PASSENGERS are being warned to expect delays to train services until at least 5pm after weekend engineering work over-ran.

Some lines are blocked on the main line between Gidea Park and Shenfield due to the problem.

Services to and from London and Southend Victoria, Colchester, Clacton and Braintree are all affected.

A Greater Anglia spokesman said: "Due to over-running engineering works between Gidea Park and Shenfield some lines are blocked. 

"Train services running through these stations may be cancelled or revised. Disruption is expected until 5pm."
