Businesses along the route of the new tram extension in Birmingham say they're angry the project has been delayed again after safety tests found problems with the track.
Firms have received compensation for the over running works, but some say they're still surviving on a knife edge.
The £128 million upgrade and extension was meant to start carrying passengers all the way to and from Grand Central station this weekend.
Those in charge of the work say the setback is 'bitterly disappointing', but they must get everything right before the route can open to the public. Chris Halpin reports.
