I also don't think the design is the issue - as with any design which gets evolved into the next generation there were major changes to the body and crashworthiness structures of the older B-series unit, but the high value components would all be pretty well exactly the same with the exception of certain safety systems.
I would speculate that it is due to one of two possibilities:
1. Shelving the A-City order to prioritise orders for Victoria where it's about business and not about favours for Labour's buddies which can be completed whenever they feel like it.
2. Possible supply shortages for the high value components which come from Europe (or possibly India for the bogies) as there has also been talk of Bombardier having component supply issues for their current Electrostar order. The Electrostar units are similar to ours in that the majority of the manufacturing spend is in Europe and they get assembled at a factory in the UK.
Seems a bit strange that South Australia is having trouble with the delivery schedule mainly meeting deadlines…There is no evidence anywhere to suggest there was ever a schedule or deadlines, apart from the Department revoking or modifying their promises to the public as fast as they make them in the first place.
I have written to the two Independent MPs asking them to use the balance of power in the new Parliament to force a Royal Commission into the Bombardier deal and find out who was on the take. The next four years present a valuable opportunity to clean up the state, even if Bob Such resigns due to his cancer issues the Liberals will certainly win the by-election and there will still be a minority government.
