As far as Lidcombe is concerned, the new timetable is really not ideal for people who travel from the Bankstown Line to stations served only on the Inner West Line. It's also not just that, because there's also some people who want to change to the Northern Line at Strathfield.
With the new timetable, the line has been cut at Lidcombe but despite Lidcombe now becoming an even more important interchange than it already was (as the interchange point between trains towards the Auburn direction, Bankstown Line and Olympic Park Line previously) there has been no recognition of that at all it seems.
The full train load at Lidcombe that would have been on the Bankstown Line service now needs to get off and change trains to continue their journey. However, there doesn't seem to have been any increase in services to/from Strathfield which would be necessary, so those people intending to travel to the Inner West Line stations or to the Northern Line can have a more convenient interchange.
Seeing as there will be less services now between Lidcombe and Strathfield during peak hour with the loss of the Bankstown Line/Inner West Line services, and the need for everyone on the Bankstown Line train to get off and change trains to continue their journey, there's going to probably be some serious congestion at Lidcombe.
Both before and after the new timetable, only 4 trains per hour one way during peak on the Western Line stop at Lidcombe.
With approximately 20 trains per hour on the Western Line passing through the Lidcombe location one way in peak, I think they should have put on some of the slower patterns to stop at Lidcombe, maybe another 4 trains per hour to bring the total to 8. This combined with the South Line would probably be better.
