And this small section is not even the actual rail tunnel.
Elsewhere the TBMs are being assembled at the North Melbourne station site and the two tunnel entrances at South Kensington and South Yarra are progressing well. The High capacity signalling(CBTC) trial site is about to start construction between Epping and South Morang.

The State Library station being built as part of the $11 billion Metro Tunnel project is starting to take shape, with the underground station's first platforms being carved out of the earth beneath Swanston Street.
A 200-metre long tunnel has been built beneath Swanston Street, forming a key section of the twin rail tunnels and passenger underpasses at the new station.
Two separate access shafts being excavated at Franklin and A’Beckett Street have now been joined underground via the new tunnel.
Three machines known as "roadheaders", each weighing more than 100 tonnes, have been digging deep into the ground for about eight months.
