I got the impression that the track alterations were needed to enable the closing up signal, but I’m not sure how??The closing up signals etc could presumably be delivered without a full closure during a regular resignalling.

Cant they be extended to Manchester Airport ?Where are they going if they don't? You are adding more trains into 13/14 and where do you send them afterwards?
It just seems to be an awful lot of work, disruption to incorporate a central turnback!
Remember that only the station will be closed for two years. This site is in the middle of a busy city and needs to keep the railway (mostly) open, so two years isn't bad.My only hesitation is the estimated timescale involving a closure for two years. That need to be reviewed.

You have a Southport terminating at xx.15 and a Lime St terminating at xx.33. You need a 2 minute dwell at Oxford Road so the xx.15 would go at xx.17, Picc between xx.19 and xx.21, Slade Lane at xx.24. You just follow the Blackpool down to the Airport and have the TPE right behind you. There is no guarantee it fits at the airport either.Cant they be extended to Manchester Airport ?
The Calder Valley was supposed to have direct services at one point. If 13/14 at Man pic is the issue then perhaps investment should be poured into resolving that.

Its not a scheme to solve that.To me, this scheme seems like trying to polish a turd. The Castlefield corridor has always been a massive bottleneck, and this scheme will not provide the capacity upgrades required to alleviate this. Nor will it enable the Ordsall Chord to be properly utilised. The only thing it might do, is enable operators to run slightly longer trains along the line. However, in my experience, TOCs tend towards running shorter trains more frequently, so this benefit may not be utilised by most operators.
For the full Ordsall Chord service you'd need four full platforms at both stations, not just Piccadilly. That's not affordable. I've worked the route for years and know from experience that most of the delays I've racked up have been queuing to get into Oxford Road from the North.Well at the time of the Ordasll Chord debacle it was stated or widely acknowledged that to run 4 tph over the chord platforms 15 and 16 were needed at Piccadilly. Now it is Oxford Road that is the main problem. There was either incompetence then or incompetence now, both scenarios cannot be true!
What will that do to dwell times? A colleague directed a few choice words at a signaller when the bobby asked why his train was taking so long to unload - what did he expect when he sent an overlength peak train into Platform 1? Bear in mind that if 350s do end up on Blackpools their selective door system is primitive, AIUI you can only select complete units, so anything less than an eight car platform means only four coaches on. Even with an eight car unit fitted with ASDO, shuffling the contents of the front/back two coaches out of the third will waste time.Well not if the stop boards were positioned to put the overhang at the east end of the platform.
In view of the limitations, yes it is. In an ideal world there would be funding to widen the viaducts and provide four full length platforms at both stations. Until then...I seem to be very much in the minority in thinking this is a well thought out and sensible scheme.

Providing longer through platforms and a centre turnback platform produces a much better layout than exists currently, especially in conjunction with wider platforms etc.
The current practice of undertaking crew changes at Oxford Road needs to cease - it is an ongoing performance liability. Hopefully closing the station to passengers for an extended period will force the relevant TOCs to make alternative (better) arrangements.

I do wonder how many of the people dismissing this proposal have actually worked on the development of multi-disciplinary rail projects, and/or have relevant professional qualifications (or experience equivalent) in signal engineering, permanent way engineering or operational planning.

Regarding crew changes . I can see how Bolton or Salford Crescent (when its extra platform opens) could be used for traffic coming from that direction ,Stockport for things coming through there and thinking about future service patterns stalybridge .
Not sure about stuff coming off CLC or Chat moss though unless through stuff to the airport sees crews change there and turnback services at Oxford road are only allowed where the same crew works them in/out .
Alternatively of course moving traincrew depots in Manchester to oxford road or very close by would also see crew changes become more reliable . That being said there are crew depots at Picadilly already and changing crew there isn't permitted .

In fairness to Network Rail, the chord only became a fiasco because the government of the time ripped out all the other parts of the plan that made it workable - after construction on the chord had already started.The Ordsall Chord fiasco is not exactly a good recommendation for Network Rail's expertise though is it?

Two thoughts: I haven't seen it written that TPE will get 200m-long sets after TRU. Wouldn't other stations have a similar platform length issue?And longer, wider platforms. Which will be necessary when newly electrified TPE goes to 200m trains, unless you want it to just have a sparse service of Northern stoppers only like Deansgate does. If not done it might even mean some peak Blackpools not stopping if they go to 8-car.
Which then raises questions about why Network Rail prioritised a section of the scheme that was essentially worthless alone.In fairness to Network Rail, the chord only became a fiasco because the government of the time ripped out all the other parts of the plan that made it workable - after construction on the chord had already started.
Sure , but can it only go there after the track changes?There will be a signal at the entrance to the platform.
TRU are working towards 7x26m for TPE (182m)Two thoughts: I haven't seen it written that TPE will get 200m-long sets after TRU. Wouldn't other stations have a similar platform length issue?
And: the document (unless I've missed it) only says "six" and "eight" carriages, without specifying if these are 195s, 802s or something else.
(Apart from the two-year closure, I'm in favour btw.)
YesSure , but can it only go there after the track changes?
I've absolutely no experience in any of those things, however I do have not insignificant experience of watching people build hospitals, schools, offices, nuclear waste handling facilities, leisure centres and large infrastructure projects which all seem to run into entirely unpredicted issues which seem fairly obvious to everyone except those managing the project.+1

In government? Unlikely, I'd expect.And perhaps some lessons have been learned?
I find myself waiting in both directions. Usually a southbound TPE (punctual as they are) goes into P4, causing the stopper in P5 to have to wait for the sixth coach to clear the points before it has a path out. If/when the Norwich-Liverpool it follows is a few minutes late then that really throws a spanner in the works. The signaller really needs trains in both directions to be punctual in order to path the stopper out of the bay without fuss. That doesn't happen as often as it should.I find that most days I spend longer waiting at Deansgate in the Up direction for the service ahead to depart platform 4 towards Piccadilly than I ever do for the supposedly problematic conflicting moves from platform 5
Not convinced it was Network Rail who prioritised it. They are in no way blameless at all and should have pushed back, but it was the funding providers who prioritised it as far as I am aware.Which then raises questions about why Network Rail prioritised a section of the scheme that was essentially worthless alone.

The other aspect is that without the conflicting move you gain a path, which would allow the Warrington Central stoppers to go back to half-hourly.
Presumably the overlaps. After arriving in 3 you have to wait for them to time out before the route for the following train can be set into 4. No such issue in platform 5. If 3 gets turned into a bay platform then it likewise will cease to be an issue. With the current track layout, 3 has the same conflicts at the north end as 5 does.Is there a reason why the stopper doesn't use 3 more routinely ?

I posted a diagram of the current layout in post 20 above.Thanks, that is interesting. I had no idea that a train leaving 3 Northwards would still impede trains entering 4 (If I'm understanding you correctly).
