Railway engineers have been carrying out trackside repairs to prevent a large bank slipping on to the main Brighton Line.

There was evidence a large section of bank near Earlswood, Surrey, at Stokes Nest Junction, was in danger of slipping on to the track, taking trees and shrubs with it.

The danger was first spotted in the early hours of Sunday and engineers have been mounting a stabilisation programme, which involves building a new retaining wall close to the track.

It is hoped the work would be completed early today.

Trains have been diverted via Redhill while the emergency work takes place, causing delays of up to half-an-hour between London and the Sussex Coast.
