Once the new regional fleet is operational the Xplorers will be used for local shuttles while the new trains will run in to and out of Sydney in the peak hours.

Lithgow is also not the same as macarthur and campbelltown. The 2 main south stations have at least 20 trains an hour entering and leaving. Lithgow is lucky to have 2 and so maybe the shuttle could be extended to mt victoria where more DD services are available.

People need to remember that with the Sydney system being so busy that it is extremely inefficient to run a 2-4 car single deck train on a path where an 8 car double deck train could run.
