Sydney University has warned of the "serious impact" on thousands of students, staff and other commuters of a decision for trains on the Blue Mountain Line to no longer stop at Redfern station, making their trips "lengthier and more challenging".
In a swipe at the state's transport agency, vice-chancellor Michael Spence said the decision for trains on the line to bypass Redfern in favour of Central Station had "added greatly to the university's already significant public transport pressures".
"We are disturbed that we were not consulted about such a significant change," he said in a letter to the state opposition.
Dr Spence said Transport Minister Andrew Constance had identified demand for trains "going through the roof", and "yet he had allowed a timetabling change which makes train travel for thousands of our students and staff lengthier and more challenging".
In a sign it has lost patience with the government's plans to improve transport links, Dr Spence has told the state opposition that "you have the University of Sydney's support in your ongoing advocacy on this vital transport issue".
"I know you will be advocating on behalf of those who will be suffering the ill-effects of this change," he wrote in the letter to Labor's transport spokeswoman, Jodi McKay.
Labor has vowed to review the new timetables and "correct the bias against western Sydney" if it is elected to government at the state election in 2019.
Ms McKay said Mr Constance had made life difficult for up to 10,000 students and thousands more who worked at the Australian Technology Park "and he didn't think to tell anyone about it".
"It's disturbing, but not particularly surprising, that he overlooked the needs of thousands of students and workers and didn't bother consulting them," she said.
