Tech to deliver more frequent Vic trains

Train timetables in Melbourne should be redundant in a decade thanks to high-frequency sequencing that will allow 10 extra trains to run every hour on every line.

The state is seeking expressions of interest for the first rollout of advanced high-capacity signalling on an existing Australian network.

Premier Daniel Andrews says it will allow more trains to run on any line, more closely, more often - like in Tokyo or Hong Kong.

"You can throw away the timetable. Trains will be there every two or three minutes," Mr Andrews told reporters on Thursday.

It will be constructed and trialled on the South Morang line next year before it is rolled out widely once the Metro line is up and running in 2026.

Protective screens on the edge of the platforms of five new stations within the Melbourne Metro will only open to let passengers get on and off carriages once the trains have stopped.

They are designed for safety and to stop people from walking on the tracks - a common problem within the City Loop.

Mr Andrews said the screens would also improve climate control and noise - and could be rolled out to other underground stations once the project was complete.
