£23M landslip work for Settle-Carlisle line

Eden Brows 2by3

Network Rail expects landslip repairs on the Settle-Carlisle line will be completed in late March 2017. 

A 500,000t landslip is to be overcome with a tunnel-like structure constructed from concrete and steel that will sit beneath the Settle-Carlisle railway line. 

Located 70m above the River Eden, two rows formed from high-strength piles will sit in Eden gorge’s sloping bedrock.

The piles will form corridor on which a 1.5m thick, 100m long concrete slab will be placed to provide a solid base for the tracks.

The project is budgeted at £23M and was selected from six different proposals.

In February, the landslip caused the railway to fall 1.5m below its usual level. The line has been closed since the slip.

A £5M earthworks project will be undertaken during the work to protect the river bank below. Rock armour and drainage systems will be combined with tree planting to protect the land from erosion and further landslips.

“The tunnel-like structure we’re building will safeguard this section of railway for generations to come. If the land gives way again, the railway will not,” said Martin Frobisher, managing director for Network Rail’s London North Western route.

The Eden Brows repair programme:

  1. Access ramps built to bring piling rigs on to the site
  2. Trains begin removing spoil from site as the old track bed is removed
  3. Temporary piles installed to stabilise the piling rigs
  4. First row of contiguous piles, near the brow of the slope, installed
  5. Second row of contiguous piles, on the side closest to the river, installed
  6. Concrete slab laid over the top of piles, forming a tunnel-like structure
  7. Track with aggregate and ballast beneath laid on top of the concrete slab
  8. Driver training before reopening of the closed section of line
  9. Any follow-up works required in order to restore full line speed of 60mph.
