More likely the other way around. FCC couldn't run the proverbial ****-up in a brewery without the beer being delayed going by what they've done to Thameslink and WAGN. The new ELLX trains will travel on the slow lines between Croydon and New Cross Gate, and I believe they will _not_ need to cross the path of the fast lines whatsoever - and it is the fast lines which the FCC Thameslink trains take. That still leaves the possibility for the ELLX to bog up Southern's services on the slow lines of course. |

I think you actually meant to write "more power hungry" rather than more powerful. Efficiency doesn't seem to have been in the brief when they were designed. B2003 More powerful might just equate to more power hungry as well, though I've no idea whether the Electrostars are more powerful than the Networkers (and to be fair to Mr Salter, he didn't mention efficiency - though I agree with your underlying point that it's important). Plus AIUI the new ELLX will be more intensively worked (i.e. more trains) than the 90's power upgrade allows for, which might suggest that it wasn't done with enough foresight. |

As a regular user of the former WAGN part of FCC's franchise my experience since last April is that you are talking through your rear orifice. Oh look , its you again. Well as a regular user of Thameslink I can say categorically that roughly 80% of the southbound trains in the morning rush hour are late. Some by more than 15 minutes. This was not the case when the thameslink company ran it. And my last experience of taking the WAGN service from finsbury park 2 months back was not a pleasent one - overcrowded trains and late.

B2003 Yup, we in Cambridge were certainly better off with WAGN than with First (and I use FGW too, so I can see the signs of the slippery slope). |

"Paul Corfield" wrote in message ... AIUI the ELL is having its power supply, current rails and signalling all changed to match National Rail standards. On the face of it, there seems to be little reason why a power supply upgrade can't allow for the 4th rail to remain while LU stock remains in use on third rail power, like Putney-Wimbledon, Gunnersbury-Richmond. Isn't the spec for the third rail position same as NR tracks, and isn't the track new anyway, or is it only in the Thames tunnel? The physical integration issue with other lines is different - the northern section will be linked in on a section that is closed anyway so no impact there. At the southern end I understand that a flyover is to be constructed and I imagine there will not be a huge issue with linking that in - a longish weekend possession could deal with that. As you say, on the southern end it seems the major infrastructure works are only on the New Cross Gate branch - so is a temporary Whitechapel - New Cross only service really out of the question? The bigger issues concern testing all of the signalling and control systems and the new rolling stock and training the drivers on the larger network. I don't think the signalling in itself could take anything like 2 and a half years though. The signalling complexity must compare with the current NR resignalling scheme in the Portsmouth area, in terms of numbers of stations, junctions, distances, and interfaces with other signalling areas. This is requiring major closures for about 6 weeks if all goes to plan, although preparatory work has obviously been done over normal overnight and some weekend possessions. Given the ability of the expanded ELL to spread delays all over north and south London I imagine a lot of time and effort (probably 6 months if not longer) is going to be spent to try to ensure the new line is reliable from day one. If not then TfL will be paying out a lot of cash to FCC and Southern for delays to services between Central London and Croydon. Agree with this - one of the pitfalls of the line becoming so integrated with the NR 'networks', given that ELL connects effectively seperate areas of the NR system, to the north and south. Paul S |
