Platform edge doors can only be installed on straight and level platforms. Jubilee Line Extension platforms at below ground stations meet these requirements. You can't turn back time. Not true. The Paris Metro's retro installing PEDs on curved platforms in preparation for their driverless trains. www.therailengineer.com/2012/02/28/paris-metro-line-1-a-new-beginning/

The Piccadilly did it again today (Thursday, 19 July), a shuttle ran between Acton Town and Ealing Broadway for a couple of trips.

I think the T/Op was playing silly buggers!

I would like the Piccs withdrawn and terminated at Ealing Broadway leaving the Rayners Lane Branch to be taken over by the District S7's We were saying exactly the same thing only a few days ago. Makes more sense now that the Met and District will be using the same stock. Then the Picc could concentrate on the Heathrow service.

From what I've been told, there's been 10 minutes taken off a round trip. The line's significantly faster since the new signalling was introduced.

Were the trains used on this temporary shuttle borrowed from the regular Picc service? One service train was taken for a round trip, so the effect on the service was negligible.

The Ealing Broadway - Acton Town shuttle was done as a 'spur of the moment thing' by Piccadilly line service control.
The District line was so broken they'd not had a train up to Ealing Broadway for over 40 minutes, with no prospect of getting one any time soon. Most of the District line trains were blocking back between Earl's Court and Whitechapel.
So the Piccadilly line stepped in to help get the customers from Ealing Broadway down to Acton Town.
It was a Piccadilly line driver with a DRM acting as a pilot with the train making five round trips in all.

You're correct in saying that the four proxy locations are relatively new. Prior to Leicester Square, about four years ago, the proxy was taken at Barons Court.
Regardless of the loading of trains, any railway should be regulated to even up gaps. Failure to do so only leads to problems later in the journey. Trains bunching up is no good for anyone.

Finsbury Park westbound, Hammersmith east, Sudbury Town east and Hounslow West east. Interesting, thank-you. I wonder why that makes it 'accurate'? Mileage-wise there's a bit of difference between Sudbury Town EB and 'ounslow W EB, perhaps it's a function of the number of berths and speed in front before Acton Town. Likewise with the two into Zone 1; FP WB is a curious one, as I can't remember there being compensatory stand time there - although the times for runs down from Turnpike Lane used to wander around a bit. I shall have to have a think. Don’t look too closely for a scientific reason those particular sites were chosen! Finsbury Park west is an indicator of the westbound service going into London. Incidentally, that site gives problems with the proxy score as the balance headway’s still in effect. Missed headways can be caused simply by the balanced headway holding a train for thirty seconds longer than anticipated as the threshold for a missed headway’s quite tight. Sudbury Town eastbound gives an indicator of the service coming back from Rayners Lane and beyond. Piccadilly line trains are often held up by the Met, so the proxy score is taken at Sudbury Town to reflect those problems. Hounslow West east gives an indicator of the service from Heathrow. Hammersmith east is an indicator of the overall service going into London. The average of all four sites then gives us the line proxy. As you can see, they really were chosen to give a true picture of the service provided by the Piccadilly line.

Regarding crowding and regulation of the service, the location from where the headway scores are measured don't know how busy the platform is - all about targets! Not true. The Piccadilly line's measured at four separate places chosen to give an accurate reflection of the service.
