Warmest Underground Line

[Mutant Lemming]

I remember being told that the highest recorded temperature below ground on the underground was at Paddington on the Bakerloo. Does anyone know if this is actually true?

I'm not so sure, I've been in 40C heat at Covent Garden during the peak of summer (mid July).

The new 09 stock on the Victoria line pump out a lot of heat due to Air Conditioning, but I think they may have solved that.
I remember how Oxford Circus used to be very warm on the platforms before they began experimenting with pumping cool water along the outside of the tunnel walls (me thinks??)

Found this on BBC from 2009, says the Central and Bakerloo recorded highest temperatures.

I always find the Central Line very hot and stuffy, even in the winter, although this doesn't seem to be quite as bad since the 1992 stock was refurbished.

The 09 Stock doesn't have air conditioning. I thought the heat coming off those trains was something to do with the brakes, something that has been (at least partially) resolved through regen. braking.

Must be confused with the 'S' stock. Anyways I've always had a warm and uncomfortable experience on the 09 Vicky stock!

I remember seeing a map on the hottest parts and if I recall it was the bakerloo between Paddington and Marylebone/Baker Street.

Was this the one?

I wouldn't really describe it as a refurbishment by LUL standards. More of a refresh.

Not sure to be honest, although that BBC news article states Bakerloo stations reaching 32C in July

Remember when i was visiting London in 2006, time of the heatwave in mid to end of July that year, walked into the ticket hall at Victoria 10pm & immediately felt the humidity, by the time i got to the Circle line platform i was drenched in sweat.

I've wondered why it's so warm on London Underground stations below ground, when my local Merseyrail Underground stations the air is quite cold when a train is approaching the station?

 

[Mutant Lemming]

The reason that people would say the Bakerloo was hottest was due to it being a single ended route with no exit. The Northern line though longer tunnels had an exit at each end while the Victoria Line was supposed to have better ventilation. On reflection though the Bakerloo does have an exit at the South end up to London Road depot but I do recall the Elephant & Castle being stifling in the Summer months - especially down the sidings where they had a mosquito problem.

Number of people and density of train service maybe or possibly the rising water table (one could actually hear fast flowing water at some locations) has a cooling effect.

May also be due to the fact that the Merseyrail is more Sub-Surface as opposed to Deep Level Tube Lines in Discussion.

From extensive personal experience of Tube journeys in Zone 1 (during periods of almost every conceivable type of British weather outside, bar tornados*), the hottest bits are Green Park-Oxford Circus on the Victoria Line, around Chancery Lane and Liverpool Street on the Central Line and just South of Regents Park on the Bakerloo Line. I'm not exactly sure which are the "stuffiest" bits, as it seems to vary (IMO).

*Yes, I did just mention those.

 

[Daniel]

Hottest temperatures are on the Bakerloo line.

 

[trivran]

Chancery Lane, hot? Liverpool Street and Bethnal Green yes, but I've never found Chancery Lane to be a place where I can sweat from sitting on the platform.

Victoria/Bakerloo

The Victoria line is particularly bad, especially with the 2009 Stock's wonderful design feature of blowing hot air straight into the carriages...

Apart from that I've always found the Northern line to be the worst for heat.

I seem to remember reading a few years ago that LUL had fitted out a special cooling train to run through the tunnels and try and cool them down. Am I misremembering this and if not does it still exist?

Unfortunately you are mistaken and such a train does not exist.

 

[Aictos]

Any non air conditioned train so at the moment that restricts it to any route not using S Stock

 

[gazzak]

As an apprentice on the tube I worked in a lot of tunnels during non service hours and the Northern line was always the warmest by far, (at any time of year).

Bakerloo and Victoria were terrible last July, I remember taking the bus, which took forever, just to avoid using them they were that bad, I was drinking so much water it was incredible, must have been at least 40C under there, there were announcements at every station advising people to make sure they had water with them!

Central line is always bad at weekends too, although I figure that's normally because it's jammed with the circle and district always closed.

For platform (not in-carriage) temperature: Edgware Road (Bakerloo).
