Press Release from the UK Rail Accident Investigation Branch: Derailment at Liverpool Street Station in London, 23 January 2013
Several wheels of the 10:00 hrs London to Norwich service derailed as the train left Liverpool Street station at its scheduled time on 23 January 2013. The train comprised nine coaches with a driving cab in the leading coach and a class 90 locomotive at the rear of the train. The train was travelling at about 15 mph (24 km/hr) when several wheels on the third and fourth coaches derailed about 180 metres beyond the end of the platforms. The track layout and the continued forward movement of the train meant that all the wheels had climbed back onto the rails within about 35 metres.
Noises caused by the derailment were reported and the train was stopped and inspected. A second inspection at Norwich revealed wheel damage consistent with a derailment and the train was withdrawn from service. The line concerned had been closed to passenger traffic at 10:05 hrs and track damage caused by a derailment was found at around 12:45 hrs.
The RAIB’s investigation will examine the sequence of events leading up to the accident and the cause of the derailment. This will include consideration of the design, maintenance and condition of both the track and the derailed coaches.
The RAIB’s investigation is independent of any investigation by the safety authority (the Office of Railway Regulation).
The RAIB will publish its findings, including any recommendations to improve safety, at the conclusion of its investigation. This report will be available on the RAIB website.
