Work was forging ahead last month on a 650m length of cut and cover tunnel and retained cutting linking the cross-London Thameslink line to the East Coast Main Line. The work follows on from the newly completed Thameslink 2000 station box at London St Pancras.

The connection is being carried out by Channel Tunnel Rail Link joint venture contractor Kier-Nuttall for Network Rail.

Sheet piled retaining walls are being installed to a depth of 17m through made ground overlying London Clay. To minimise the amount of hammering, ground is being loosened by preaugering ahead of piling. The tunnel and cutting are part of the 'last 5% of civil work remaining to be done' on CTRL contract 103, said Kier Nuttall project director Russell Laing.

Other civils work to be wrapped up includes landscaping of spoil from tunnelling and piling, and an access road to the industrial estate at the centre of the spaghetti of railway lines.
