The government announced today the final version of the October 2013 timetable. Much has been written on this topic in this blog so far this year, so links to that have been included below rather than just repeating it all over again.
One of the less publicised improvements is the extension of the 10 minute frequency network. Currently, trains on the Eastern Suburbs Line between Bondi Junction and Sydenham run every 10 minutes between 5AM and 9PM on weekdays. This will now be extended through to midnight. Meanwhile, trains on the North Shore Line between Central and Chatswood will run every 9 minutes (Southbound trains) and 11 minutes (Northbound trains) between 5AM and 9PM, while trains on the Airport Line between the City Circle and Wolli Creek will also run every 9 minutes between 6AM and 10PM.
