The service, which will see tram-trainsÂ run from Sheffield Cathedral toÂ Parkgate Shopping ParkÂ via Rotherham Central railway station, will launch on OctoberÂ 25.
It is almost three years late and five times over budget.
The long-awaited launch has sparked debate among Star readers online, with some already calling for it to be extended to Doncaster.

Steven Ryder said: 'I used to go to Doncaster on the bus every Saturday and it took 90 minutes to get there so if the '˜Team Rail' thing had gone there it would have been a lot quicker.'Â Â
Shaun Archer bemoaned the fact that it was delivered so lateÂ and said: 'Glad IÂ wasn't waiting for that to arrive at the tram stop -Â three years late!'Â
Others were just relievedÂ to see that it is finally due to be launched.
Mila Davis said she was 'excited' for its arrival, while Danny Epton added that it will be 'easierÂ than (using) buses.'
Sara Ahmad was pleased that this will provide 'anotherÂ way to get into Sheffield' for people coming from Rotherham.
In the end the scheme cost aboutÂ Â£75.1 millionÂ compared with an initial estimate of Â£15m when plans were first approved in 2012.
Tram-trains were due to begin running in December 2015Â but the project underwent numerous delays before its due launch towards the end of this month.
Cost increases were blamed on a number of issues such as the work being more complex than expected and the condition of railway infrastructure being worse than initially assumed.
The modification of the network has been part-funded by the Government and managed by Network Rail.
