Passengers using the Metro trains across South Tyneside have been left waiting after a fault on one train, followed by an alert over a trespasser on the line.
Services between Bede and South Shields were halted during the last hour after a service heading to South Shields suffered a minor fault.

Metro bosses said it brought the running of the trains to a stop for up to 10 minutes, which then had a knock on affect to the network.
A further delay was then caused when a trespasser was spotted on the line, with Nexus and police carrying out checks to ensure there was no risk before trains started up again.
Both incidents happened between Tyne Dock and Chichester.
Meanwhile, crowds built up at South Shields as runners and spectators waited to catch Metros as people finished the half marathon.
A spokesman for Nexus, which operates the system, said: “Everybody we have is on the ground working with passengers, just to make sure that services are running smoothly.”
Nexus added up to 70 more trains are in service today, but agreed the additional demand on the Metro meant it was a “challenging day”.
More passengers had got on between Regents Park and Airport, which it has not expected.
Problems had also been experienced on the service at around 9.30am.
Sunderland AFC are playing against Spurs at the Stadium of Light, with the road closures between Newcastle and South Shields adding to problems on public transport and roads.
