A government review is considering handing over greater control in an attempt to improve performance

Network Rail could be given new powers over trains in the biggest overhaul of the railways for 25 years.

The Times has learnt that a government review is considering handing greater control to Network Rail, which currently operates the tracks, in an attempt to improve performance.

The government-owned infrastructure group would get the power to specify and award contracts to private train operators to run passenger services, bringing the operation of the tracks and trains closer together.

Rail industry sources said that the initiative was being closely considered by Keith Williams, the former chief executive of British Airways, who is leading the review.

The plan will prove controversial after criticism of Network Rail’s performance, including last year’s chaotic introduction of new timetables and delays
