People using the Metro service face delays tonight after an overhead cable reportedly came down on one of the trains.
At just after two this afternoon, an overhead line failed above a train between South Gosforth and Longbenton stations.
Around 50 passengers were taken across the track to another station while a second train was reversed to Longbenton to allow passengers to get off.
Trains were suspended between South Gosforth and Airport and a replacement bus service put in place.
A Metro spokesman has apologised for the inconvenience and said the incident was being investigated.
