Passengers urged to check before travelling after landslip causes travel disruption between Aylesbury and Amersham

Region & Route:
North West & Central

Passengers travelling between London Marylebone and Aylesbury via Amersham are being urged to check their journeys while Network Rail carries out emergency repairs to the railway in Stoke Mandeville following a landslip.

On Tuesday (27 February) engineers from Network Rail closed one of the two tracks north of Stoke Mandeville station in Buckinghamshire after a track defect was identified. An inspection of the railway uncovered movement to the embankment which supports the track and means major repairs are needed before the line can be safely reopened to trains.

Approximately 5,000 tonnes of material has slipped along a 20 metre section of the railway embankment after persistent heavy rainfall weakened the earth beneath it.

Emergency repairs will involve installing 120 specialist nine-metre-long ‘soil nails’ into the railway embankment to stabilise the affected area and allow the track to be safely reopened to trains.

To complete the work Network Rail engineers need to close both tracks between Aylesbury and Amersham stations continuously from Friday 1 to Monday 4 March.

While the railway is closed, passengers are being advised about major changes to journeys between London Marylebone and Aylesbury via Amersham with buses replacing all trains between Amersham and Aylesbury Vale Parkway stations.

Network Rail engineers will make every effort to minimise disturbance to local residents and businesses during the repairs which are expected to cause some noise disruption. Staff will be informing neighbours about what to expect before the major engineering activity begins on Friday.

Adam Checkley, infrastructure director for Network Rail, said: “I’m really sorry to passengers and local people affected by the landslip at Stoke Mandeville which is causing disruption to trains between Aylesbury and London Marylebone via Amersham.

“Our major repairs will allow us to safely reopen the railway as quickly as possible and I want to urge passengers to check www.nationalrail.co.uk for the latest travel advice.”

Tony Baxter, operations director at Chiltern Railways, said: "We're sorry that customers between Aylesbury, Amersham and London Marylebone are being affected while Network Rail undertake urgent repairs to the railway.

"While the embankment is urgently repaired, no Chiltern services will run between London Marylebone and Aylesbury Vale Parkway via Amersham from Friday 1 March to Tuesday 5 March. 

"A rail replacement bus service will be in operation between Aylesbury Vale Parkway and Amersham while the line is closed. Ticket acceptance has been arranged for TfL services between Amersham and Baker Street. Customers at Aylesbury and Aylesbury Vale Parkway are still able to travel by rail to/from London via High Wycombe.

"Affected customers should check ahead before they travel. 

"We'd like to thank customers for their patience and understanding while we work to keep people moving and reopen the railway."

Before major repairs begin, the affected track will remain closed today and throughout Thursday 29 February, which means Chiltern Railways will continue to run a reduced timetable.
