 Work began in 2005 on upgrades between Sunshine and Ballarat as part of the Regional Fast Rail project, which saw heavier tracks and concrete sleepers installed, renewal of ballast and a new signalling system.A number of deviations were built to ease curves on the line, as well as seven new bridges, with the Lal Lal Creek and Moorabool River bridges amongst the longest in Australia.The works were completed and the first VLocity train ran on the line on 22 December 2005.
