What's wrong with token working?
It's slow, inefficient and labour intensive.

Works well between Rainford and Kirkby .....trains reach 70 mph. The token handover takes a matter of seconds between 1 signaller and 1 driver.
SO the trains reach a slow speed and and it requires a signaller at the token handover point?
So 30mph slower than they could be doing, not counting the required decelleration, and one more signaller than is actually required in a modern system?
No......trains call at Rainford station and then travel about 20 yards or so to the token point. Removing this wouldnt achieve any time saving whatsoever. A recent addition into the mix is a freight train run.
In my experience the primary issue is the short trains.
If all the Pacers were actually 3-car Class 172s, and the 185s were 5-car, and the new TPE stock was to be 8-car sets etc, and a few more wires went up, it'd be just fine, I reckon.
A freight train has to slow to a stop when it would otherwise be free to proceed through the station at line speed?
A 20 yard crawl to the token exchange point is still an operational inefficiency that could be dispensed with.
And a manned signal box is an expensive way to run a railway today - controlling one additional block section has a marginal cost of a small fraction of a signaller using modern equipment.
Modern equipment would also permit the freight trains to be flighted with a passenger train on the branch - which significantly improves operational flexibility and reliability.
Thats about the sum of it. We dont need a grandiose grand projet. Tweaks to track alignment and a few more stations being re-opened, together with a commitment to future electrification, will help to keep people happy. But most significant in northerners perception of their railway system is the quality and quantity - of the rolling stock. There is a chicken and egg situation here as around the north rail has to compete with other modes of transport. It is feasible, for example, for someone in a fairly low-paid job to drive into Manchester and be able to afford to park for the day on the periphery of the city centre. Rail has to offer an attractive alternative.
Also I wouldn't say there is any need for anything to be more frequent than every 15 mins. If more capacity is needed it should be done by train lengths. I'm not sure we need 6 TPEs per hour. Two to Liverpool, two to Manchester Airport, but each with 5-6 carriages would be sufficient at off peak times. This would leave more room for local stoppers which should be 4 cars rather than the current 2 and could perhaps run twice an hour rather than the current hourly.
Bradford, the 10th biggest city in England is only served by slow stopping trains plus four GC trains a day to London which take over 90 mins to get to Doncaster and a slightly faster Virgin one which doesn't run off peak. It has no direct connections to Liverpool, Sheffield, Hull or Birmingham. Bradford will not get a spur to HS2 and is unlikely to be on the route of HS3.
It would currently take me well over 3.5 hrs to do my fortnightly trip from Ellesmere Port by train and 4.5 hrs door to door. So I drive. Roll on Northern Connect which should offer some improvement.

It does.....numbers have been growing over the last few years or so.
Looking at this question from a slightly different angle. Are there two large cities as badly linked together as Manchester and Sheffield in the rest of the UK?
Oxford and Cambridge?
In all seriousness, the North's web-like service, if slower, allows far more journeys that aren't just to one big city compared with the South's which is basically all about getting to London, with other markets very much secondary or even completely unserved.
As for Manchester-Sheffield, all it urgently needs is longer trains. I've used it and I don't think it's a bad service per-se.
Not quite....the box sits on a junction with a 15mph speed over the points from double to single track. The crawl would still be there. Whilst I understand what you are saying , what struck me just the other day when i was down that way was considering how old fashioned this system is, its also extremely simple.
Well that is unfortunately some sort of chicken and egg problem - if the trains have to crawl there anyway for the changeover there is no need to increase the junction's speed.
Simple systems are not the best these days however - it is worth noting tha electrification and a more modern signalling system would likely allow two trains to run through from central Liverpool to Wigan Wallgate without adding any additional trackwork.
The frequency of services through Helsby to Manchester and North Wales are fine and we will soon be back to the 70's with through trains to Liverpool via the Halton Curve and services to Man Vic in the peak. For a very small station I'd say that direct access hourly to Liverpool, Manchester, Chester and beyond is very good.

That's an irrelevance: what you are (now) talking about is the matter of upgrading and centralising signalling, which is separate from whether token working is good or bad. Large-scale investment needs to wait its turn.
Without additional trackwork?
I take it you're ignoring the buffers, bridge and lack of track between kirkby (northern) and kirkby (merseyrail)
When I take a little tripette out to Matlock, the driver seems to manage the process pretty well and takes only a minute to do so, and that's without a signaller to help. Its down side is when the token exchange takes place away from a station stop but I imagine there can't be many of those left. I'm not sure how it would ever be labour intensive.
Looking at this question from a slightly different angle. Are there two large cities as badly linked together as Manchester and Sheffield in the rest of the UK? One route closed and ruined by some extremely short term planning and the other one has a single track at one point. (Plus terrible road links that are both single carriageway and at the mercy of the weather) Links to the East Midlands are poor too from the North West. Both journeys from either Liverpool or Crewe trundle along very slowly.

There was a brief report on Northern Powerhouse on the Beeb this morning and I was pleased to note that the presenter mentioned that every time this subject is covered she gets messages that rail investment in the south west and midlands isn't that brilliant either. I don't begrudge rail investment in the north as long as the rest of the country is not ignored.
