Thousands of new services will be added to public transport timetables from late November, the NSW government has confirmed.

From November 26, new ferry services, extra weekly train services and thousands of new bus services will start running to reduce journey times for commuters.

Minister for Transport and Infrastructure Andrew Constance launched a campaign to raise awareness about the changes on Sunday and said it would help customers prepare for the changes and plan their new commutes ahead of time.

"We are going to make sure everyone knows these timetable changes are coming so from today, customers can expect to see an extensive advertising with plenty of information and announcements at stations, ferry wharves and on buses across the public transport network," Mr Constance said.
