Passengers are set to face disruption on the Metrolink network until the end of November.
Planned engineering works to replace a damaged rail in Piccadilly Gardens have been delayed, so a revised timetable has been introduced to start on October 24. There will be changes to trams on three lines.
They are the Bury and Altrincham line, Ashton line, and Eccles line. Transport for Greater Manchester (TfGM) says passengers using these services will still be able to get to the city centre, but alternative methods of getting around are available for cross-city trips.
