Platform screen doors are used in some of the world’s leading underground rail networks including London, Hong Kong and Paris.
The platform screen doors are aligned with the doors of the train and they open and close automatically when trains arrive at and depart stations.
They improve passenger safety and boarding times, help manage the station environment and improve tunnel ventilation.
Each of the new stations has been fitted with 60 platform screen doors made of toughened glass.
There will be clear entry markings to make it easy for passengers to know where to wait for their train.
This will be the first time the technology has been used in Melbourne.
