Welcome to the Melbourne - Sydney Rail Corridor Upgrade Project.

This site provides you with detailed information about project works being undertaken by the South improvement alliance and key benefits the program will bring to the freight industry and the Australian economy.

The South Improvement Alliance (SIA) is the group of organisations brought together by the Australian Rail Track Corporation (ARTC) to plan, design and deliver a range of improvements along the rail corridor. On October the 28th, 2005, a three year alliance style contract was signed between ARTC and their partners, John Holland Rail, MVM Rail and O'Donnell Griffin (ODG).

The South Improvement Alliance also includes sub-alliance partners Kellogg Brown and Root (KBR), and CW-DC who provide specialist design services to the prime alliance partners.

This site provides you with detailed information about the program of works being undertaken and the key benefits the program will bring to the freight industry and to the Australian economy.
