The first part to be built was a horse-drawn tramway between the port at Wallaroo and mines near Kadina in 1862, followed by mines near Moonta in 1866. This was originally constructed as 5 ft 3 in (1,600 mm) gauge.
HOYLETON TO PORT WAKEFIELD HORSE DRAWN TRAMWAY
A separate isolated horse-drawn tramway[2] was constructed to deliver grain from the plains east of Port Wakefield in the areas of Balaklava, Halbury and Hoyle's Plains (now Hoyleton) to that port. It opened in 1869.[3] The section from Hoyleton to Balaklava eventually became part of the Hamley Bridge-Gladstone railway line when that line reached Gladstone in 1894.
CONVERSION TO RAILWAY AND EXTENSION TO KADINA
The 3 ft 6 in (1,067 mm) gauge line from Port Wakefield reached a new junction with the Kadina–Brinkworth railway line at Kadina and opened on 9 October 1878. It continued to Wallaroo on a new track adjacent to the older broad gauge track.[4] The line from Kadina to Barunga Gap had started construction from the Kadina end in 1877[5]
CONVERSION TO BROAD AND DUAL GAUGE
On 1 August 1927, the line was converted from 3 ft 6 in (1,067 mm) to 5 ft 3 in (1,600 mm) broad gauge.[6] A junction at Kadina connected to the Kadina–Brinkworth railway line. The section from Kadina to Wallaroo was converted to dual gauge broad and standard gauges on 2 December 1982 after the Adelaide–Port Augusta railway line was converted to standard gauge.
CLOSURE AND REMOVAL
The section from Balaklava to Paskeville closed on 4 April 1984, followed by the Wallaroo to Moonta section on 23 July 1984. The broad gauge section from Kadina to Wallaroo also closed on 23 July 1984, but the standard gauge line remained open until 3 March 1993. The Paskeville to Kadina section closed on 14 March 1990.
LIONS CLUB OF YORKE PENNINSULA TOURIST RAILWAY
[7] After the closure of the railways, part of the line was used by the Lions Club of Yorke Peninsula Railway for heritage tourist services, but the operations stopped in 2009.
The line between Wallaroo and Kadina has since been pulled up and replaced with the Copper Coast rail trail and retail stores on both ends.[8]
