Sunbury line will be merged with the Dandenong lines and operate as an end-to-end service through the tunnel. Work to extend platforms and upgrade traction power, in order to enable the operation of High Capacity Metro Trains on the Sunbury section of the new line, was funded in 2019. The works will include power and track improvements to trains travelling through the Metro Tunnel, overhead electrification works between Sunbury and South Kensington and at South Yarra, signalling power upgrades and additional infrastructure at Calder Park sidings. The works are being designed by Aecom and undertaken by CPB Contractors and John Holland Group.
