Passenger and freight rolling stock provider Downer EDI has won rail contracts and extensions in Australia worth A$300m (US$297.9m).
The company said rail freight operator Pacific National has ordered 13 standard gauge diesel electric locomotives to support its coal haulage services in New South Wales.
Downer Rail will deliver the fleet from 2011 to mid-2012.
Downer's rail infrastructure business has also been contracted by Australian Rail Track Corporation (ARTC) to undertake rail upgrades as part of the federal government's Nation Building Rail Investment.
The works, to be carried out over two years, include track duplication projects across NSW and Victoria, re-railing of track between Albury and Geelong, signalling separation work between Enfield and Port Botany in NSW and the upgrade of rail lines in Victoria.
The company's rail infrastructure business has also won an 18-month extension of the V1 Alliance with ARTC for rail track maintenance and infrastructure work in Victoria and southern NSW.
