The Manchester Hub (now renamed Northern Hub) is option 2 of the Manchester Hub Rail Study Report produced by Network Rail in 2009.
This was almost complete when the unexpected announcement of the Chat Moss electrification was made and the report states quite reasonably that the plans would have to be reviewed in the light of the electrification announcement.
The Northern Hub is more than just a renaming of the Manchester Hub. As you have said yourself the Manchester Hub didn't include electrification. Now any rail improvements in the North seem to be put under the 'Northern Hub' category.
There were actually 3 separate rail projects proposed by the previous government for the North of England, in addition to the Manchester Hub:
1. Improvements to the 10 worst mainline stations in the country, which were mainly in the North, such as Manchester Victoria. This was cancelled by the Coalition government, however, some of the Victoria improvements are going ahead under the Northern Hub.
2. Procurement of new DMU vehicles for extra capacity to be in service by December 2012. This was cancelled as a result of a realisation that if new vehicles were ordered for Thameslink that there would be numerous vehicles sitting around spare unless they were put to use.
3. North West Electrification and refurbishment and cascade of existing Thameslink EMUs to North West.
Therefore Northern Hub predates electrification and none of its objectives are dependant on methods of powering the trains, but the methods of achieving those objectives may. The North West electrification may well be inter-related with the Thameslink project but it is not part of the Northern Hub option 2 schemes which are listed below.
- Four track Marsden Diggle
- Dewsbury Up Loop
A recent post quoting a PTE states these will not be going ahead as it will be possible to achieve up to 6 fast services on North TPE without these.
The delivery of class 319s is needed for the December 2014 timetable change but this is part of the NW electrification.
They are needed before then. TPE services will be diverted away from Bolton in the May 2014 timetable change, or possibly December 2013 if TPE get approval. The DMUs released off Chat Moss are needed to plug this gap. If there are no EMUs to replace the DMUs on Chat Moss then it causes all kinds of problems.
Originally the 319s were supposed to start being replaced in 2012, to give time for refurbishment and crew training prior to going in to service in the North West in 2013:

So what if the Northern Hub costs less than the DLR? DLR is essentially a new urban railway and Northern Hub is an enhancement to the existing lines to better use their potential capacity.
The reason I brought up DLR is because it is a much more sensible comparison for the Northern Hub, opposed to Thameslink or Crossrail.
The hugely exaggerated myth that DLR carries as many passengers as Northern, or Merseyrail and Tyne and Wear Metro combined suggests there were good reasons for spending the money.
Corrected that sentence for you.
Daily ridership of DLR is 192,000.
Daily ridership of Tyne and Wear Metro is 113,000.
Daily ridership of Merseyrail was over 100,000 before the frequency of Chester services was doubled.
Northern Rail are very short of capacity on their rolling stock and the total capacity of all their rolling stock is more than double what DLR have so I very much doubt the daily ridership on DLR is higher than Northern alone.
Will the full Manchester Metrolink be better value for money than the DLR? I look forward to your analysis of the cost and likely passenger traffic.
If you look at my previous posts on here the only tram lines I support in Manchester are the city centre lines and the line out to Salford Quays.
