Question: What is the name of this only interstate railway station in South Australia, where Silver City Limited operated between it and Broken Hill?
Context: Silver City, Pinos Altos and Mogollon Railroad (SC,PA&M) was a narrow gauge railway serving copper mines along the Continental Divide in the mountains of southwestern New Mexico.  The communities of Silver City and Pinos Altos developed as 19th century miners recovered easily extracted gold and silver from ore deposits of the area.  Standard-gauge Santa Fe Railroad reached Silver City in 1886, and SC,PA&M was incorporated 24 August 1889 to build a railway north to Mogollon, New Mexico.  Construction was limited to 5 mi of grading until Wisconsin-based Comanche Mining and Smelting purchased the railroad and the Pinos Altos mining claims of George Hearst in 1903 after horse-drawn ore transport became uneconomical.  The Silver City smelter burned shortly after purchase, but was rebuilt with three blast furnaces and a reverberatory furnace to handle 225 tons of ore per day.  Two Shay locomotives were moved to Silver City in August 1905 from the Gilpin tramway of Gilpin County, Colorado.  The railroad was built through iron and limestone mines on Chloride Flat west of Silver City.  The limestone was used as a flux for smelting the copper ore.

The Silver City Limited was a passenger train operated by Australian National between Adelaide and Broken Hill. Broken Hill was an electoral district of the Legislative Assembly in the Australian state of New South Wales.  From 1894 to 1913, the Broken Hill district was covered by the electoral districts of "Broken Hill", Willyama and Sturt.  In the 1912 redistribution, the electoral district of "Broken Hill" was abolished and absorbed into "Willyama" and "Sturt".  In 1920, "Willyama", "Sturt" and the electoral district of Cobar were combined to create a three-member "Sturt".  In 1927, single-member electorates were recreated and the city of Broken Hill was split between "Sturt" and Murray.  From 1932, the city of Broken Hill was split between "Sturt" and Cobar.  In 1968 "Sturt" was renamed Broken Hill and included all of the city of Broken Hill.  In 1999, it was merged with part of "Murray" and renamed the electoral district of Murray-Darling.

Silver City Airways was a private, British independent airline formed in 1946.  The name "Silver City" was derived from the eponymous Australian mining town at Broken Hill, where "The Zinc Corporation" was headquartered.  Silver City's first commercial flight departed London Heathrow for Sydney via Johannesburg in late 1946.  The following year, Silver City leased its first Bristol Freighter, moved its base to Blackbushe and participated in the airlift of Hindu and Muslim refugees between Pakistan and India.  In 1948, control of Silver City passed from the Zinc Corporation to British Aviation Services.  In July of that year, the airline inaugurated the world's first air ferry service across the English Channel between Lympne Airport and Le Touquet Airport.  In 1948–49, Silver City participated in the Berlin Airlift.  In 1949, it established a French sister airline.
