London railway sinkhole repaired


A sinkhole that closed four rail lines between East Croydon and London Bridge has been repaired.

Network Rail has completed work on a sinkhole that has caused disruption at London Bridge station since Monday (18 July).

London Overground services between West Croydon/Crystal Palace and New Cross Gate were also disrupted. 

The sinkhole opened up after a sewer collapsed 6m beneath the tracks. Thames Water sealed and diverted the sewer to allow repairs to take place.

Dry concrete was placed into the hole to form a base for wet concrete to be poured on top. Engineers then added 50t of ballast.
