This today from Transport For London:
"Tube service update: 19 July 2005
The Northern, Victoria and Metropolitan lines are now stopping at King's Cross St. Pancras.
Repairs have started at Aldgate and we expect to resume a full Metropolitan line service to Aldgate and a special Hammersmith and City service between Baker St and Barking by Monday 25 July.
Police work continues at Edgware Road. However, we hope to restore a full service on the Circle and Hammersmith & City lines (and the District line to Edgware Road) within two weeks (2 August).
Police remain on site at King's Cross/Russell Square and Piccadilly line services remain suspended between Hyde Park Corner and Arnos Grove.
Thank you for your continued patience as we work to resume full services"
