This weekend, upgrades will be underway on a section of the Chiltern Main Line, resulting in a closure between London Marylebone station and Gerrards Cross, and between Bicester North station and Gerrards Cross.

Those wanting to travel to London Marylebone are being advised to plan ahead for the 28th and 29th March.

Sections of track will be upgraded during the work as a continuation of the improvement work in West Ruislip earlier in the month.

Around 370 yards of track will be renewed, along with sleepers and ballast, and 470 yards of re-railing will be carried out.

Additionally, drainage work will be carried out between Dollis Hill and Neasden and at Walm Lane, which will also affect the London Underground Metropolitan line.

Journeys can be checked online before travelling.

“These are the kinds of vital upgrades which will allow the railway to continue running reliably for passengers for decades to come.

“We would like to thank passengers for their patience while the work takes place and urge them to check with National Rail Enquiries ahead of travelling on the weekend of 28 and 29 March.”
