The consortium CPB Contractors, Ghella and Acciona Construction have secured the EUR 2.20 bn (AUD3.6 bn) Tunnels South contract to build 16km of twin tunnels between Cheltenham and Glen Waverley for Suburban Rail Loop (SRL) East in Melbourne. Tunnelling will start in 2026, and trains will be running by 2035.  

The 4 TBMs for this section will be powered by renewable electricity, and construction and materials emissions will be reduced by 20%. 

The contract will also include 55 safety cross passages between the tunnels, station boxes at Clayton and Monash and the construction of portals – the entrances and exits to the tunnels – at the stabling facility.  

Construction is progressing across the SRL East corridor, with works in Burwood underway to build the TBM launch site. Most of the ground preparation works required to excavate safety cross passages between the twin tunnels will be managed underground, reducing surface impacts on residents, schools and roads.
