A £600 million rail investment proves the Government is "getting on" with the Northern Powerhouse, Transport Secretary Grant Shapps has said.
The vast majority of the Department for Transport (DfT) funding will go towards kick-starting the Transpennine Upgrade to electrify most of the line between Manchester and Leeds.
It will also allow faster trains to overtake slower ones by doubling the number of tracks from two to four on the most congested sections around Huddersfield and Leeds.
Mr Shapps described the announcement as "very significant".
There are further plans for full electrification, digital signalling, more areas with four tracks and improved freight capacity.
Those measures would allow all-electric services to operate between Liverpool, Manchester, Leeds, York and Newcastle.
Mr Shapps said: "It clearly makes sense to be able to run electric-powered trains all the way across, so that is the direction we want to go in."
The Transport Secretary, who is also the Northern Powerhouse minister, will lead a new body designed to speed up transport investment in the region.
The DfT claimed the Northern Transport Acceleration Council will give northern leaders a "direct line to ministers" to speed up projects.
It will hold its first meeting in September, and will consist of elected mayors and council leaders.
Mr Shapps said the Government is "determined to accelerate improvements" as people in the North "rightly expect action, progress and ambition".
Mayor of Greater Manchester Andy Burnham welcomed the announcements.
Passenger watchdog Transport Focus urged the Government to ensure travellers are kept informed about what the work will mean for their journeys.
Director David Sidebottom said: "How this work is managed over the coming years will be key to passengers' trust in the rail industry."
Mr Shapps's predecessor Chris Grayling was widely criticised after electrification projects in South Wales, the Midlands and the Lake District were axed or downgraded in July 2017.
