Engineering work is taking place between Gidea Park and Shenfield, closing 2 out of 4 lines overnight from 21:25 from Monday to Thursday.
As a result, most trains between London Liverpool Street and Shenfield will have extended journey times of around 15 minutes as they travel slowly past the work site.
Additionally, the 21:20 Southend Victoria to London Liverpool Street and the 21:35 London Liverpool Street to Southend Victoria will be cancelled.
