I just read this from the tube's website on the ask tube section
"Question


When will the Tubes be returning to normal after the events of 7 July?


Answer


We will not be in a position to add to the current level of service on
the Metropolitan, Circle, District and Hammersmith & City lines for a
number of days.

The service on the Piccadilly line will remain suspended between Arnos
Grove and Hyde Park Corner for the foreseeable future.

Following agreement with the Police, the Victoria line is now stopping
at King's Cross/St Pancras. The Northern line will start stopping at
King's Cross/St Pancras again from Monday 17 July."

Why is so much of the Piccadilly line closed? I'd have thought they could
run trains to within a station or so either side of the blockage. Or does
the damage to the cable between KX and RS have a knock-on effect on *all*
of
the section north of KX? Is it a matter of where there are crossovers to
allow southbound trains to turn back at (say) KX to return north? You'd
think that at least Arnos Grove to Finsbury Park could be run, so as to
feed
outlying passengers into the Victoria line and the NR lines into KX and
Moorgate.


Times may well have changed and this may not be an issue now, but one other
potential problem is that this also severs the Northern Line from the rest
of the underground network? The only connection between the Northern and the
rest of the underground is provided by the Kings Cross loop which is
(presumably) out of use for the time that the Piccadilly is split in two
like this? This was probably more important when Acton was the Central Works
but it also prevents engineers trains etc from reaching the Northern, which
could make track maintenance etc more difficult.
