There were a few logistical issues which meant that it wasn't as successful as people were hoping, but a number of oustanding tests were completed.

Apologies if I've missed it, but is there an issue causing platform 2 at Tower Hill becoming a bi-directional road? I note that a new set of points has been removed, but please can someone clarify why? Have had a search of this thread but unable to find anything as to why.

I note that a new set of points has been removed, but please can someone clarify why? Unfortunately the installation wasn’t quite to the correct standard and will require some reworking to solve the issue, therefore points 9/10 have not been commissioned. |

What is the next part of the ATO on the District Line to come into use? currently there is no real difference Stepney Green to Sloane Square, if anything, it has made the trains slower!

SMA 5 from Sloane Square/Paddington (C&D) to Olympia, Barons Court and Fulham Broadway currently forecast for commissioning in November 2021. As mentioned up thread, CBTC is running trains to the existing timetable with its inherited running times which is why there is little noticeable difference at the moment. |

When will the next Eastbound section be done? that's will be a big one that in terms of speed as pretty much straight line Bromley by Bow to Upminister, wonder if can compete with the C2C, even now with 40mph C2C still speeds by, also once new timetable in with the CBTC be going at speeds like the Northern/Jubilee Lines? or no chance? |

SMA 6 (Stepney Green - Becontree) is planned for February 2022 and SMA 7 (Becontree - Upminster) for April 2022 subject of course to the usual caveats. When it comes to speed uplifts, it can only go so far before frequency starts to be impacted. Provided frequency and infrastructure limitations aren’t an issue, anything up to 60mph is possible. Indeed the Metropolitan line has target speeds very close to that between Baker Street and Finchley Road as part of SMA 2. |

I reckon it will hit a 60 between Dagenham East and Elm Park, the rest can be 56mph (Upney - Upminster Bridge and Plaistow - East Ham). If not it would be around 40-50mph with the exception of Bow curve.

From Sat 12 June at Barons Court 26A/B points will be plain-lined, thus preventing westbound District trains access to the fast (Picc) line and Barons Court siding.
Signal WD43 Barons Court WB starter will have it's route indicators removed between then and September.
23A/B points at Hammersmith, EB fast to local (thus preventing EB District trains access back to the local) will be removed in September.

26 A/B points 4 foot and 6 foot points machines to be decommissioned and recovered. Is is unusual to have different points machines on each end of a crossover and are these a one off or is this common ?

That got nothing to do with it It was included as a point of information as not everyone will know that the District line signalling at Hammersmith is no longer controlled by District Line signallers. |

More flexibility being removed from the District Line in the name of Upgrading the railway ! Earlier in the thread there was some discussion about a descope of later sections of the project, there has now been a discussion to restart parts of it but not the full scope as originally planned. The intention is now for CBTC to go as far as Stamford Brook, which would prevent the District and Piccadilly sharing each other's tracks between Hammersmith and Acton Town. To that end, it makes sense to remove the connections at Hammersmith. My personal view was that Stamford Brook was a rather pointless place to have a boundary, as it's too far from any reversing points in the event of a train failing to change between modes and provides limited benefit over and above the existing signalling... but the decision was made by others! 26 A/B points 4 foot and 6 foot points machines to be decommissioned and recovered. Is is unusual to have different points machines on each end of a crossover and are these a one off or is this common ? It depends a bit on the age of the site. At somewhere like Acton Town, which has been altered piecemeal over the years, it's quite common (I think prior to Christmas 2020, every crossover had different mechanisms installed at each end). Somewhere like Barking, which was completely remodelled as part of a single scheme, will have a lot more commonality between point ends. |

I feel like it would have been way better that the revival of the project be up to Hammersmith instead. At least the Piccadilly can serve the District line stations in case of any long or large closures up to Ealing Broadway...but I guess the benefits of total segregation would be streamline services I guess...the East Putney boundary is reasonable, just before convergence with National rail services.
I don't have memory whether there are still crossovers at Putney Bridge, but I guess if any work happens beyond East Putney it would be a good terminus too utilising the points at Putney Bridge.

There are no longer any reversing facilities at Putney Bridge or East Putney Similar to the scheme for crossovers between Embankment and Westminster, there was also a plan for new crossovers between Parsons Green and Putney Bridge. I think both now out of scope. The S stock CIS has retained Putney Bridge and Westminster as destinations, just in case either revived later. Embankment is available and used sometimes.
With the Hammersmith plain lining, Hammersmith (Dist) and Barons Court CIS destinations are probably redundant. Similarly Hillingdon, as the direct route to Uxbridge Sidings was removed a while ago.

The Hammersmith EB destinations are not available in ATC, although they will remain available for manual setting on the trains. I guess the ATC would call the train as terminating at West Ken, assuming the ATC ever progressed to west of Barons Court anyway of course. Stamford Brook seems to be the target now.
