Prime Minister Boris Johnson has promised a faster rail route between Leeds and Manchester, claiming the benefits would be "colossal".

In a speech in Manchester he gave his backing to the trans-Pennine transport link to "turbo-charge the economy".

Standing in front of Stephenson's Rocket he said mass transport systems enabled people to prosper.

Greater Manchester mayor Andy Burnham said he wanted "to see real action now to back up the prime minister's words".

Mr Johnson said the full details of the Leeds-Manchester route would be published in the autumn following the review into HS2.

An audience of about 100 people gathered at the Science and Industry Museum in Manchester to listen to Mr Johnson's speech.

The prime minister set out the four "ingredients" for the success of the UK as liveability, connectivity, culture, and power and responsibility.

He said this meant areas having great public services, enough affordable homes, safe streets, fast broadband, and more responsibility and accountability for local areas.

HS2 and HS3

HS2 would connect London, the Midlands and up to Wigan, Manchester, Sheffield and Leeds using trains capable of travelling at 250mph.

The north-to-south rail line is budgeted to cost £56bn.

The first segment - between London and Birmingham - is due to open in 2026, with the second - to Leeds and Manchester - expected to be completed by 2033.

HS3 - a high-speed east-west rail link between Liverpool and Hull - and north to Newcastle was first announced by the government in 2014 but no firm commitments have been made since.

In June 2019, the Department for Transport would not confirm when a decision on HS3 would be made, but estimated it could cost up to £39bn.

He added: "We are going to give greater powers to council leaders and communities.

"We are going to level up the powers offered to mayors so more people can benefit from the kind of local structures seen in London and here in Manchester."

Mr Johnson said young people growing up "a few miles away" from the centre of Manchester had felt "hopelessness, or the hope that one day they will get out and never come back".

"The crucial point is it certainly isn't really the fault of the places, and certainly isn't the fault of the people growing up there," he said.

"They haven't failed. It's we, us, the politicians, our politics has failed them."

The Northern Powerhouse rail project was part of Mr Johnson's wider commitment to deliver a high-speed railway link across the north of England, which would cost about £39bn.

Mr Burnham said what he heard from the prime minister "certainly sounded good" but warned he heard "something very similar in almost the same spot from [then Chancellor] George Osborne five years ago and, in those five years, rail services here have gone in reverse".

The mayor added: "The focus on buses too and a London-style transport system for Greater Manchester sounded very good to me but we will have to see real action now to back up the prime minister's words.

"What about Liverpool, Sheffield, Newcastle? All of those places need a commitment.

"Commuting is a daily nightmare for people in large parts of the North - it costs £4 here for a single bus journey, £1.50 in London. How can that be right?"

National Infrastructure Commission chairman Sir John Armitt said: "The PM's decision today must be integrated with plans for HS2, and matched with devolved funding and powers for city leaders in the North - as set out in our National Infrastructure Assessment."

Mr Johnson wore a badge saying "Northern Powerhouse" during the speech.

Labour's shadow transport secretary Mr McDonald said the plans had been "announced time and time again by the Conservatives".

He added: "With Boris Johnson's staggering failure to build a bridge across the Thames and an estuary airport I'm not confident he'll be able to deliver better train services between Leeds and Manchester.

"What we really need is Labour's Crossrail for the North, from Liverpool to Hull and up to the North East to unleash the economic potential of the region.

"Just upgrading the rail between Leeds and Manchester - the same distance as the Central Line on the London Underground - won't achieve that."

Theresa May's government had said that it supported the idea of a new, fast rail route across the Pennines in principle - but it had not found the money to make it a reality.

The new rail line has been claimed to have a significant impact on journey times. Leeds to Manchester could be cut from about 50 minutes to less than 30 minutes.

Local authorities in the North have campaigned for extra funds for railways following years of investment in big transport projects in London such as Crossrail - and the rebuilding of several of the capital's rail stations.

Attention will now turn to the precise route and if the HS2 experience is anything to go by that's when the difficulties of building a railway become apparent.

Mr Johnson used the speech to state he is committed to "rebalance power, growth and productivity across the UK".

He also said "the unglamorous local services which people use every day" - such as buses - needed improving.

A survey by the Northern Powerhouse Partnership (NPP) found companies believed the upgraded network would boost productivity and investment.

NPP director Henri Murison said: "This is a seminal moment for the North - the entire Northern Powerhouse concept is all about connecting the cities and towns of the north to boost productivity."

Leeds City Council leader Judith Blake said: "Northern Powerhouse Rail is key to our vision for a modern, reliable transport network that delivers faster journey times, additional capacity and greater reliability and I hope the government will now work with us to accelerate delivery of this project."
