Not sure if I've posted here already, but "Aunt Gladys" lied in a media release about these Waratah trains. She claimed in “her” media release that not one Waratah carriage was delivered while Labor was in power. That is a lie as I have video of A02 being delivered BEFORE Liberals got in. And at the same time, found another Watarah train video showing they were being delivered about 5 months or so before my video.
I thought they weren't having STNs to "hide" when they arrive at Cardiff - for obvious reasons.
Perhaps by delivered, she was using the term as it would apply to passengers understanding - delivered, as in entered service. The general public don't care if they're "delivered" from the wharf to the workshop, or from the workshop to a different workshop in Sydney, they only care if they're in service. So whilst she might appeared to have lied in a physical sense of the word, consider who the address is aimed towards. If you tell Sydneysiders that ten sets have been delivered but none are in service, what would they care?
As for the no-STN thing, it's mostly as-hoc when they arrive at the wharf, so they're pathed accordingly by train control. No time to draw up and STN and no point. Everyone involved knows what's happening, it's just another train to them, no different from an extra freighter...
The no-STN thing for entering service is simple - the SWTT states what rosters are worked by A Sets. What set number is on that run is irrelevant. The Telegram/STN's were for runs previously operated by silver sets, to ensure that all stakeholders (maintenance, crewing, etc) understood that they were now Waratah trains.
