Network Rail has issued a video update about the landslip at the Yarnton overbridge near Oxford, pictured, which has forced a temporary closure of the Cotswold Line.
Its engineers are working with contractor Balfour Beatty to install a retaining wall to support the unstable embankment. This will allow train services and road traffic to resume while permanent repairs are completed.
The aim is to allow train services to start running again between Oxford and Charlbury from Wednesday next week, February 22.
Until then trains will operate between Worcester and Hanborough, with rail replacement buses linking Hanborough and Oxford stations.
An additional challenge facing the engineers is a gas main buried beneath the road surface, which has been exposed by the collapse of part of the embankment.
A retaining wall at the bridge collapsed last Friday evening, with debris blocking the track.
