Western Sydney commuters have expressed frustration on the first day of the new public transport timetabling, with at least 10 minutes added to some trips.
People travelling from Macarthur to Parramatta now have to change trains, with this adding significantly to an already 40 minute trip.
"Talking to commuters here at Auburn, it's an 11 minute longer trip to the city," Leader of the NSW Opposition Luke Foley said.
"A trip on Friday that took 25 minutes now today takes 36 minutes because the express trains don't stop here anymore."
The CityRail twitter account has posted a video of 'timetable HQ', showing many staff on hand to deal with issues.
The NSW Government are encouraging commuters to stay patient as the largest change in public transport services across Sydney continues to be refined.
"There is going to be some wrinkles ironed out in the next 24 hours across trains and buses," NSW Minister for Transport and Infrastructure Andrew Constance said.
"People are going to have to adjust their travel patterns.
"We are urging people to look at the apps."
An additional 8,600 train, bus and ferry services have been added to the network.
