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? -- Roland Perry |

I believe they will be using the two service tunnels each side of the main road tunnels. -- Graeme Wall This address is not read, substitute trains for rail.

Mar 2006, Graeme Wall remarked: I believe they will be using the two service tunnels each side of the main road tunnels. 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). -- Roland Perry |

writes 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? 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. -- Paul Terry |

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? AFAIK yes those are they. I believe they were originally pedestrian tunnels when built. There have been various suggestions of what they could be used for over the years. 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). I wonder if they are going to try to move the drop-off point out of the central area? Would certainly help reduce the amount of traffic there. -- Graeme Wall This address is not read, substitute trains for rail. Transport Miscellany at http://www.greywall.demon.co.uk/rail/index.html |

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 ? Cheerz, Baz |

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). -- Dave Arquati Imperial College, SW7 www.alwaystouchout.com - Transport projects in London |

Having read all the posts here I have to say I have two issues with the proposed use of the side tunnels. The first is width. The tunnels, as currently configured have a lane wide enough for a car/taxi and not much else plus a narrow foortpath. The pictures suggest sufficient width for two PRTs. Now, I can't find a reference to how many people each PRT will carry abreast but unless they only carry one (so maybe 2 in total) I would seriously question whether you'll get 2 into the width available. Secondly, where is the second level? I have been visiting Heathrow on a regular basis since those tunnels opened. The side bores that are currently used as taxi tunnels were originally for bicycles and pedestrians. I don't remember ever seeing a second level. If they do exist I have to assume they are for "services" and full of things like cables and pipes. Now, none of that makes the proposals unworkable. Why do you even need 2, much less 4 tracks? But it does make me wonder a bit. |
