Passengers travelling to and from London Liverpool Street this Easter are reminded to check routes as Network Rail engineers continue to upgrade the line.

Work over Easter will follow the weekend closures that have taken place since early February.

Network Rail Anglia’s project manager, Gary Desmond, talks about the upgrades he and his team will be carrying out over the Easter period in a short video.

The work includes renewing the overhead lines at Brentwood so that they don’t sag in the heat of summer, replacing track at Maryland, Forest Gate and Shenfield and track and overhead line improvements at Shenfield to prepare for Crossrail.

Richard Schofield, route managing director, said: “The orange army has been out every weekend since the beginning of February to improve the railway to provide more reliable journeys for passengers.

“This work will continue over the Easter weekend and I would like to thank passengers for their patience while we carry out this essential work to upgrade the railway in Essex.”

On Good Friday, a revised Sunday-style service will operate on mainline routes, with additional early morning trains, to allow for engineering work to take place.

But from Saturday, all services will be revised.

Rail replacement bus services will operate between Ingatestone, Wickford and Newbury Park, where customers are asked to use London Underground Central Line services in and out of London.
