Yes that's what I intended to say actually. If trains can accelerate and decelerate way quicker that means the usual maximum speed could be achieved on these sections thus reducing a little time as it has averagely travelled faster. But of course, if the usual maximum is easily achieved, there is potential to further increase it, such as Dagenham East to Elm Park for example. There has been improvements on average speeds between Ladbroke Grove and Paddington, as well as Baker Street to Euston Square.

Is there any news on how speeds or journey times have improved with the testing? maybe for the exception of junctions, but for up to SMA2 it seems to be faster on the loop, roughly no difference between Finchley Road and Baker Street tho. I suppose we can wait for SMA7 for speed SMA3 is commissioned as planned 6-7 March, the hope is to introduce new Working Timetables from 16 May 2021 September 2021 Nothing much planned for District, except timing adjustments for H&C and PICC re-timings. On the MET and H&C suggests "faster CBTC run times Hammersmith/Finchley Road-Aldgate/Whitechapel/Tower Hill" |

The SMA3 operational proving weekend is now complete and has been deemed a total success. This paves the way for go live to proceed on the weekend of 6th & 7th March.
The railway is now being converted back to conventional signalling ready for the start of service tomorrow morning.

Exactly what I was hoping for on the section of track between Stepney Green and Mile End! |

That's one of the potential sections that will have reduced journey times, and maybe even have a little higher max speed set once it is stable. Edit: I apologise for the weird floating things around quotes as I am still a noob at adjusting quotes. If any kind soul would like to educate this aged-too-young boomer please do so. |

I have seen an email on a railgen site saying that this coming weekend another chunk of the SSR will be automated.

I have seen an email on a railgen site saying that this coming weekend another chunk of the SSR will be automated. Commissioning of SMA 3 - Euston Square to Stepney Green and Monument. Circle, Hammersmith & City and City bound Metropolitan line services will henceforth spend over an hour in CBTC and the District line proper gets a real taste of the Thales treatment. Of note is Liverpool Street Interlocking Machine Room (IMR) which will be switched out for the final time this weekend. The building that houses the IMR has been in use since 1875 first as a signal box (re-fitted 1910 and 1954), then as an IMR controlled from Farringdon (1956-2001) then Baker Street (2001-Present). |

I doubt that it will be preserved Whitechapel will certainly be cannibalised to keep other N style frames still on the network in use.

Lever frame inside (Westinghouse B-style) is a strange creature but I’m not aware of any plans to preserve that. |

Look forward to riding through SMA3 after the stay at home order is lifted on Monday! Excellent to see the project delivering operational railway again after the pandemic caused so much strife last year. Big kudos to all involved in working through all this.

With automation creeping further around the Circle I am looking forward to bring able to get views of ground signal EH900 at Embankment in action. Years ago I recall watching a similar signal at Whitechapel but it was removed before I got around to filming it. Why? The same reason as I filmed things like bulb lighting lampshades 'many decades ago'. Future nostalgia etc... I doubt that it will be preserved Whitechapel will certainly be cannibalised to keep other N style frames still on the network in use. Hmm, well I suppose that it makes a change from having to ask a museum to remove items from a display so that they can be used as a source of spare parts!

So it is almost time to say 'bye bye' to this signal - but what about the rail gap indicator?  C-LiverpoolSt-P1120837One of many photographs which I added to Flickr yesterday (1st March 2021). |

You’ll need to be quick for signals EH900 and EGX8400 at Cannon Street due to go with SMA 4 on 24/25 April 2021. At Liverpool Street signal OD 4 will be replaced by CBTC Hold board MRG 011 and a new rail gap indicator with be provided, replacing legacy equipment. |

(I'm generally of the opinion that Old Stuff be preserved, but also see the value of having a parts donor.)

Is there a 'soft date' for SMA5 or any others after SMA4?

Paddington (Circle), Finchley Road and Euston Square.
If all goes to plan Euston Square will be replaced by Stepney Green and Monument.

S.M.A.3 { Stepney Green to Monument or Euston Square} has gone live as of this afternoon
Service will be advertised as closed in line with engineering works
However will be open to customers at stations

How advanced is the on track and trackside hardware installation at present? Into which SMA areas can physical hardware be considered mostly done, with testing and the like able to be considered later in 2021?

How advanced is the on track and trackside hardware installation at present? Into which SMA areas can physical hardware be considered mostly done, with testing and the like able to be considered later in 2021? SMA 4-7 have had dynamic testing undertaken. That entails the southern half of the Circle line back to Paddington via Victoria, the "austerity" western limit of the District line at Barons Court/Fulham Broadway, the eastern remainder of the Hammersmith & City line and the eastern extremity of the District line. The latest board papers this month cite progress in the Neasden area with regards to the readiness for testing within SMA 8. During journeys made this week, I've seen some CBTC related infrastructure installed in the Rayners Lane area part of SMA 14. |

Anyone notice any key differences, especially on the journey between kings cross and Farringdon?
Also, I know there's a clear reasoning for doing so but I cannot understand why the Met requires ATO north of Finchley road 😂
Some trains do each in excess of 62mph on some sections of the met (e.g. Finchley to Wembley) and I hope ATO does not slow this down

London Buses are accepting Tube passengers in Zones 1/2 because of signalling issues in the Aldgate area. Request time at 16:59.

Between Finchley Road and Wembley the maximum permitted speed is 60mph and S Stock are limited in maximum speed in manual operation. |

Between Finchley Road and Wembley the maximum permitted speed is 60mph and S Stock are limited in maximum speed in manual operation. Back in the day when I sometimes got myself into the cab (on my way to school) of westbound Amersham trains I recall the train often going faster than 40mph between Farringdon and Kings Cross. As for the route north of Finchley Road, will there still be an enforced stop for all trains - even when on what are supposed to be non-stop runs - at a location away from a station for swapping between manual and ATO? |
