Strikes and an overtime ban by members of the ASLEF union will severely disrupt Greater Anglia services from Monday, 29 January to Tuesday, 6 February.

From Monday, 29 January to Thursday, 1 February and Saturday, 3 to Tuesday, 6 February, most services will operate normally on all Greater Anglia routes, but there will be some planned cancellations.

On Friday, 2 February, there will be a very limited train service, and only on the following five routes. Those routes and the first and last trains are:

• Norwich – London Liverpool Street: hourly
• Norwich, 08.00 – 19.00
• London Liverpool Street, 10.30 – 21.30

Great Northern and Thameslink will be operating some services between Cambridge and London Kings Cross on Friday, 2 September.

Engineering Work will also affect Greater Anglia services on Saturday, 3 February and Sunday, 4 February, with trains replaced by a rail replacement bus service.

Trains from London Liverpool Street to Cambridge will start/terminate at Audley End with rail replacement bus services to/from Cambridge North, from where a frequent train service will operate to Cambridge.

Stansted Airport to Norwich services will only run between Cambridge and Norwich.

There will be no trains between London Liverpool Street and Shenfield, Southend Victoria and Southminster. Rail replacement buses will operate between Southend Victoria and Newbury Park underground station, calling at all stations between Southend Victoria and Shenfield. At Newbury Park passengers can transfer to Central Line underground services to Stratford and London Liverpool Street.
Rail replacement buses will operate between Wickford and Southminster.

There will be no trains between London Liverpool Street and Shenfield all day on Sunday. Trains from Norwich, Ipswich, Clacton and Colchester will terminate at Shenfield.

Rail replacement buses will operate between Ingatestone to Newbury Park underground station where passengers can transfer to Central Line underground services to Stratford and London Liverpool Street.

A shuttle service will operate between Witham and Braintree, Marks Tey and Sudbury, Thorpe-le-Soken and Walton-on-the-Naze, and between Manningtree and Harwich Town.

From 23:15 until the close of service on Sunday, West Anglia and Stansted Express services will be diverted between London Liverpool Street and Cheshunt, serving Seven Sisters instead of Tottenham Hale with extended journey times.

Jamie Burles, Greater Anglia’s managing director, said: “Unfortunately on the 2 February, no services will run at all on most Greater Anglia routes, with just an hourly service during normal operating hours on the Stansted Airport to London route and an hourly service for limited hours on the Norwich to London, Colchester to London and Southend Victoria to London routes, plus a few services between Cambridge and London Liverpool Street.

“On the days affected by action short of a strike, the vast majority of services will be running as normal, but there will be some alterations and cancellations across our network.

“Please note that an extensive engineering works programme will also take place on Saturday 3 February and Sunday 4 February. This work is extremely important to help maintain the safe and reliable running of the railway and make it fit for the future. A rail replacement service will run while the work takes place.

“We are sorry for any inconvenience caused by these service alterations and advise customers to plan ahead and check before they travel.”
