Platform Movement Changes: S7 Stock will no longer be diverted onto Piccadilly Fast Lines between Barons Court and Acton Town, '73 Stock will no longer be diverted to District Local lines
That was what I expected to see. I don't see why in theory though a T/Op couldn't acccept a route to the Piccadilly line and carry on in tripcock, at least until the tripcocks are removed. The crossover between the District and Picc is being retained for Engineer's trains; the one between the Picc and District is being removed.
Agree in theory, but the system is not providing Boundary functions there for S stock to allow it to Exit with latch relays set for Tripcock mode. So you'd need a tech to do that with the manual device or just continue in RM which still has the tripcock and max 10 mi/h. By the time that area is fully ATC, tripcock removal is supposed to be just around the corner for S stock, but who knows what will happen that far in the future!
whilst i have seen piccadilly line trains using the district line platforms in both directions at acton town, i have never seen the district line use the piccadilly line platforms 2 and 3
I have worked District trains into both pfm.2 and 3 over the years but usually if the need to run via the fast lines is required District trains would still use pfms.1 and 4. There is now a reluctance from trainstaff to accept requests to call at all stations on the fast line, as only Acton Town and Hammersmith stations are fitted with the appropriate equipment for S Stock to stop. A total ban may come in before CBTC is commissioned.
I was on the Piccadilly yesterday and my train from Osterley arrived at Acton Town on the District platform.
Maybe though the splitting of the four tracks into dedicated lines for each Line is planned for the future (ie: not happened yet).
Don't think you will be able to split the platforms at Acton Town as pic uses district westbound to go down the local to west of Acton and eastbound platform if coming off the local from Northfields as well as use them for normal running and to put trains in the sidings . Also have to be a way for pic to use the track to Ealing common and what about when the pic takes over Ealing broadway in the future
Personally only see splitting the lines causing more delays.
I'm not close enough or priviliged enough to give a definitive answer to that question.
If things do proceed as the email from the top boss seems to suggest, then there's a weekend needed for operational proving (that's where they essentially run the full timetable within the possession but closed to the public to see if it really is ready) then another where they go live. The go live weekend is advertised as closed to the public but they'll open it up to public service on the Sunday afternoon if they are happy it's staying in.
But remember, the first SMA (Signal Migration Area) is only Hammersmith to Latimer Road. A similar process will probably be needed for Latimer Road to Paddington and the each further section as they progress around the Circle line. So I would imagine there'll be further closures on the Hammersmith/High Street Kensington - Edgware Road sections.
Testing has already occurred as far round as Monumemnt so I'm not sure whether the process will remain the same or change as they gain more experience with going live on each new SMA.
Sorry to be a little vaugue but we're at a stage where we're all waiting for somebody to make a decision and publicise it.....
