CITY RAIL LINK SQUEEZES INTO OLD TUNNEL

The article describes the removal of extensive sections of brick invert along the London city line tunnel between Kings Cross and Farrington to increase clearances for operating British Rail electric services into Moorgate. The extreme caution exercised in the removal of about 200 separate breakouts which were made at six locations is emphasized. A Krupp 200 breaker was used for the work, the brickwork being replaced by reinforced concrete. Reference is made to traffic control during concreting operations. Around 150 cubic metres of pumped ready mixed concrete was moved up to 200 metres each day. A Pact system paver will be used to slipform the concrete track bases.
