Massive Suburban Rail Loop For Melbourne

The Victorian government has announced that a massive, $50 billion, underground suburban rail network will be built, linking every major rail line in Melbourne and the new airport rail, on completion commuters need not to travel into the city and back out to reach another part of Melbourne. The 90 kilometres of track would connect 10 train lines. The lines would be fully underground from Cheltenham to Melbourne Airport, and partially underground between the Airport and Werribee.
The loop would connect 15 stations in total, with interchanges built at 10 existing stations. Work on a 25-kilometre section from Cheltenham to Box Hill will begin by 2022 and is expected to take about a decade to complete. Construction on the section between the Airport and Sunshine would also start in 2022.
