Today was a fairly significant milestone in the double tracking of the Western Line, with the new track opened up all the way through to Henderson.
In this article, Newstalk ZB decreed that the entire line has been double tracked. I'm not sure if their definition of entire means 'the entire line (apart from 4 stations)' or whether they consider that finished means 'no tracks, no second platforms, but some digging has been done', or whether they just screwed up. (Note that the entry could have been fixed by the time you read it, if you do, because being the pedantic nitpicker that I am, I emailed them to point it out).
I found it interesting that there was very little fanfare about this on the Maxx website, and I had trouble finding any coverage on the Herald site (although apparently there was a small piece in the physical paper version). The Newstalk ZB article was all I could find. Apparently there's a new timetable coming in a couple of weeks, with some new peak hour services on the way - nice, although I'll believe it when I see it!
