Engineering work is taking place between Cambridge Heath and Cheshunt, closing some lines.

From 23:35 on Monday to Thursday evenings until approximately 05:15 on Tuesday to Friday mornings, Greater Anglia and Stansted Express trains that usually run via Seven Sisters will be diverted to run via Tottenham Hale instead.

Stations on the Tottenham Hale line are only a short distance from those on the Seven Sisters line. You can view maps that show routes between these stations on the Greater Anglia website.
