[7] The Ejanding Northwards Railway Act 1926 assented to on 16 December 1926, authorised the construction of the spur lines north of Amery, to be known as the Ejanding Northwards railway[8] with the contract for the construction awarded to Western Australian Public Works Department on 28 June 1927.

The new railway line was to split at Burakin, heading north from there to Kalannie and east to Kulja, with both officially opening on 15 April 1929.

A 35-kilometre (22 mi) long railway straight north from Kalannie was the board's preferred option for the extension.

The Beacon to Bonnie Rock section did not feature in this classification, being instead deemed an uneconomic line.

[17] The Cadoux railway siding is on the Shire of Wongan-Ballidu's heritage list,[18] and consists of a loading ramp and crane.

[20] On the spur line to Bonnie Rock, the railway barracks and station at Beacon are both on the Shire of Mount Marshall's heritage list.
