Don't forget the plan is unless it's been changed for the pic to run to Ealing Broadway so the district won't be a issues except for Ealing common depot trains but I assume they would all be off peak

I wonder how will the stopping positions change when the new trains arrive, and whether extensive platform extension works need to be done. I also wonder if because of longer trains some curves need to be smoothened out since they are relatively sharp already on the 73 stock.

I also wonder if because of longer trains some curves need to be smoothened out since they are relatively sharp already on the 73 stock. The trains can't be significantly longer than the 73 stock already in use or they won't fit into shorter platforms such as Holloway Road or Caledonian Road. As drivers when we still had guards, trains had to stop on the stopping diamond usually located just inside the headwall tunnel mouth or else the guard would still be inside the tunnel at the rear of the train. Most of the original stopping diamonds are still in place. Using a seven car train won't give any problems going around South Ken bends, unlike the 73 stock that has six cars. |

The trains will be approximately 113m long; roughly the same as the old 1959 tube stock that used to run on the line |

I also wonder if because of longer trains some curves need to be smoothened out since they are relatively sharp already on the 73 stock. The new train is longer, about 113m (up from 108m for 73TS), but with individual shells that are shorter and proper attention to gauge compliance in their design, curves don't need to be eased. I understand there are no physical platform extensions but many platform end barriers and other 'furniture' will be moved. |

With selective door opening there shouldn’t be too many problems fitting the new trains in. If it can be done at Paddington-NottingHill Gate it can be done anywhere! (Dwell times permitting!)

I understood the plan to be to adjust the platform end barriers so all doors are openable. SDO is much the non-preferred way - at least until time or cost overcome everything else! |

The current plan is only 27tph under current signalling. It also assumed District resignalling to Wimbledon and Richmond to take diverted trains, which has currently been abandoned! |

A number of posts relating to Selective Door Opening were more pertinent to the Sub Surface lines, and have been moved here.

Don't forget the plan is unless it's been changed for the pic to run to Ealing Broadway so the district won't be a issues except for Ealing common depot trains but I assume they would all be off peak I still do not understand how that will be benefical. If there are 3 extra trains an hour then to provide a train every 10 minutes to Ealing Broadway (ie: 6 trains an hour) is going to require a reduction in service to somewhere else! |

It doesn't happen until current 24tph become 30tph with resignalling, leaves +6tph for Ealing. Interim 27tph with current signalling is not enough as you say. |

What happens to Chiswick Park with Piccs providing the EBY service? And indeed do Turnham Green to Ravenscort Park get a reduced service? Or are some Piccs going to run on the local lines?

No change until Picc resignalling - 10 years? Half current District to Ealing diverted to Richmond, and half to Wimbledon, but resignalling of those branches is currently suspended! All Picc stop at Turnham Green all day - long promised. For a long while Chiswick Park was to get new platforms on the Richmond branch from the current ticket hall. More recently suggested Picc will connect to local lines for current Chiswick Park platforms for Ealing and Rayners Lane trains only. The District resignalling is to eliminate Picc from the local lines from Hammersmith, and prevent District on the fast lines. A long way to go with all this. The new Picc trains are just a start. |

Yes, rather as I thought. So it's a long time before those changes, if indeed ever. Comments about a postulated 5th platform at Acton Town for level access are still relevant with all that idea's pros and cons. I doubt that would ever happen either  |

I always thought it a strange arrangement especially with the District still needing to stable at Ealing but not serving the area in Passenger service.
I’m not sure how serving three branches is going to help the Piccadilly but at one stage there was a plan for the District to go to Rayners Lane so it’s swings and roundabouts I guess!

Ealing reversers apparently cuts the number of new trains to be bought, costing £16m each, instead of running on to Heathrow, but they could turn at Northfields as currently. Also allows a boost to other District branches, especially Wimbledon where there is a lot of unmet demand.

but at one stage there was a plan for the District to go to Rayners Lane The District did go to Rayners Lane, and indeed Uxbridge, between 1910 and 1933 |

I wonder if it would be probable for the H&C to go Upminster, the District to Uxbridge thus sharing with the Met, while the Piccadilly will go to Ealing Broadway and Heathrow which looks like a good balance. Only issue is whether it will cause overcrowding from Elm Park to Barking.

That won't improve the trains to go to Richmond which is the whole idea of pic line going to Ealing Broadway if anything would make it worse |

So what are they doing on the Piccadilly over the Christmas and New Year gap? This announcement does not even bother to tell people why they are closing chunks of the line. tfl.gov.uk/tube-dlr-overground/status/?Input=&lineIds=&dateTypeSelect=Future%20date&direction=&startDate=2020-12-29T00%3a00%3a00&endDate=2020-12-29T23%3a59%3a59#line-lul-piccadillyNormally I would understand that this period is the sensible time to carry out track renewals etc, however this year it seems exactly the wrong time to do these works because the Government has effectively said the COVID movement restrictions will be briefly lifted and people will finally be free to travel between Christmas Eve and New Year. There have been loads of posts suggesting the tube and TFL rail services are currently quite lightly loaded - which to be honest is what you might expect with the Government stressing that people stay home and avoid non essential travel. I wonder if the right time to be closing lines is actually right now before the holidays - as come the point when people are allowed to travel in the Christmas-New Year gap, lines could be suddenly overwhelmed with passengers wanting to visit relatives around the country/capital - especially those they have been prevented from visiting for many months. I really hope all those planned rail replacement buses will have lots of extra capacity with many seats blocked off to ensure social distancing. |

Probably a bit too late to actually close now because they require planning

There have been loads of posts suggesting the tube and TFL rail services are currently quite lightly loaded - which to be honest is what you might expect with the Government stressing that people stay home and avoid non essential travel. Engineering work such as the points renewal at Acton Town are planned months, if not years ahead of time, and are usually part of larger projects. Cancelling such major work would have seriously detrimental effects to the railway and other projects that come later. It would also cost LuL millions. |

That's higher than I thought; I must pay more attention when I'm in meetings and the Project Manager discusses finance!

Are there any signalling alterations as part of the Xmas Acton works? WL116B being removed? I should probably read the traffic circular properly to find out of course...
