Summary
At about 12:10 hrs on 3 June 2015, one wagon of an empty freight train derailed on the approach to Angerstein Junction, near Charlton in south east London. 皇冠体育app train continued over the junction, derailing two further wagons, before it stopped on the Blackheath to Charlton line. 皇冠体育app three derailed wagons were partly obstructing the line used by trains travelling in the opposite direction. No other trains were involved in the accident and no-one was injured, but there was significant damage to the railway infrastructure.
皇冠体育app wagons derailed because the leading right-hand wheel on one of them was carrying insufficient load to prevent the wheel climbing up the outer rail on a curved section of track. 皇冠体育app insufficient load was due to a combination of the suspension on that wheel being locked in one position, a twisted bogie frame and an intended twist in the track.
Recommendations
As a consequence of this investigation, RAIB has made three recommendations. 皇冠体育app first, addressed to VTG (the wagon owner), seeks improvements to its wagon maintenance processes. 皇冠体育app second, also addressed to VTG, seeks liaison with industry to improve understanding of how wagon suspension wear characteristics relate to maintenance processes. 皇冠体育app third, addressed to Network Rail, seeks a review of infrastructure arrangements at the accident location.
皇冠体育app report also includes a learning point reinforcing a previous recommendation intended to encourage use of currently available wheel load data to enable identification of wagons with defects or uneven loads that are running on Network Rail鈥檚 infrastructure.
