In 1961, the Emu Bay Railway placed an order for three diesel-hydraulic locomotives with Tulloch.

[1][2] However before they were built, Tullochs entered administration and the order was transferred to Walkers Limited.

[7][8] All were included in the April 1998 sale of the Emu Bay Railway to the Australian Transport Network.

Following the June 2000 closure of the Hellyer Mine, all were stored and disposed of to preservation organisations.
