The Metro Tunnel has entered full peak-hour operations, with the Big Switch activating additional services on the Cranbourne, Pakenham and Sunbury lines.
The milestone follows strong public interest in the new network, with more than 800,000 passengers visiting the tunnel’s new stations and trains travelling more than 64,000 kilometres since the system opened on 30 November 2025.
During peak periods, trains are now arriving at Metro Tunnel stations every three minutes. Services are running at least every 10 minutes between Watergardens and Dandenong in both directions for most of the day, seven days a week.
Frankston Line trains have also returned to the City Loop for the first time in five years. Services now operate anticlockwise around the loop and no longer run cross-city to Werribee or Williamstown.
The Metro Tunnel represents the largest transformation of Melbourne’s public transport system in four decades and has doubled the size of the city’s underground rail network.
