Following the announcement from the Associated Society of Locomotive Engineers and Firemen (ASLEF), strike action is planned from December 1 to 9.

Greater Anglia services

Greater Anglia services will be impacted from December 1 to 9, with many service alterations and a strike day.

Service alterations from Friday 1 to Monday 4 will result in some cancelled services due to action called by the ASLEF union.

All trains on Sunday December 3 from Wickford to Southminster have been cancelled, as well as Manningtree to Harwich, Ipswich to Felixtowe, and Marks Tey to Sudbury.

Tuesday 5 is a strike day, resulting in no services running on regional lines.

Several other Greater Anglia lines will be running on a reduced schedule. 

On Wednesday 6 all trains will start later than usual, and Thursday 7 to Saturday 9 there may be some cancelled services.

Mark Goodall, CrossCountry's Service Delivery Director, said: " We're sorry to customers impacted by this latest round of industrial action. While we're working hard to run as many services as possible over these days, there is likely to be significant disruption for people planning to travel – especially on Sunday 3 December.

"I'd ask customers to check their whole journey before setting off, especially if travelling later in the day. Customers can visit the CrossCountry website or National Rail Enquiries for the latest travel information."
