Commuters beware that trains from Welwyn Garden City and Hatfield are being disrupted this morning.

A speed restriction has been put in place over a defective track by new Barnet, and so services are travelling slower than usual.

Great Northern services between Stevenage and Finsbury Park may be delayed by 10 minutes until about 8.30am.

This will affect Hatfield, Welwyn Garden City, and Welwyn North stations.
