Metro bosses have said they plan to run a normal service on the system on Monday - after a day of chaos today.
No trains ran for much of today after a problem at an electrical sub station meant system owners Nexus were unable to get the trams out of the depot at South Gosforth, Newcastle.
A limited service was provided late in the afternoon.
At 10.30pm a statement from Nexus said: We expect to run a full service tomorrow (Monday).
“Please check for updates.Thanks for your patience.”
