At around 06:00 hrs on Thursday 23 January 2020, a freight train travelling from Barking to Calvert derailed on a bridge near Wanstead Park station. The train, comprising a class 66 locomotive and 22 wagons carrying construction soil, then travelled about 2.5 miles (4 km) before the braking system indicated a possible problem to the driver. The train was stopped between Leyton Midland Road and Walthamstow Queens Road stations with one wheelset on the 16th wagon derailed. The derailment resulted in extensive damage to the track, other railway infrastructure and the wagon.
