A few great things I have noticed is the serious improvement for weekends. Everything is now 15 minutes max between services on weekends. The blue mountains line has a great downward ultra express service in the morning. (possibly an endeavor service)
The newcastle services make mention of the "newcastle interchange"
Is the "ultra express" to which you refer the Up service ex Bathurst 07:40 Lithgow 08:47 Mount Victoria 09:15 Katoomba 09:32 and set-down-only at Springwood, Penrith, Westmead, Parramatta and Central? That is indeed 2N. There are also limited stop Up services from Mount Victoria 07:02, Katoomba 10:22, Mount Victoria 15:02 and 16:02 and 17:02, and Katoomba 18:22, all of which are 8V.
Have pity on those who want to travel between, say, Riverwood and Panania. Or between Glenfield and Beverly Hills. The previous seamless connections between all-stoppers to/from Revesby, and limited stoppers skipping Narwee-Turrella, have been disposed of. All day every day.
No not all day every day, the interchange station is now Padstow or Riverwood instead of Revesby.
Ex: Macarthur / Padstow / All Stops at Padstow (Wait)
06:39 / 07:13 / 07:16 (3mins)
06:54 / 07:28 / 07:31 (3mins)
07:09 / 07:43 / 07:46 (3mins)
07:24 / 07:58 / 08:01 (3mins)
07:39 / 08:13 / 08:16 (3mins)
and two in the afternoon peak arriving at Riverwood at 17:46 and 18:01 also with a 3 min wait for the connecting Campbelltown train.
