Laing O'Rourke has won a A$10.2m ($10.2m) project development contract for electrification of the rail network in Adelaide in the state of South Australia.
The rail network in Adelaide consists of five lines and 81 stations, totalling 125.9km.
The enhanced electric rail system with new trains, signalling and communication systems will cover the track across the metropolitan area from Gawler to Seaford, and Adelaide to Outer Harbor.
The modernisation work will commence next year and is part of the country's A$400m electrification programme.
The first electrified services will run on the new Seaford rail line in 2013, and subsequently on the Noarlunga and Gawler lines by the end of the year, with electrification of the Outer Harbor line to be complete in 2015.
The Adelaide rail electrification project will boost the Adelaide transport network by modernising the lines and bringing international companies to South Australia, according to the Australian Government.
