Sadiq Khan, in once again calling for TfL to take over the day-to-day running of Southern Rail, is casting himself as commuter’s knight in shining armour.

The reality however is that TfL running Southern’s disastrous services would be a monumental mistake, and a far costlier and riskier endeavour than using contractors, as it already does with other services like London Overground.

Southern needs reform from the ground up –something TfL will not be able to deliver with its existing team. The Mayor needs to stop making grand gestures of heroism that would do little to change things and instead come up with a sensible solution to end the misery for commuters.
