If you’re a public transport regular, you’ve probably heard timetables are changing on Sunday November 26.

Transport NSW said in an official statement: “The changes mark the biggest ever change to our transport network.”

More than 1500 new train services, and 750 new weekend train services a week will be introduced.

The northern beaches, eastern suburbs, inner west, lower north shore and northern suburbs, Macarthur and hills districts will see almost 7000 new weekly bus services introduced.

More than 140 new weekly ferry services (including a new cross-harbour ferry route linking the eastern suburbs, lower north shore, inner west and Sydney CBD) will also launch.

If you’re travelling around the northern beaches and lower north shore there will be 2000 new weekly B-line bus (a new fleet of double-decker buses) services.

“The changes will increase capacity so we can deliver more services and provide better connections between trains, buses and ferries,” a Transport NSW spokesperson said.

Existing bus and ferry timetables will change to align with the new train timetable.

The one aspect that’s not changing? Peak and off-peak times for Opal fares.
