I'd say there would be guaranteed rider requests from the latter two stations every single week day morning! And North Sydney in evening peak hour! Let alone other times as well. http://www.abc.net.au/news/2017-04-20/overcrowding-fears-for-sydney-train-stations/8449138
When I first took a train from Epping's underground platforms i noticed that the space on the above ground platforms was very limited even at the best of times. Try doing it in peak hour and its insane. Like mosh pit where you come up an escalator with nowhere to go! Especially scary because there are no barriers on the edge of the platform so people can fall into oncoming express trains or goods trains that don't even stop at that station.
We were taking train late night back to pullman homebush and for that last little connection we had - i swear - a brank spanker full on train all to ourselves Very eery and surreal - felt like being in a scifi movie of some distopia - where machines do all the work and humans just wander around in some artifical world in semi isolation trying to stay interested and sure ive read a lot of scifi
