I think this is two services - the Llandudno service mentioned would be via Runcorn.
Can you supply a link to this information showing a proposal for a Wirral Line extension to Llandudno? I doubt that city region partners would be happy having their strategic priorities dictated and their network mutated, solely to take north wales over some electrification BCR finish line.
The consideration of extending Wirral Line services onto any electrified North Wales line didn't go as far as Llandudno, Flint was looked at though, basically commuting distance from Liverpool, as it relates to North Wales and M56/M53 corridor.
The first thing to be abundantly clear about - the city region partners are not having their strategic priorities dictated to by anybody, it's an option that Network Rail had looked at to provide an option to funders, of which the city region partners are considered to be.
Merseytravel, local authorities in North Wales, and the Welsh Government have been working on additional routes and additional capacity from North Wales onto Merseyside. The Halton Chord is the most high profile of this, but work has also looked at what benefits and drawbacks result from extending electric services from the Wirral Line along part of any electrified North Wales Coast line.
It's absolutely not a case of forcing Merseyrail to operate services on any newly electrified route, it's about whether it would benefit them if they wanted to do so. Would it benefit their rail service now, would it deliver modal shift, does it open up new housing and development options and so on. There's never been any suggestion any extension to Merseyrail would be forced upon Merseytravel.
The BCR for the North Wales Coast electrification from Chester to Holyhead is poor, but to improve the business case, the Welsh Government specifically asked that additional train services be modelled, over and above the current services which would convert to electric (those would be the London Euston to Chester/North Wales, Manchester Piccadilly to North Wales and Crewe to Chester services).
The additional services modelled were extending all London Euston to Chester services out to either Bangor or Holyhead, an additional Manchester Piccadilly to Llandudno service and a new direct service between Liverpool and North Wales. The Liverpool to North Wales service proposed is unlikely to be routed via the Wirral Line, of course, but all options have been considered. It might have received a firmer proposal to be put to funders is new rolling stock with known technical capabilities (25kV future capability or delivered with dual voltage capability) was known about when the Draft RUS was drawn up.
If you want specific page numbers in the Draft RUS, just ask.
As I say, when you said "we" who are you talking about?
And for the bit in bold, yes, again, can you provide the link please. If you also want to provide the page numbers then great.
As it stands you haven't even specified which draft RUS you're referring to.
I see perhaps CLC conflicting with priorities to bring the airport online, and then "city line" electrified services creating issues of duplication. I could well imagine instead the northern line terminating at the airport (calling at liverpool south parkway on the way to it), with instead a vastly improved city line service passing through liverpool south parkway from Warrington Central. Each line having six trains an hour perhaps.
Welsh RUS refresh (also referred to as the Welsh route study) from March 2015. It's on the NR website somewhere, you'll need to have a look and find it.
Relevant page numbers would be Page 47 for North Wales Coast electrification and ITSS, Page 88/90 for North Wales coast electrification options. Table J for Halton Chord discussion, and reference to Conditional Output CO28 which considers the old Wrexham to Liverpool via Bidston proposal, appearing to be discounted for now, and favouring the routing via Liverpool South Parkway so as to provide airport connectivity.
CO28 has an obscure reference to incompatibility between diesel and third rail being a barrier to service (as it always has been, and why the Wrexham to Birkenhead North services never happened despite being reviewed in the Merseyside 2009 RUS).
I guess you're well aware of the older proposals (which completely avoided inclusion in the updated Wales RUS) for the Borderlands line to be electrified and merged into the Wirral Line, and operated by new dual voltage rolling stock ?
OK, here you go: http://www.networkrail.co.uk/long-term-planning-process/welsh-route-study/
As expected, no mention anywhere that I can see of connecting anywhere in Wales other than Wrexham to the Wirral Line. Would you please point to the page where Flint is specified as a potential end destination for Merseyrail?
I've already said it was something that was looked at but it's not in the Draft Wales RUS refresh at this stage, it's effectively in the same category as the electrification of the Borderlands Line which was considered as an extension of sorts of the Wirral Line, something that has been looked at and considered, but not brought forward to date.
I can only tell you what we've looked at, not what was progressed through to the route study to present to funders. You'll note earlier, I specifically said it might have been something that would be put forward to funders had the rolling stock strategy being pursued by Merseytravel been further developed at the time.
Now, what else can I help you with, or are you simply out to be contrary for the hell of it, or maybe you're just completely underestimating and failing to understand the work Network Rail put into reviewing the proposed electrification of the North Wales Coast line in order to put the proposal to funders.
You need to look at the work we've done on electrification of the North Wales Coast, additional electric services are the only way to get a BCR close to what would conventionally be approved. That's why additional services to Llandudno have been modelled and why the extension of some services from the Wirral Line have also been modelled.
There's a bit in the Draft RUS with recommendations to funders.
If you want specific page numbers in the Draft RUS, just ask.
Who is wasting whose time here.
My guess is that further electrifcation is more likely to reduce the size of the Merseyrail franchise and not increase it. I doubt electrifcation of the borderlands line, Kirkby-Wigan, Ormskirk or a tunnel linking the city lines to Liverpool Central will happen. However, electrifying the CLC is likely in the next 10 years or so. Current policy is to replace 3rd rail with overhead when sensible and retaining 3rd rail between Liverpool South Parkway and Hunts Cross doesnt make much sense. Its possible that Merserail services could be extended with dual stock but there are already capacity issues on the northern line and it would be easier to cut back Merseyrail services to Liverpool South Parkway and serve Hunts Cross with current and new Northern services and peak time express stops. Southport to LSP is currently 59 minutes and new stock would add enough buffer time. Most services are 6 coaches so this would save 4 x 3 car units.
Edit: 62mph speed limit is possible but it would make a noticable difference to some routes, Bache-Hooton would probably take an extra minute and there is only 3 minutes turn around time in Chester, this section was upgraded from 60mph to 75mph in 2011 to add extra buffer time when Liverpool to Chester went 4tph. 100mph is unnecessary but 75mph is a minimium, politically it would be a hard sell to replace 1970s trains with ones that have a top speed that is signifcantly lower.
I wouldn't be so pessimistic about the City line connection tunnel. There's a limited amount of space available at Lime Street and it'll need to handle more and more express train services. Even without other rebuilding/gauge-clearing work for HS2, trains will be longer and more frequent. Building the link tunnel would save you the hassle of needing to keep platform space available for local services which would be better running through the Merseyrail tunnels. It also allows you to dedicate two of the tracks up to Edge Hill to HS2/NPR services, leaving the other two for residual classic line regional and express services.
Though you're then shifting the capacity issue to Liverpool Central (higher level) where platform space is at a premium. A solution could be to extend the Ormskirk and Kirkby services onto the City line (Warrington BQ, Wigan, Warrington Central perhaps?) but if extending all 8tph that's a lot of space to find. Chester via Halton Curve is another option as is Ellesmere Port, Crewe via Runcorn and Hartford is probably a step too far though.
As you said though, this isn't an insurmountable problem. Solving it would have other benefits for the city as well, unlike just expanding Lime Street. If despite all attempts you end up with an unbalanced service pattern, then you just need to put a turnback siding in some convenient spot. You could have a turnback at Edge Hill, just before the Merseyrail tracks merge into the normal NR network.

Ideally you'd want a standard service pattern, but there probably isn't capacity for 4tph on any of the City line routes, so perhaps something like alternate Ormskirk services extending to Chester/Ellesmere Port, with Kirkby services alternating between Wigan NW and Warrington BQ.
Passive provision was originally made for an extra higher level platform
In what form exactly? The existing "low level" platforms are only just below ground. Though there is I believe a small tunnel that runs parallel to the present platforms on the same level, I've seen old diagrams showing it.

I believe they are just headshunts into a new tunnel at both ends. You can see the northern one from the train shortly before entering the station. As I understand it, a new tunnel would have to be built under the booking hall.
