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.

[4] The line from Kadina to Barunga Gap had started construction from the Kadina end in 1877[5] 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.

Following the conversion of the Adelaide-Port Augusta railway line to standard gauge in 1982, the broad gauge line from from Balaklava to Paskeville was no longer required and closed on 4 April 1984.

[8] 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.
