ENGINEERS WERE this week working with anti-terrorist police to decide how to remove the bomb damaged carriage on the Piccadilly Line train following the terrorist attacks on 7 July.
The train is one of three hit by terrorist bomb blasts in which 42 people died.
The bomb damaged train near Aldgate Underground station was removed last week.
The Edgware Road train was due to be removed as NCE went to press.
On the Piccadilly Line, contractors working in a 3.66m diameter tunnel, 30m below ground, have removed four carriages of the six car train.
This leaves the front carriage and the adjoining carriage where the bomb exploded.
Piccadilly Line maintenance contractor Tube Lines is to drag away the relatively undamaged fifth carriage using a locomotive.
'But we can't drag the [bomb damaged car] because it doesn't fi down the tunnel anymore. If we did it would damage the tunnel, ' said Tube Lines operations director Stephen Peat.
He added that the damaged car will have to be cut up before removal. It will then be reconstructed for further forensic examination.
Tube Lines manages the Emergency Response Unit (ERU) which has been working around the clock on the Tube bomb sites since 7 July (News last week). It has 300 people working to restore the lines.
Just a few hours after the explosion, it sent tunnel experts down to the Piccadilly Line tunnel to assess damage.
'They bravely inspected the site to check it was safe for the police to work in. At that time conditions were very diffi cult and the police were still looking for more devices, ' said Peat.
'We have no idea how the cables and signalling have been affected, but we think the tunnel section is OK.' He added that track will be scanned with ultrasonic equipment and defective rails replaced.
Tube Lines also hopes to bring forward track replacement and renewals work on the line while it is closed.
