an study released by the state government in 2001 showed over 1 in 4 (27.2%) of the machines at train stations did not work, and 11.9% of mobile equipment in buses and trams was non-operational. the state government renegotiated with ticketing network contract operator "onelink transit systems" to improve the service to commuters. following these improvements, a 2002 audit showed an increase in availability of machines to 92.1% at train stations, and 98.3% on buses and trams. usability was also improved, with tram machines able to sell daily tickets. furthermore, vandalism across the network dropped by 62% between 2001 and 2002.
