If anything was to happen now they would just order an extra 1 or 2 new B sets instead of worrying about the old prototype waratah.Wrong
They would retro fit the existing in good order bodyshells.
No you are wrong. These days it would be easier and just as cheap to write off the set and build a new one.
How'd you figure that? One, two, three, even four cars is cheaper than writing off carriages that have nothing wrong with them and building a completely new set.
Gunzel a few points of order
1) What do you actually know of the condition of the prototypes before being left to rot?
2) Do you know if they were built to the same standards as the main production?
3) Do you know it will be cheaper to fit them out?
4) Do you know there is nothing wrong with them?
Airbus typically keep their prototypes, one of the two A380 prototypes retained by Airbus was used to trial the new A380 PLUS fit out. Neither plane will ever be sold to a customer. Boeing also retained its prototypes, again often used for testing during the life of the production and beyond.
While I agree the govt does at times have some questionable motives, do you think that they would basically scrap a perfectly good train when they are short of rolling stock? A 2 or 3 or 4 car Waratah could be used for Carlingford? Remember the recent press noise over the older non-AC stock?
I would strongly suggest that without any further evidence than " From what I've seen they look the same", you need to take others opinions and in some cases experience at face value and accept that these trains are economically not suited for final fit out and use in Sydney until you have actual data that proves otherwise.
