Ливерпуль-стрит
On 3 May 2008, a 1,300-tonne Warren truss bridge (GE19 bridge) spanning Great Eastern Main Line tracks out of Liverpool Street station was put into place. Although the bridge launch was successful, on 28 May the bridge dropped 200 mm onto its permanent supports as it was being jacked down. Debris fell onto the tracks, forcing the suspension of services in and out of Liverpool Street station until the following day and causing major disruption to commuters. The problem was traced to errors made by the sub-contractors.
