A MASSIVE £640 million revamp of the Metrolink tram line will begin in May.

Replacement bus services will be provided for commuters as 20 miles of worn-out track on the Bury and Altrincham lines are replaced. Work on the Bury section should be completed by the end of September.

Greater Manchester Passenger Transport Executive's Director General, David Leather, said: "The track on the Bury and Altrincham lines is more than 50 years old in some places and is rapidly approaching the end of its natural life. It is noisy for residents and uncomfortable for passengers. It is also making the service unreliable as the Metrolink vehicles need frequent repairs."

More than £102 million is to be invested on improvements to the network, including new ticket machines, stop upgrades and the introduction of eight new trams.
