Tyne and Wear Metro Services have announced a system-wide service suspension from 5.15pm today until 8.15am tomorrow.
Metro tickets will be accepted on all local bus services during this time.
Customers are advised to seek alternative arrangements if they need to travel at the times affected, including making journeys later on Sunday morning.
Nexus, the public body which operates Metro, has apologised for the disruption and the inconvenience it will cause, which is the result of an industrial relations matter involving Metro’s Control Centre employees.
Metro services will start running off after 4pm on Saturday although the majority of stations will see their last trains between 5pm and 6pm in the evening.
On Sunday morning the service will build up from 8am with a normal timetable from 9am.
John Alexander, Metro operations director, said: “We are forced to suspend the Metro service across the system on Saturday evening and early Sunday morning due to an industrial relations matter affecting our Control Centre. I am sorry for the inconvenience this will cause for many people."
