Further engineering work is being carried out by Network Rail on the main line to London over the two bank holiday weekends to London.

There will be no through trains from East Anglia to Liverpool Street and Stratford on Sunday, May 6 – there will be a bus link from Ingatestone station to Newbury Park station on the Central Line. However the main line will be open on the Saturday and Bank Holiday Monday.

There will be no trains on the Felixstowe branch line from 7pm on the Saturday evening until Tuesday morning, May 8, and there will be a bus replacement between Ipswich and Woodbridge stations on Sunday and Bank Holiday Monday.

Over the late bank holiday weekend – May 26-28 – there will be no through trains to London, with the Ingatestone to Newbury Park bus link in place throughout.

Network Rail engineers are hoping to replace 3km of overhead wire in the Ilford area during the weekend closure.

And there will be no trains on the Felixstowe branch on the Sunday and Bank Holiday Monday as work continues to upgrade the rail link to the port.

Meliha Duymaz, Network Rail’s route managing director for Anglia, said: “We are continuing our work to transform rail services for passengers in Norfolk, Suffolk and Essex as part of our Railway Upgrade Plan.

“While I understand that closing the line is inconvenient, it’s vital that we get these chunks of time in order to carry out these important upgrades. I’d like to thank passengers for their patience while we carry out this work.”

Jamie Burles, Greater Anglia Managing Director, said: “We know people would rather stay on the train the whole way, but we have arranged over 400 buses during the two bank holiday weekends to make sure that customers can still complete their journeys.

“We’ll also have extra staff on hand help make the journey as easy as possible for passengers.”

Greater Anglia is installing free wifi in all its electric trains throughout the region, both Intercity sets and suburban units – also providing NOW TV and Hayu TV shows for passengers.

The £4.5m programme will upgrade existing trains before they are replaced by modern units which will have wifi installed when they start to come into service next year.
