THE state government predicts confusion on the city’s transport network could last a week as commuters adjust to the biggest ticketing shake-up for 20 years.Despite yesterday’s relatively smooth soft launch of the new MyZone system, the Transport Minister, David Campbell, warned that today – the first working day for new fare structures on trains, ferries and public and private buses – was likely to cause queues and delays.While vendors will be selling MyZone tickets at bus queues in the Hills area where private bus companies will use public transport tickets for the first time, and a roving team of 70 officers has been handing out information to explain how the system works, Mr Campbell urged commuters to be ready for problems.”Despite these efforts, commuters should still expect some delays in the early stages and I advise people to think about arriving at their train station, bus stop or wharf a little earlier than usual,” he said.”One day isn’t going to be the answer. Until we’ve had a full week of operation, we won’t see how it settles down.”Like many private bus users, Kellyville commuter Paul Gerrard has always bought a weekly bus ticket each Monday for his travel to the CBD.While he is pleased his old $50.40 ticket now costs only $34.30, it took him a week to find somewhere to buy one and he expects big delays this morning as fellow commuters discover they can’t buy a weekly ticket on the bus and will have to buy singles.Drivers will then have to mark each pre-purchased ticket as private buses do not have machines used on public buses which read and stamp the tickets.”Tomorrow the buses will be late, the timetable will be shot to pieces and people will ask why they don’t get back in their cars,” he said.Central station was quiet yesterday and for many travellers the only noticeable change was the cut in price the government says applies to most journeys.David Young, from Moss Vale, said he used to pay $22.50 for his return trip but yesterday the cost had dropped to $10.80.”You could say I’m fairly happy,” he said.The opposition transport spokeswoman, Gladys Berejiklian, said MyZone was ”essentially replacing one clumsy system with another”.
