A rival poll, however, released this week by the Rail, Tram and Bus Union suggests a grim mood among frontline staff.

According to the survey of 1040 bus and rail workers, 50 per cent say the quality of public transport in NSW has deteriorated in the past four years. A bit more than 20 per cent say it has improved, while almost 30 per cent of workers say it has stayed the same.

"She has put services back on, you can't argue that point," the NSW secretary at the RTBU, Alex Claassens said.

"But we believe that security in the network has gotten worse," Mr Claassens said. "And if you didn't have a Liberal government you would still have had ticket windows," he said, referring to the impending closure of dedicated rail ticket seller positions.

The survey results also suggest staff members weary of organisational change. Almost 60 per cent of staff said they had no confidence in management.
