Using 39 trains in total. They ordered 47 2009 stocks to run a 43 train service. Will there be a further upgrade? There is a timetable change being rumored for the early part of next year and another one towards the end of the year/early 2016. I assume the target of 36 TPH will be brought in with one of them. |

Thanks. 36 tph will be interesting! |

The approach speed to Oxford Circus northbound seems to have been restored to the previous level. I only tried it in the off peak though.

In the appendix of TfL's new transport 2050 document it states that the Victoria Line is planned to reach 36 tph peak with all trains terminating at Walthamstow by 2016.

In the appendix of TfL's new transport 2050 document it states that the Victoria Line is planned to reach 36 tph peak with all trains terminating at Walthamstow by 2016. 36 TPH through the central area has always been the target since the 09 stock was introduced, as things stand at the moment, 36 TPH to Walthamstow is a non starter. WTT 36 introduced T/Op's stepping back at Walthamstow during the peak hours which seems to be working, there have been a few hiccups which had they have happend with 36 TPH would have shutdown the line! |

Is there a technical reason why Walthamstow would be less capable for turn-arounds at 36 TPH than Brixton?

At present, the crossover has quite a hefty speed restriction on it, which has been in place for some years. For a start this would affect the platform re-occupation times. Also Walthamstow has never previously had stepback equipment fitted, although this has now changed. |

I see. So nothing that can't be fixed if the money is there? Does this mean we can expect many weekend blockades (like last weekend?) while the crossover and equipment are brought up to scratch?

There's no plans at present to replace the crossover at Walthamstow. The stepback equipment is already in place. |

Does this mean that the 2050 doc is incorrect to state that all trains will run through to Walthamstow? Or is it an aspiration for money for an additional upgrade? |

"Stepback equipment"? A platform and eyes to see the train number on the next train you're working surely?  Or is there something I'm missing? |

You need a rear cab clear plunger (it may go by other names) to let the T/Op who's just taken over the train at the front know that the T/Op who brought the train in is out of the back and isn't still there, about to be taken - against their will - to Blackhorse Road, which'd screw everything up  Only when the plunger has been pressed should the train depart (obviously assuming it has clear signals, a pilot light and everything else). |

...with all trains terminating at Walthamstow by 2016. I imagine that Seven Sisters to Walthamstow Central is probably quite well used and I daresay there's plenty of demand to make it worthwhile sending all trains to Walthamstow. But, if only for service recovery, surely there must be a good case for making tweaking the layout at Seven Sisters to make it easier to reverse there. I always thought the layout at Seven Sisters was obtuse - surely a simple crossover south of the station, connecting platform 4 with the southbound from platform 5 would make life much easier and you wouldn't have to tip out. I don't wanna hijack this thread with a RIPAS topic - but since we're doing service constraints on the Vic and their potential alleviation, I just wanted to ask: does anyone know why this wasn't done to begin with/hasn't been done already? |

That simple crossover south of the station would take a hell of a lot of work to install. The easiest place to install a crossover in that area south of Seven Sisters I imagine would be Netherton Road fan shaft, but that's far to far to the south of Seven Sisters. |

Hmmm, you are right of course. I suppose it would have been better if it had been designed like that in the first place, but no use complaining about that now. |

A 'rear cab clear' plunger and visual on each platform, and also most importantly an office for drivers and managers. The office is constructed in what was the former IMR. |

Yes all of the platforms with the restricted approaches now seem to be faster, if not full speed. Can anyone give a full explanation of why these speed restrictions were necessary, and what has now allowed them to be removed? I believe the locations were Oxford Circus and Victoria s/b, and Victoria, Green Park and Oxford Circus n/b. |
