Farnham and Alton railway landslip work starts
A section of the Farnham to Alton rail line hit by a landslip is set to remain closed for at least three weeks.
The track has been shut since the embankment became unstable following heavy rain last week.
Network Rail said the site was "continuing to deteriorate" and work was under way to stabilise the ground.
South West Trains said replacement buses would operate between Farnham, Bentley and Alton stations until at least 9 May.
Engineers are working at the site of the landslip in Wrecclesham, 1.3 miles (2.1km) from Farnham.
