In article cbdb0206-4847-455b-af10-3e344d0db8d5 @o30g2000vbc.googlegroups.com, says... Unfortunately even if they extend crossrail to Reading it still can't replace all the stopping services because there are 2 stopping services an hour from Oxford which call at many of the intermediate stations. So then you would either have to electrify the line to Oxford (ooh, look a flying pig) or more realistically terminate slow Oxford services at Reading and inconvenience passengers from intermediate stations between Reading and Oxford. Of course there is the option of running the Oxford slow services under the wires on the slows but this would take up valuable crossrail paths and of course result in more diesels under wires which is a waste of fuel. Or they could do as the Bedwyn services do and stop until Reading and then run fast into Paddington. This assumes that capacity can be found on the main lines for 90mph services between the 125mph service. Duncan But this still wouldn't be an ideal outcome, Oxford already has fast services calling at Reading and Slough only, and passengers for intermediate stations would need to change at Reading, so you might as well terminate the service at Reading, but this would reduce the tph from Oxford to Paddington from 4 to 2. Incidently the current Oxford fast services are commonly 165s or 166s anyway so there are already 2 paths an hour for 90mph stock, whether there is any room for more than that is debateable. |

We're looking 8 years ahead, as Crossrail won't open before 2017. While Crossrail trains won't convey passengers from London beyond Maidenhead, or perhaps Twyford, it should be worth running them through to Reading, to connect from intermediate stations into trains running further west, and to save having to run dmus on the Relief Lines. Intermediate stations Tilehurst to Cholsey, also Appleford to Radley, would lose their off-peak through trains to Paddington, though this wouldn't be much of a loss, as passengers mostly change at Reading on to a fast. In the peaks there could well be trains from Oxford or Didcot which stop to Reading, then run fast to Paddington (and these should be 125 mph stock - IEP anyone? Crossrail trains shouldn't be all stations west of Paddington. It probably wouldn't be too much of a loss if there were no through trains to Bourne End or Henley - many passengers would be able to get a through train from a central or east London Crossrail station to Maidenhead or Twyford, so they would be saved the Paddington interchange at the expense of a change at Maidenhead or Twyford.

Peter The main losers would be stations between Oxford and Reading which would lose out on direct London services and also no direct services to intermediate stations, which is a shame, but it is probably easier for everyone else if they just change at Reading. And yes, it would only be a change at Twyford or Maidenhead instead of a change at Paddington, and changing at Twyford is a lot simpler than a change at Paddington. |

No it wouldn't - there are already only 2tph from Oxford to Paddington in any meaningful sense, as unless you're a great lover of spending time on 16x-es instead of at your destination, waiting for the next fast train is always the best option.[*] Splitting the slow trains into a 2tph Oxford-Reading stopping shuttle and a 2tph Reading-London extra Crossrail would only be a significant inconvenience for passengers from stations west of Reading seeking intermediate stations between Reading and Paddington (as if you want to go from Goring to Paddington, you'll change onto a fast train at Reading anyway). [*] well, actually getting the next fast train to Reading, whether it's XC or FGW, and then the next fast train to Paddington, whether that involves changing or not, is the fastest option, but it only saves you a few minutes compared with waiting for the direct fasts. -- John Band john at johnband dot org www.johnband.org |

Well, yes it's not a major inconvenience for passengers travelling to Paddington, and since most passengers are presumeably travelling to Paddington they won't be affected by the change because they will either change at Reading as they usually do, or simply catch a fast train from Oxford instead. It's only a more significant inconvenience for passengers travelling from Twyford to Tilehurst, for example, who would have a twenty minute journey replaced with 2 10 minute journeys seperated by an inconvenient change at Reading. |

The AirTrack scheme clearly envisages HConn/Crossrail coming into the H5 box and extending west out of it. Proof please - just where does it state or heavily hint this is the case? I understood they will be using separate platforms at T5, with no connections. What happens to HEx and links to H123 then would be influenced by the commercial imperitives of the day. Possibly - but currently BAA have a long contract with the DfT, and by extension, NR, to run HEx services to HCen & T5. Something BAA won't give up unless *they* want to do so. |

I understood they will be using separate platforms at T5, with no connections. Some of the comments from online dox: A. http://www.heathrowairport.com/asset...w_Brochure.pdf 1) "Other benefits of the new, environmentally friendly services include: improved rail services in areas to the west of London and in the Thames Valley improved public transport access for the local community to Heathrow Airport and its associated transport connections into London including Heathrow Express, Heathrow Connect and London Underground services ... " 2) "BAA also has an aspiration to extend the Heathrow Express service to Staines. This would mean an additional two trains per hour in each direction. ... " 3) "The purpose of this addendum to the initial public consultation brochure is to clarify how Heathrow Airtrack trains could be powered and the options that are being considered. Overhead Line or Third Rail Electrification? At the Heathrow Terminal 5 station it is not feasible, for technical reasons, to operate Heathrow Airtrack trains with third rail electrification. Therefore trains in the Terminal 5 station and tunnels will be powered using overhead line electrification (OHLE). OHLE involves a system of supports to hold electric cables some 4-5 metres above the tracks. This system is currently used by Heathrow Express trains operating between London Paddington and Heathrow Airport. As the existing rail network uses third rail electrification it will be necessary to change from third rail to OHLE at some point between the Heathrow Terminal 5 station and the rail network in Staines. The Options Three options for making the change from OHLE to third rail electrification are currently being considered: 1 change over as close to the tunnel entrance as possible, while trains are moving. It is possible that in this option the overhead lines may not need to extend onto the SSSI at Staines Moor 2 change over from OHLE to third rail electrification at the new Staines High Street station, while trains are stationary 3 run OHLE all the way to the existing Staines station. This option would allow Heathrow Express services, which currently use OHLE, to operate to the existing Staines station and is favoured by BAA for that reason In addition, the adaptation of the current rolling stock used by Heathrow Express is being considered. If it is possible to adapt the trains, the need to extend OHLE to the existing Staines station could be avoided. One of the benefits of extending the Heathrow Express service to the existing Staines station is that there would be a direct service from Staines to London Paddington. Passengers using other services from London Waterloo would also benefit from a more frequent service to Heathrow Airport, as they would be able to interchange at Staines station and board a Heathrow Express train. ...

This means that Crossrail would only run to Heathrow Central and Terminal 4 - not to Terminal 5. Passengers would be able to transfer at Heathrow Central to the Heathrow Express for free connections to T5.
