Hundreds of passengers are queuing in Newcastle city centre to catch buses home after Metro services were suspended.
Sections of the network ground to a halt after it's thought a train got caught up in overhead power lines sagging in the hot weather.
Long queues have formed at bus stops across Tyneside with some passengers telling Tyne Tees they have been waiting more than two hours.
It is not yet known when the network will be running at full capacity again.
