TRAM services have been resumed across Greater Manchester after a "major communications failure" sparked hours of travel chaos.

Transport bosses had been forced to shut down the entire Metrolink network because of the fault, which prevented any announcements being made at stops.

The failure, which occurred at about 11.30am, also meant that the network control room staff were not able to monitor tram movements or access information displays.

All services are now running again, but TfGM officials have warned to expect severe delays.

A Metrolink spokesman said: "Engineers have now identified and rectified the fault which brought trams to halt earlier today and safety critical systems are now coming back on line – but services are expected to be disrupted throughout the evening.

"Replacement bus services will remain in place and Metrolink tickets are being accepted on Northern and Transpennine Express rail services. Line by line information can be found on the Metrolink website – www.metrolink.co.uk.

"A 12 minute service will be restored throughout the evening peak."

Peter Cushing, Metrolink Director, said: “It’s good news that the issue has been identified and resolved and I’d like to apologise to anyone who has been affected by today’s network issues.

“We are now concentrating on getting services back up and running as quickly as possible and we are aiming to restore a 12 minute service across all lines this evening.”

Customers are advised to monitor the Metrolink and TfGM Twitter accounts for further information.
