A tram is stuck at Manchester Victoria station due to a problem with the brakes.
The incident is causing delays to Altrincham, Bury and East Didsbury services, while Manchester Airport trams have been diverted to Piccadilly.
A passenger stuck behind the faulty tram said they have been told it is not moving because 'the brakes are stuck'.
She told the M.E.N: "I'm stuck on the tram behind the one with the fault so we're only a few metres away from the platform at Victoria.

"We've been here for about 20 minutes now - our driver has said the brakes are stuck but that it should be fixed 'soon'."

Passengers have also complained they are stuck at other stations on the network.
