Engineers were out in force yesterday to trial one of the trams as the final tests of the long-delayed network got under way.
The tram, flanked by engineers and key personnel, was walked along the off-road section between Edinburgh Park and Haymarket to allow measurements to be taken and tests carried out.
More than 150 test journeys will now take place along the line each day ahead of the network being opened to the public next year.
Despite its troubled history, Edinburgh Council has said the tram scheme is in line with its revised budget of £776 million, approved September 2011.
Work to get the public transport system up and running is also either ahead of schedule or in line with the revised timescale reported in December 2011.
The council's project team has forecast that the service will open for passengers by May 2014, two months earlier than the original summer 2014 target.
Edinburgh Council Transport Convener Lesley Hinds said: "This is another long section now under testing and it means there's 11 km of track in use.
"Of course, there's more testing to come so we're very keen that the contractors have the space to do their work so we can keep pushing hard towards the service launch in May."
A city-wide safety and awareness campaign will also be launched this month with trams due to run through Edinburgh city centre.
The trams move at a top speed of 45mph on off road sections, and will comply with the speed limit on the road.
The council said that crossings should be treated like any other traffic signal controlled junction, where yellow box keep clear areas, road signs and traffic signals should be obeyed.
