So, according to paywalled articles this morning in the SMH and DT:
“Sydney’s $21.6 billion metro rail line under the harbour and CBD is set to open to passengers in August after trial running of a full-service timetable started on the driverless train link.”
Finally!
I belong to a couple of rail groups on Facebook. It's hilarious that some people are triggered by driverless trains - this really exemplifies conservatism as opposition to change purely for the sake of it.
Strictly speaking, this announcement is a delay since a July launch date has been kicked around for months. But given that mega-projects are routinely delayed by years, it is a very welcome announcement.
