ノーザン線
Access to the Northern line platforms was indirect, its escalators connecting with the Piccadilly line. As the traffic from all three tube lines would have overcrowded the Victoria line escalators, Northern line trains did not stop at King's Cross until repairs were complete. The nearly life-expired Northern line escalators were replaced as well and the Northern line station reopened, completing the return to normal operation, on 5 March 1989.
