In short:
Footage has emerged of a moving Sydney Metro's carriage door being left wide open during Wednesday morning's commute.
The driverless metro service was running between Chatswood and Crows Nest about 8am.
What's next?
The incident is now under investigation, with the Rail, Tram and Bus Union calling on Sydney Metro to stop operations until interim safety measures are implemented.
Well, some of them are built so that the front doesn’t fall off at all.
