Elizabeth line passengers are being urged to plan ahead as major engineering works will shut down most of the route over the weekend of 28 and 29 November.

The closures mean passengers travelling across London and to Heathrow Airport will need to find alternative routes or allow extra time for their journeys.

A limited service will continue between Maidenhead and Reading, with two trains running per hour in each direction.

Transport for London (TfL) said the weekend closure is needed to carry out essential maintenance and engineering work to keep the railway running safely and reliably.

The work will include replacing sections of track and crossings, as well as maintaining overhead electrical equipment.

Rail replacement buses will run on several affected routes, including Stratford to Romford, Shenfield to Chadwell Heath and Newbury Park, Ealing Broadway to Slough, and Slough to Maidenhead.

Passengers are also being advised to use alternative Tube, National Rail and local bus services where possible.

Trish Ashton, TfL's Director of Rail, said: "We understand that these closures can impact customers’ journeys and would like to thank them for their patience while this essential work takes place.

“The work we’re carrying out is essential to maintaining the safety and reliability of the Elizabeth line for the millions of customers who rely it on every year.

"We encourage customers to plan ahead, allow extra time for their journeys and check before they travel on TfL's Journey Planner or the TfL Go app. Rail replacement buses and alternative travel options will be available throughout the closure."

The Elizabeth line is the UK's busiest railway service, carrying passengers across London and connecting the capital with destinations in Essex, Berkshire and Heathrow Airport.

TfL is urging passengers to check their journeys before setting off using its Journey Planner or TfL Go app, with disruption expected throughout both days.
