I know that there was an upgrade/replacement of the three sets of points just east of the station. When travelling through ECT yesterday, it seemed that some of them had actually been moved slightly further east too? Could anyone confirm whether this is in fact the case?
On my return journey from South Kensington back home, when switching from the WB main to platform 4 at ECT, there was also not the usual slow down before switching track, it was at a higher speed and much smoother, also linking back to my initial question.

I believe the turnout speed has been increased (25 or 30mph?) made possible by the elongation of the "sure lock" trailing crossovers replacing their air worked predecessors. The new elongated track layout would mean that the area taken up by the junction along with protection signals as you say, has shifted eastwards.

It has all been shifted with long switches this would give you the quicker speeds but I don't think in the peak you will notice the higher speeds into platform 4 due to the frequency of the trains.
Normally EC31 route 1 is pre selected with the programme machine and the Surelock's take approx 4 secs to move from Normal to Reverse so if the signaller decides to route a train into Platform 4 manually this would be slower then when air worked points were in operation.
The ride should be smoother as its all brand new with no track bounce and less joints in the track itself

Are the track infrastructure upgrades in the vicinity of Earls Court now done, or is further work anticipated?

Something I read somewhere else makes me suspect that there will be another closure at Christmas 2018!
btw, I assume that ECT is Earls Court?

There will be another set going in and putting a crossover on the westbound so a train from High St Ken can go into platform 3.
They should replace aswell 2’s points as they are now the only air worked set left at Earls Court.

Are No.2 points on the EB arm of West Kensington Junction?

Are No.2 points on the EB arm of West Kensington Junction? They're the points by which the eastbound line from Olympia joins the main from West Ken, I think that's what you meant. www.districtdave.co.uk/html/earls_court.html |

The ability of trains from HSK to go into platform3 is good, especially if its going to Olympia or Richmond / Ealing Broadway (admittedly the last two destinations are somewhat rare). I suppose that there is a good reason for switching to electric points, even if they are slower, however from a nostalgic point of view the sound of air worked points was always one of the features of the Underground system so their loss is 'bittersweet'.

Only the main Surelock unit is the same, as yet the Siemens back drive is not being used.
The use of mechanical cranks and rodding is still used at present and is known as the Balfour Beaty supplementary drive.
This is shown in this video but please ignore the set up of cranks we do it differently and of course the points in the video are Clamplocks not Surelocks

They should replace aswell 2’s points as they are now the only air worked set left at Earls Court. The proposed crossover from High Street Ken to Platform 3 is often talked about but isn't going to happen. The logical time to have done it would have been in this closure to form a modular scissors with no. 30 crossover. There aren't any plans to do 2's crossover either, sadly... but it's on my wish list! By the way, we don't use the BB07 (Balfour Beatty) supplementary drive any more, we use the PRS12 (Progress Rail Systems) one instead. |

Is this the one with the round stretcher bars what NR are putting in everywhere now? Wasn’t 2’s forgotten? The crossover from HSK to Platform 3 is still on there master plan take it this can be ignored now? |

Not quite, the PRS12 uses a tubular rod between the cranks whereas the bb07 used a square one. We aren't yet installing the same design of stretcher as NR.
I'm not sure whether or not 2's ever fitted into the strategic plan, but it seems a bit odd to not do it!
I think it's safe to remove the extra crossover now, there are other parts of the 2011 End State plan that also won't be happening, like single-tracking from HSK to Triangle Sidings (which seemed really odd at the time!)

It still uses the Balfour design cranks as opposed to the original Westinghouse design I know what you mean to the square rodding between the fixings.
Never heard about the single track layout around Triangle don’t see that working somehow.
Was looking at the new stretcher bar design seems more robust easier to fit but hey LU are around 10 years behind in some aspects this being one.
