Anybody know when and which B Set will enter service? And which line / station it will begin from?
I remember seeing B2 on Wednesday night at Sydenham station, and B3 today at Auburn depot.
Just curious. So tired of having to take an S Set every morning, with it half the time being cancelled due to mechanical issues.
S-sets move around daily, and don't simply return to start to form the same service every day. So wherever the first B set debuts, it will be somewhere else the next day.
So for example, 18 run starting from Campbelltown in the morning (04:38 from Macarthur is its first revenue trip) is found at Eveleigh during the day, comes out of there at 16:57 and becomes a Leppington service, arriving there 18:42. Forms an Up service departing 18:54, via Granville, around the City Circle, out to Lidcombe via Bankstown (21:21), and then it proceeds empty and ends up stabling at Macdonaldtown and forming 24 run the next day.
Of course, what they might also do is an STN to specifically move that set back to a preferred location each night, so that (for example) that 04:38 from Macarthur is permanently a B set.
So the sad answer to your question is, really, we don't know.
