Cooling the Tube. [Mar. 12th, 2008|11:30 am]
[Tags|, ]

Hello. I went to a talk last night about cooling the London Underground. It was interesting. I took notes, and have written them up. This isn't in the exact order the talk was in; I moved some stuff around to make more sense (the speaker mentioned that his slides weren't in the optimal order, so his talk wouldn't be either).

The talk was at the Building Centre in Bloomsbury, and the speaker was the director of TfL's Cooling The Tube programme, Kevin Payne.

Rather long.Collapse )

I have already spent way too much time on this, but I may come back later and add some supplementary links/explanations (or perhaps the other Tube obsessives and/or the engineers on my friends list will do it for me). Also, I took some photos of the Building Centre's scale model of Central London, but I haven't had a chance to sort them out yet. Edit: here they are.

Geek Squee indeed! I had not been aware of the drying-out effect around the tunnels - and I find it surprising, as where would the water go, faster than it could be replaced by capillary action from surrounding soil?

I had always assumed that the increasing problems were due to decreasing train speeds and service frequency; less forced air movement and, within each train, more people crowded in and heating up the air.

Utterly fascinating. Thanks!

How did you find out about this talk?

I think it was because Ewan added the Building Centre to RGL so I went and had a poke around their site. As for where Ewan found out about the Building Centre, I'm not sure. It's been there for a couple of years.

Have I missed something

How about turning the heating on the trains off? There are very often vents under the seats that pump hot air into to the carriage. I've never been too cold on the tube, am almost always too hot.

The last thing you need when it's cold outside is to enter the train with a huuuge coat on and be met with a wall of heat. At least vent the hot air outside if it's a product of the engines!!

Interesting article though, thanks!

Re: Have I missed something

Glad you enjoyed the writeup. Which lines/units have heating?
