Network Rail say the railway line between Dover Priory and Folkestone Central in Kent is currently closed due to severe cracks appearing in the sea wall at Dover.
High tides damaged the wall that protects the railway near Dover Harbour - the cracks on the wall were discovered on Christmas Eve.
Rail services between Dover and Folkestone are likely to remain closed for more than a month after part of a sea wall collapsed due to a high tide.
The cracks were discovered on Christmas Eve. Severe damage has been caused to a number of sections of the track. There are also sink holes two or three metres deep along the length of the wall.
Engineers have been assessing the damage, and work to repair 250 metres of track will start shortly. The sea wall will also need to be rebuilt.
It means a bus replacement service is running on Southeastern Trains between Dover Priory and Folkestone Central. Network Rail say it's not yet clear when the railway will re open.
