Engineering work is taking place between Alexandra Palace and Hatfield between 00:10 and 05:20 on Tuesday to Friday mornings, closing some lines.

As a result, no trains will call at Welham Green during this time. Trains running Southbound (towards London) will not be able to call at Hatfield. Replacement buses will run between Potters Bar and Welwyn Garden City, serving these stations.

Additionally, a reduced train service will run at Harringay, Hornsey and Alexandra Palace.
