Pedestrians should be able to walk the first section of Sydney's version of New York's ''High Line'' by the end of the year with construction due to start this month.
But the latest plans for the goods line walkway - a redevelopment of a little-used rail corridor between Central station and Darling Harbour - show it is expected to be much more than a pedestrian thoroughfare.
Pop-up bars, cafes, performance stages, ''study pods'' and electronic screens are all planned to line the border of the goods line, a 500-metre stretch linking Central with Haymarket, Ultimo and Darling Harbour.
The line - part of which will consist of raised walkways - is to be built in two stages.
The first, and northern, section of the line runs from the Frank Gehry-designed Dr Chau Chak Wing Building being built at the University of Technology, Sydney to the Powerhouse Museum.
And on Saturday, Planning Minister Brad Hazzard released new images of the southern section of the line, which will run past the ABC at Ultimo and link with the pedestrian walkway under Central and Railway Square.
"The goods line south has already generated interest in redevelopment from landowners in the surrounding area, who can see the great advantages this new facility will offer for economic and property development," Mr Hazzard said.
The goods line was originally billed as a pedestrian and cycling thoroughfare. But the images of the southern section of the goods line raise the question of how well cyclists will fit in what is shown as a busy thoroughfare, flanked by pockets for retail and live entertainment.
The president of advocacy group BIKESydney, David Borella, said the group supported the creation of places that led to good outcomes for both walkers and cyclists. But he said the design should cater for the passage of low-speed cyclists.
''Like water, cyclists will find the path of least resistance and will tend to want to use the corridor,'' Mr Borella said.
Work will begin on the northern section of the goods line this month, and is expected to be finished by November, soon after the Gehry building is due to open.
A spokeswoman for Mr Hazzard said the south section of the line would go to tender late this year, with construction starting early next year.
