Major March Closures Announced Across London Overground

Commuters and weekend travellers across east and north London face a string of service suspensions this month, with Transport for London confirming a series of planned closures affecting the Overground network and parts of the Elizabeth line.
The disruption, linked to ongoing engineering and track renewal work being carried out by both TfL and Network Rail, will run across multiple weekends in March — with some routes facing complete shutdowns and others running at significantly reduced frequency.
Which lines are affected and when?
The Liberty line, which runs between Romford and Upminster, faces the most repeated disruption. It will be closed on six separate days: March 8, 14, 15, 22, 28 and 29.
The Weaver line faces a more varied picture. On March 14 and 15, trains will run but at reduced frequency from 09:50 onwards — two trains per hour to Chingford and one each to Enfield Town and Cheshunt from London Fields. Before 09:50 on both days, replacement buses will serve routes between Seven Sisters, Hackney Downs, Enfield Town, Cheshunt and Chingford.
From the weekend of March 21–22 through to March 28–29, the situation becomes more severe. There will be no Weaver line services at all between London Liverpool Street and Enfield Town, Cheshunt or Chingford across all four days. Rail replacement buses will again be in operation between Seven Sisters and Enfield Town or Cheshunt, and separately between Hackney Downs and Chingford.
The most disruptive single day falls on Sunday, March 22, when closures extend beyond the Overground. On that date, there will be no Elizabeth line services between Paddington and Abbey Wood, or between Whitechapel and Shenfield — in addition to the Weaver and Liberty line shutdowns already planned.
The Mildmay line is affected on one day only: Sunday, March 8, when it will be closed between Camden Road and Stratford.
What should passengers do?
TfL is advising all passengers to check their journeys before travelling, either through the TfL Go app or at TfL.gov.uk. Customers are also being asked to allow extra time where rail replacements are in use, as bus alternatives typically take longer than train services on the same routes.
The works form part of a broader reliability and maintenance programme. Network Rail is handling improvement works in east London, while TfL is delivering track renewals on the central section of the Elizabeth line.​​​​​​​​​​​​​​​​
