A major overhaul to the escalators is taking place at London Kings Cross. This means the escalator between the mezzanine footbridge and platform 8 are out of order until 6 February.
There is still step-free access available between the station concourse and all platforms.
Trains between Peterborough and Stevenage may be cancelled, delayed by up to 60 minutes or revised. More details can be found in Status and Disruptions.
