Rail services have resumed fully in both directions on the Sunderland to Newcastle line after a broken down Metro train was removed.
Passengers experienced up to around three hours of delays after a compressor failure meant the train's doors could not open.
Northern and Metro services along the line were affected in both directions after the service limped to a halt between Fellgate and Brockley Whins stations at 12.23pm.
A replacement taxi service operated between Heworth and Brockley Whins stations while trains continued to operate between Brockley Whins and Sunderland's South Hylton station.
Metro operator Nexus tweeted just after 3.30pm: "Service has now resumed between Pelaw and Brockley Whins in both directions. We are operating in this area subject to delays."
