18 pods, 25mph, two miles of track... I make that 12 times round the
track per hour per pod, or 3 per minute; perhaps well able to achieve
the 1 minute waiting time.

A bigger puzzle is how they will get to T1 from the far side of the
runways where the "perimeter" car park presumably is - will it be taking
over one of the existing road tunnels?

This being why I was asking if a map or diagram is known of i.e.
exactly where is being connected to where.

I thought the article said it would use one of the service tunnels alongside
the main road access tunnel. I should have thought a few more buses would
have cost far less and been much more flexible !! Perhaps when Ken gets rid
of the bendybuses they could be used for this job ?

I believe they will be using the two service tunnels each side of the main
road tunnels.

Buses don't quite have the near-on-demand characteristics of Ultra,
without running an awful lot of them! In theory, Ultra should also be
cheaper to operate.

Personally, I think it's an excellent testing ground for the technology
(rather than plonking them into the centre of Cardiff before they have
been tried out on a larger operation than the test site).

Sorry, yes, it does say that in the article :-(

Are those the tunnels that are currently used by taxis, and have a
"loading gauge" hanging over the entrance? Or are the service tunnels in
addition to those? The area between the airport end of the tunnels and
T1 is currently somewhat full of roads and car parks, it will be
interesting to see how they weave this pod-track through it all and up
to the terminal building (currently the frontage is occupied by the car
drop-off zone).

It looks like it. A proposed route is shown on page 3 of ...

http://www.atsltd.co.uk/media/casest...se_studies.pdf

Page 4 shows (somewhat surprisingly) that it is possible to fit four
people-mover tracks inside one service tunnel - although it doesn't
explain what will be done with the displaced taxi traffic! I wonder if
there might be room to retain a taxi-way below the upper pair of tracks?

The maps on pages 59-62 of the Heathrow Masterplan (big download) ...

http://www.heathrowairport.com/asset...MasterPlan.pdf

show more extended systems, with different routes, to take account of
the third runway proposal.

I'm astonished that there's so much room! Must have a better look next
time I'm there. All I remember is the loading gauge and a general
feeling of claustrophobia when approaching even in a car, that made me
choose the main tunnel instead.

although it doesn't explain what will be done with the displaced taxi
traffic!

It's always a bit sad when a scheme mentions the benefits (fewer buses)
and omits the drawbacks (more taxis in the central bores). Makes you
wonder what else they "forgot" to mention...

Bicycles ? Don't know if they still are, but the taxi tunnels used to
be signposted for cycles too.
