The way that England's railway network is run is set to be overhauled under plans outlined by Transport Secretary Chris Grayling.

He wants each rail franchise to be run by joint management teams, including representatives from both the train operating company and Network Rail.

Mr Grayling said: "I intend to start bringing back together the operation of track and train on our railways."

The changes will start when each franchise is renewed in the future.

The minister said he wanted the changes to improve services for passengers, who are travelling on an increasingly crowded and expensive network.

"We need to change the relationship between the tracks and the trains on the railway," Mr Grayling said.

"In my experience passengers don't understand the division between the two.

"They just want someone to be in charge. They want their train to work. I agree with them," he added.

Each franchise will be run by one joint team, but the franchise owners and Network Rail will continue to exist separately.

The first new joint management teams will come into operation when the South Eastern and the East Midlands franchises are re-let in 2018.

Network Rail's chief executive, Mark Carne, said the new plan would "bring more joined-up working within the industry".

Lianna Etkind, of the Campaign for Better Transport, gave the proposal a cautious welcome.

"Rail passengers are not interested in the finer details of the management of the railways, they just want trains that are punctual, safe and reliable and don't cost the earth to use," she said.

"We hope that these reforms will work, but ultimately they will be judged on whether they actually deliver better and cheaper services for passengers."

The establishment of railway franchises, separate from the network infrastructure, goes back to the privatisation of British Rail in 1993 by John Major's Conservative government.

This separation, which is still in force, is held by some critics to be a significant source of delays to management decisions, repairs and train services.

Rail privatisation was partly reversed in 2002 when the previous infrastructure owner, the privately-owned Railtrack, was taken over by the government-controlled Network Rail in the wake of the Hatfield rail crash.

'Further complexity'

Mick Cash, general secretary of the RMT rail union, told the BBC the proposed changes were "a slippery slope to privatisation and the break-up of Network Rail" and that the union was "deeply concerned".

"We don't want to go back to the Railtrack days," he said. "It's quite clear they want to break up Network Rail, they want to privatise the rail infrastructure.

"We don't want to go back to the days of [rail disasters] Hatfield and Potters Bar - that's what happens when you get the private sector in charge of our infrastructure."

Shadow transport secretary Andy McDonald told the BBC that what the government "appears to be contemplating is yet further complexity, yet further fragmentation, and more opportunities for private entities to extract value out of our railway system".

He said that franchises should be brought back under public ownership as they come to be renewed.

However, Mr Grayling said the changes were "not about privatising Network Rail, it's not about handing over control of the track to train operating companies, it's about forging partnership alliances between the two".

Richard Westcott, BBC transport correspondent

I have never met anyone, no matter what their politics, who thinks it was a good idea to have one company running the trains and another running the track they run on.

But that's what they decided to do when they privatised the network 20 or so years ago.

I've heard of crazy situations, where train companies made money out of Network Rail when it overran on engineering work (they had to pay a fine). Then the firm would make extra money running the replacement bus service too.

Different companies, with different priorities.

Now Chris Grayling has become the latest transport secretary to try to get Network Rail working as one with private companies to fix the problems together, rather than arguing about whose fault it is.

They are already trying something like it across Scotland and with South West Trains.

As for getting one private company running everything on a future Cambridge to Oxford line, some fear it's an attempt to privatise rail repairs, which ended disastrously under Railtrack.

Speaking to the transport secretary, though, he told me that he had no intention of making radical changes across the network, or breaking up Network Rail. He just wants the public and private sector, train and tracks, to work together - not against - each other.

Varsity line

The new management approach may also be applied to the running of the revived "Varsity Line" between Oxford and Cambridge.

The recent Autumn Statement confirmed that the line, which was closed in the 1960s, should be rebuilt and reopened.

The line will be designed, constructed and run by a new body called East West Rail, which will be separate from Network Rail.

Mr Grayling said that, on this line, the track would be publicly owned but run by a private company, and would "provide a degree of comparison with Network Rail to say 'can we build lines quicker and cheaper than we are at the moment?'."
