Interesting story in the media about temperatures on public transport on
Wednesday 'the hottest day (so far)'. It appears the tube is actually cooler
than mainline trains (except those lovely C2C trains) or the top of a
double-decker bus, which was hottest.

Perhaps people should be complaining more about getting air-conditioning for
buses, where the extra space could be found, rather than moaning about how
hot the tube is?

Those C2C trains really are great. Until recently I used them every
day, and it was wonderful to step out of an uncomfortably hot day and
into a nice cool, shady train.

I can definitely imagine that the top of a double-decker bus is the
hottest. I was in one on tuesday and I could hardly breathe. I must say
it wasn't helped at all when some idiot sprayed some deodorant around
on the bus.

My complaint about most modern double deck buses is not so much lack of
air conditioning, but larger windows with very little ventilation.
Effectively they are greenhouses on wheels...

On the subject of the tube, the "In this hot weather" posters mention
that "long term solutions are being looked in to. I know the engineers
all seem to respond with the usual "Oh no, we can't possible do that"
statement as soon as the subject of air conditioning on the tube is
uttered, but perhaps LUL can up date us on what these "long term
solutions" exactly are.

There were quiet a few stories regarding this in the press during the
last hot period we had this summer.

Anyway it seems daft. Air cooling the tube (trains and all) doesn't
need "inventing", it needs "paying for".

Oh well, it was taken from a post a few weeks ago and was working then.

Agreed. I've always wondered why - apart from cheapo bus companies -
they don't have openers fitted to all windows...

A return to the idea of having opening front windows on the top deck
would also be good - even if they're hoppers rather than sliding
windows in order to avoid anything flying in.

The tube has 2 issues when it come to air con.

1. The stations

2. The trains

Many of the stations are deep underground and you have to disperse the
heat and moisture somewhere. That could mean running literally miles of
pipes from the a/c units to street level or the nearest vent. Large
volumes of air being forced through the tunnels by the trains makes this
even more difficult as the air shifts around a lot. My solution would be
to put a large number of moderate size ac units above head height on the
platforms and have them running 24/7 in this hot weather. Whilst it
would not totally cool the platforms it would help. However there are a
number of drawbacks to this including increasing the fire spread due to
the air currents and the space these units would take up (not every
station would be suitable I expect). You then have to get rid of the
heat and moisture taken from the air and that means pipe work or drains
or vents and probably all 3!

On trains you have to site the units somewhere. On stock on the Picc and
Northern etc it may be difficult to fins the space - possibly easier on
the Met style stock where there is more space. However, as with the
stations what do you do with the heat and moisture to disperse it? On
open sections of track it wouldn't be a problem, in tunnels it would!

Tracking to busses, putting ac on a bus is relatively simple as they are
in the open for heat dispersion. Busses in both Hong Kong and Singapore
have ac units on the rear or the roof.

The Singapore Metro has air-conditioned trains and stations. Do you know how

stations for the station aircon to deal with?

I imagine they designed the system with ac in mind. When the underground
was built, it was never considered and may not have even existed then!

In New York City, the trains have ac and they dump the heat into the
tunnels which are well vented.
