I don't remember it having been as consistently hot as it is now.

RT, when you say temperatures drop at 4am, is this because traffic is starting up again? What effect would/have long term stoppages have/had on temperature?

^^No cold air is being pushed in by the movement of the trains i'd assume?
IMO something has to be done about the heat on the tube, even it winter I find it too hot.

RT, when you say temperatures drop at 4am, is this because traffic is starting up again? What effect would/have long term stoppages have/had on temperature? No this is because there are no trains generating heat within the system and the heat in the air is gradually dissipated. Of course this doesn't apply where work is in progress with lots of bodies present. We used to generate enough heat simply by working to maintain the temperature in the immediate area especially in places such as Knightsbridge, South Kensington, Elephant & Castle, Baker Street etc. I would agree that the tunnels were not as hot back in the 1970s and 1980s although Baker Street was quite hot back then but of course there were hundreds of us working there on stage 1 Jubilee which did tend to raise the temperature and the old Bakerloo tunnels were much dirtier then too which didn't help. |

As posted on the Vic thread districtdave.proboards.com/index.cgi?board=victoria&action=display&thread=16926&page=6the stations and trains are heated in Winter. For deep level stations and tunnels this is hardly useful as they are more than than not too warm. If the trains and tunnels weren't actively heated, I think the temperature would remain cooler throughout the year. But in addition, if you look at the schematics for Crossrail and the associated LU works, there are additional ventilation shafts to be bored at TCR and Bond Street which will directly benefit The Central. The improved passenger flows and entrances will result in people remaining underground for less time, reducing the heat generated and trapped under the ground. Hopefully with fewer people transferring from NR services at both Stratford and Liverpool St onto the Central, passenger loads may be reduced and therefore reduce the temp further. some schematics here www.skyscrapercity.com/showthread.php?t=871486&page=13 |
