The company operated the 1067 mm (3 ft 6 in) Silverton Tramway, conveying silver-lead-zinc concentrates 58 kilometres (36 miles) from Broken Hill to the South Australian border.

[1] In August 1899, the New South Wales Government Railways (NSWGR) purchased the Tarrawingee Tramway.

[1] Following a new 1435 mm (4 ft 8+1⁄2 in) standard gauge line being opened in February 1970 by the federal government, the line was made redundant and the company concentrated on operating shunting and track maintenance services to the mines industry in and around Broken Hill with its remaining two diesel locomotives.

[2][3][4] Under the 1886 Act, the Government of New South Wales had an option to buy out the company for 21 times the annual divisible profits of the preceding seven years.

[6][7] With the introduction of an open access regime in New South Wales the business was rebranded as Silverton Rail, and in August 1999 began operating iron ore services from Cobar to Narromine as a subcontractor to National Rail and relocated the majority of its fleet to Parkes Roundhouse.

Other services from the Broadmeadow Depot included the daily containerised freight service from Tolls Carrington to Port Botany and return, as well as crewing both ends of the Wee Waa to Port Botany export cotton trains.

[15] Following Allco Finance running into financial trouble, Coote Industrial was able to buy much of the former Silverton rolling stock in January 2008 through controlled subsidiary Greentrains.

[17][18] In April 2011, Qube Logistics acquired outright control and majority ownership of P&O Trans Australia and Southern & Silverton Rail was rebranded.

[19][20] Qube Logistics purchased New South Wales freight operator Independent Transport Group in June 2012.
