Trains are running again on the full length of the London Overground route between Gospel Oak and Barking, after 4km of track was ripped up by a derailed freight wagon. The derailment occurred early in the morning of 23 January, when one pair of wheels on a freight train travelling from Barking to Calvert became derailed on a bridge near Wanstead Park station. The train had travelled another 4km before the driver was alerted, and by then the derailed wheels had caused extensive damage to the track.
