Rail Accident Investigation Branch
At about 07:17 hrs on 30 September 2022, a tram derailed at a set of points located just south of Highbury Vale tram stop on the Nottingham Express Transit (NET) system. Although the tram was in service, there were no passengers aboard it when the accident occurred.
The tram, which was travelling north from David Lane tram stop, was intended to take the left-hand route at the points, towards Phoenix Park. However, as the tram reached the toe of the switches, the points involved moved to a mid-position, causing the tram to derail. The tram was moving at approximately 11 km/h at the time of the derailment. No injuries resulted from the accident, although some damage was caused to tramway infrastructure and to the tram itself.
We have undertaken a preliminary examination into the circumstances surrounding this incident. Having assessed the evidence which has been gathered to date, we have decided to publish a safety digest.
The safety digest will be made available on o
