Why is the Victoria line so hot these days?
I've noticed the victoria line seems to be much warmer than the other
lines these days (or maybe it always has been but I've not noticed). Is this because the trains are more frequent , or they use up more energy on ATO , or the tunnel ventilation isn't so good , or is there some other reason? B2003 |

Victoria line is completely underground - it does not have a natural
source of fresh air, like most other lines. |

Perhaps its because Victoria-line trains remain entirely underground while in service. -- Paul Terry |

B2003 Of the deep tube lines, the Central, Northern and Jubilee are cooler as they use more modern traction and braking technology that doesn't create so much heat. The Vic should be cooler when it gets new trains in 2009. |

Always has been hotter (well as long as i've been travelling on it). I've asked this before on here, the answer i got was that it's to do with the fact that the Vic line is completely underground and so the trains don't have any fresh air to cool off in except when they go to the depot. It's really noticable at Highbury & Islington where the FCC platforms are like a fridge in comparison |

I'm not convinced its because its completely underground. After all the northern line is underground all the way from mordon to east finchley and golders green. Quite long enough for the tunnels to build up huge amounts of heat but its not as hot as the victoria line , which does have the surface exit to the depot near seven sisters anyway. B2003 |
