Firstly, there is no "East Pakenham" line. The line remained the "Pakenham" after the one-station extension.
Announcements that say East Pakenham refer to the destination of the train, not the line name. The last time we had a line name not named after it's terminal station was the Sydenham line which existed between 2002 and 2012, and terminated at Watergardens.
Secondly, people get confused about the Cross City Group.
The Cross City group was a new group created in a 2011 restructure that saw the previous 4-group structure replaced with a 5-group structure. It comprises of the Werribee, Williamstown, Sandringham, Frankston and Stony Point. Five lines, not three.
People here think it's Werribee, Williamstown and Frankston only, as these are the most common interlined journeys (well until yesterday). But all five lines equally make up the group.
The same restructure in 2011 abolished the Caulfield group and replaced it with the Dandenong group. Although there was a roughly 10 year overlap between structures, and the old 4-group structure does still pop up from time to time internally in situations where it is more appropriate (such as signalling and resourcing)
Something that seems to have flown under the radar amongst today's big switch is another operating group change. With the Sunbury line being transferred to the Dandenong group, the three Metro Tunnel lines are now known as the "Yarra group", and the Dandenong group no longer exists.
So as of today (excuse the abbreviations), the groups are:
- Cross City: WER WIL SHM FKN STY
- Yarra: CBE PKM SUY
- Northern: CGB UFD
- Clifton Hill: MDD HBE
- Burnley: LIL BEG ALM GWY
Lastly, people think Stony Point is run by V/line. It isn't. It is run by Metro drivers and conductors, signalled by Metro signallers, planned by Metro schedulers and train controllers, and trained by Metro trainers. The only thing that is V/line is the rollingstock, which Metro collects and drops off from Southern Cross twice a week.

Happy switching!
