Hi all Looking at the line closures for this weekend I notice that the Circle is completely suspended and the Met is suspended between Harrow and Aldgate. However the Hammersmith and City is running between Baker Street and Aldgate East. How is it possible for track works to take place on this part of the line is some trains are still running. Surely it would be possible to run the Met between Baker Street and Aldgate if the H&C is able to run? This is also the same for the District between Earls Court and High Street Ken and the H&C between Hammersmith and Royal Oak although here it could be argued that it is best to close the whole Circle Line instead of parts of it. There is probably a logical explanation, I just wondered what?  Cheers |

There is probably a logical explanation, I just wondered what? Cheers The Jubilee line is also suspended between West Hampstead and Stanmore. For reasons of probably both safety, and the fact that Metropolitan line services are probably unable to run to/from Neasden Depot, is why the Met has been suspended Aldgate ot Harrow on the Hill. The Circle line is suspended due to the fact that they can only get a limited number of trains into/out of Farringdon, and the decision makers feel (quite rightly IMHO) that running a reduced H & C service is more beneficial to passengers than a even less frequent three sided circle line service, as the circle line can be covered by the H & C on the north side (Baker Street to Aldgate East) and the District line from Tower Hill to Gloucester Road. If a three sided circle line service was to run, given the fact that the Wimbledon branch is also suspended beyond Putney Bridge, where would you then send the C stock once it arrived at Gloucester Road? The Hammersmith & City line is only operating Baker Street to Barking because of the Edgware Road works, which means they cannot run thorugh the Edgware Road area. These are merely guesses from past experience. |

Those are more or less spot-on guesses  The Met is suspended south of Harrow, as engineering work is focused on Neasden depot and the lines immediately adjacent to it - this is why the Jubilee Line is suspended. This means the service cannot operate south of Harrow, as no stock is able to be positioned for the whole weekend on the section south of Neasden depot. Engineering work is taking place in the Edgware Road area. The H&C is operating in 2 parts - Hammersmith-Royal Oak and Baker Street-Barking. The Circle then cannot operate as a circular service, and there is not room to reverse more than 1 service at Baker Street. Add to this the fact that Hammersmith depot cannot supply trains for the Circle (because of the closure). |

when all of the s stock has been introduced, would it be possible to run S7 stocks for met services on the central sections if there are suspensions stopping trains getting from Neasden?

Amost certainly not is the probable answer, as you would still have worker safety to think about on the work site at Neasden, and of course the Jubilee line would be suspended on such an occasion anyway. Because on that section of line the Jubilee and Met share the corridor, if one has work on it, the other must close for safety reasons. |

By then, the vast majority of the S7 fleet will operate out of the other depots, not Neasden. But of course as you were thinking of Baker St - Aldgate, the trains would almost certainly be described as Circles, since the Circle line covers the same segment. Or H&C if you are just considering Baker St - Liverpool St. It will generally be similar to current Engineering Works weekends. Whatever services are practicable to run still will be! |

I was thinking more of between Baker Street and Aldgate Absolutely no point in such a 'Met' service existing, as alluded to in previous point this is C&H/Circle territory The main point of through Met city services is i) a through service from destinations north of BAK to the city ii) another reversing location for Met services |

At this stage, to what extent are these weekend closures on the SSLs down to resignalling? I know it's early days but I can't seem to find much on the resignalling aspect (ha ha) of the SSL upgrade of late.

This weekend's closure of the Circle and part suspension of the H&C are due to re-signalling works in the Edgware Road area. Probably not the same re-signalling as you are referring to though. This weekend's works are connected with the S-stock project, for trains being manually driven. I don't believe anything is included as a side-line / later plug-in for automatic operation of trains.

Is the ATO project still in the design stage then?

Pretty much so, yes. Although from what I have heard there are the odd bits and pieces dotted about that are "ATC ready." In terms of full-on signalling and control kit, no there isn't anything installed as yet.
