Electrical arcing and fire on a Metro train and parting of the overhead line
at Walkergate station, Newcastle upon Tyne, on 11 August 2014
RAIB is investigating an accident which occurred on the Tyne and Wear Metro system at Walkergate station on Monday 11 August 2014.
At 18:56 hrs a two-car Metro train, travelling from South Shields to St James, arrived at Walkergate station. While standing in the station an electrical fault occurred to a line breaker mounted on the underside of the train, which produced some smoke. It also caused the circuit breakers at the sub-stations supplying the train with electricity, via the overhead line, to trip (open). About one minute later power was restored to the train. There followed a brief fire in the area of the initial electrical fault and further smoke. Shortly afterwards, the overhead line above the train parted and the flailing ends of the wire fell on the train roof and one then fell on to the platform, producing significant arcing and sparks for around 14 seconds. Fortunately, there was no-one on the platform at the time. However, there were at least 30 passengers on the train who self-evacuated on to the platform using the train doors’ emergency release handles. The fire service attended but the fire was no longer burning. No-one was reported to be injured in the accident and there was no significant damage to the interior of the train.

RAIB’s investigation will consider the sequence of events and factors that led to the accident, and identify any safety lessons. In particular, it will examine:
- the reasons for the electrical fault;
- the response of the staff involved, including the driver and controllers;
- the adequacy of the electrical protection arrangements; and
- actions taken since a previous accident of a similar type that occurred at South Gosforth in January 2013 (RAIB report 18/2013).
RAIB’s investigation is independent of any investigations by the safety authority. RAIB will publish its findings at the conclusion of the investigation. The report will be available on the RAIB’s website.
