Mr Turnbull's group has collated pictures of proposed upgrades to Redfern Station from 1944. Plans were drawn up in themid-1990sfor underground concourses,while the former Labor government said it would fund upgrade designs in 2006.
In 2013,then transport minister Gladys Berejiklian broke with tradition by announcing the government would install a lift at Redfern. That lift,completed in 2015,enables passengers travelling on only one line,the Inner West Line,to move from the station platform to concourse without using stairs or escalators.
Commuters can change for this platform at Central. But the lift does not directly service the station's most heavily used lines,for instance the Western Line from Parramatta,or the Eastern Suburbs and Illawarra lines.
"Anyone who is coming into Sydney University or the new CBA or other developments on those lines aren't going to be able to use that lift,"said Mr Turnbull.
