The government says its running of the franchise was always a temporary measure. Campaigners claim it has been successful, both financially and in terms of customer satisfaction, so should remain in public ownership.
The Government has published a shortlist of three bidders under plans to re-privatise the East Coast mainline - which runs from London through East Anglia, Yorkshire and the North East to Edinburgh - sparking a row over whether the rail franchise should remain publicly-run.
Some of the biggest transport firms, already running rail routes across the UK, including the First Group, Stagecoach, Virgin, Keolis and Eurostar, are on the list of preferred bidders for the 393-mile route.
Unions and other groups have been campaigning for months to halt re-privatisation of the franchise, which has been publicly-run since 2009. One union official accused the Government of "economic vandalism".
The three shortlisted biddes are East Coast Trains Ltd (First Group plc); Keolis/Eurostar East Coast Limited (Keolis (UK) Limited and Eurostar International Limited); and Inter City Railways Limited (Stagecoach Transport Holdings Limited and Virgin Holdings Limited).
The new franchise will start early next year.

The nationalised railway company operating the East Coast main line , which runs through the Calendar region, has returned £208.7 million to taxpayers as revenues soared, fuelling the debate over plans to return it to private hands.
Directly Operated Railways (DOR), which took over the running of the key London-Scotland route four years ago, saw the figure increase by 6.6% in the year to the end of March.
Turnover increased 4.2% to £693.8 million while total sales were up by 4.2%, including ticket revenues, as well as catering and car parks.
The figures reignited the debate about the Government's intention to re-privatise the line - with a new franchise expected to start in February 2015.
Labour and rail unions have questioned the need for re-privatisation, arguing that DOR is returning a high level of money to the Department of Transport and receives a lower taxpayer subsidy than others.
Last week it was announced that Channel Tunnel high-speed company Eurostar was bidding to operate the route jointly with French firm Keolis. The successful bidder is expected to be announced in February 2015.
The RMT union says it's 'stepping up' its fight to prevent the East Coast Main Line being returned to the private sector.
