Metrolink passengers are being encouraged to check their journey, with disruption affecting most of the network this morning, Wednesday 15 March.
Damage to overhead lines, which power the trams, has resulted in fewer trams being able to run from Queens Road Depot than normal this morning.
There are currently no trams on the Trafford Park Line and a reduced service on some routes, with East Didsbury and Oldham and Rochdale lines most affected.
Other lines are operating with delays.
Metrolink passengers are able to use their tickets on selected buses and a dedicated information page has been set up to help passengers plan their journey.
The issue is likely to affect services into mid-morning. Metrolink tickets are being accepted on the 18, X50, and 250 bus services for those needing to get a tram on the Trafford Park line.
TfGM’s head of Metrolink, Danny Vaughan, said: “The overhead line issue this morning is impacting much of the network, with some delays or reduced frequencies and no trams currently on the Trafford Park line.
“We’re working with bus operators and other partners to help passengers make their journey as best as possible, and I’d encourage people to think about their journey this morning.
“If possible plan ahead, allow extra time and please bear with us while we work to get this issue fixed.
“We have engineers working on site and will continue to use our customer channels to provide latest updates.”
