Keith Sibley, Crossrail Area Director West said: said: “Tunnelling has now recommenced with Phyllis progressing from Paddington towards Bond Street.

“Ada will recommence tunnelling next week as will the direct loading of rail freight wagons ahead of transport to Northfleet.”

The TBM restarted at 10.30 on Monday after work was suspended earlier this month following the collapse of a spoil hopper.

The collapse caused a backlog of tunnel spoil which led to the suspension of boring.

A Crossrail spokesman said: “Stockpile levels at Royal Oak have now been sufficiently reduced and tunnelling can now recommence.

“Lorries have been used to reduce the stockpile at Royal Oak. Excavated material from tunnelling will be stockpiled at Royal Oak this week ahead of removal by lorry.

“Once this stockpile has been fully depleted, the use of lorries to transport excavated material from the site will discontinue.”
