You think it is a problem now?
The trams and traffic have yet to face a real peak. When workers, school and Uni students are all back in Feb, then you will see the full disaster.
Then the extension down to Kingsford. The trams were launched now because they were hoping the lower patronage would help PR.
The Ministry of Transport are already predicting that in a full peak the trams will run @ 108% capacity. In 5 years that will increase to 120% capacity.
Add to that they are selling (sorry franchising) the buses, in 4 years time the ANZAC Pde corridor will make Parramatta Rd look like a freeway.
