If you take all the extra electrification currently planned, plus i am going to add in Sheffield to Moorthorpe/Doncaster as this is basically rumored in Modern Railways to be announced within next 6 months as an extension. So this will cover how many DMU diagrams will become electric over the next 9 years. And in-case of any franchise remapping i am to include TPE services too.
From the NW scheme. All Northern Services between Manchester victoria and Liverpool Lime Street, this will include those extended beyond Man Vic to Stalybridge. All Liverpool to Preston services, inc those that go on to Blackpool north. Manchester (either station) to Preston & Blackpool North/Lancaster. Any services beyond to Barrow will have to be DMU operated. All TPE services to Scotland to become electric.
Transpennine, will allow only the current Newcastle service to become electric however, and this is a big however. There is a complete recast coming and the initial plans indicate 6 TPE services an hour. 2 Newcastle to Liverpool EMU ,2 York to MIA EMU, 1 Selby to Piccadilly and one Hull to Piccadilly DMU.
Then in addition, this will allow Leeds Huddersfield stoppers to become electric as well as Huddersfield Manchester stoppers (withdrawn then re-introduced to Piccadilly).
MML (sheffield) two possible services, Sheffield-Leeds via Moorthorpe and Sheffield-Adwick.
But and again a big but. I would not expect things to stay as they are, there are going to be some fairly huge changes to services across the north of England over the next decade. And out of the other side will come a rail system that frankly we will be proud of.
The illustrative options already include doubling of frequencies to half hourly with 4 car EMUs on most lines electrified out of Leeds.
