Trainstopic is just as wrong as you.
You use a old incorrectly labeled video with limited image of either side of the track as your only reference point and ignore someone who actually lives here?
Again Trainstopic is wrong
The line will only be as crowded as you say if the govt fails to procure more carriages to make the trains longer and increase the frequency. As the top end capacity more than doubles that of the DD lines then if it achieves that sort of capacity at 2m intervals with 8 car trains then I think your argument falls over as it has become a Metro as per your definition and proven the govt right.
Please give me the courtesy RTT of explaining why I am wrong. I don't want to get into semantics about what is classified as a "metro", but the simple fact is that most commentators would interpret a "metro" to be a frequent high capacity inner city rail service. It generally doesn't refer to a rail service stretching to the outer lower density suburbs, which the North West Rail Link is. The choice of rolling stock is therefore inappropriate. Whether it is single deck or double deck is beside the point, it needs to have a greater seating ratio because of the distance involved. What we are about to end up with is an inner city Hong Kong style service with limited seating over vastly greater distances in Sydney. Please don't bore me with any more comparisons with Dubai, as Sydney and Dubai are chalk and cheese. There's no comparison.
