A section of railway track between Dorking and Horsham has had to be closed due to a landslip.
Network Rail have confirmed there will be no trains running between the two points until at least 30th January, but a rail replacement bus service is in operation.
Southern rail have described the landslip as substantial which has severely affected the track due to earth which has shifted.
Passengers are being advised to check Southern or National Rail websites before they make any journeys.
