Melbourne’s Comeng trains date back to the early 1980s, about the same time us Gen-Xers were cutting our video game teeth with Donkey Kong and Space Invaders.
There’s certainly other things of the 80s around the place on the train network, for instance this sign on a now unused gate at Caulfield Station. (Since then we’ve had a new Met logo, then Bayside Trains, then M>Train, Connex, now Metro.)
Retro Metro have done that harks back to days of yore is to put staff back on busy platforms. While I was surprised to see Sydney rail staff waving a flag a few years ago, here they’ve been given high-tech looking paddle devices (the other side has LEDs that stand out to the train driver).
