A spokesman has confirmed that the Tyne and Wear Metro line between Haymarket, Regent Centre and Four Lane Ends did not reopen as planned this morning because of signal faults detected by tests overnight.
The rest of the line is running normally, including between Regent Centre and Newcastle Airport. The spokesman said there was no problem with the upgraded track. The issues should be resolved soon.
