They were rostered to haul express trains between
Sydney and
Junee, replacing their smaller cousins. Around 1912, three of the class were transferred to
Junee Locomotive Depot to work the section of the
Main South line from there to
Albury where they turned in a reasonable performance over this easy section. The other two were sent to
Armidale for working the
Brisbane Mail from
Werris Creek to
Wallangarra, however this move proved unsuccessful and they too were sent to Junee. Some mechanical improvements were made in 1919 and they continued working south of Junee until the new
36 class locomotives began to work these trains from Sydney through to Albury from 1928. They were then transferred to
Taree to work on the
North Coast line. Their rough riding characteristics made them unsuitable on the almost continuously curved route and they returned to Junee in 1935, where they were assigned to assisting expresses to
Wagga Wagga and working the
South West Mail from Junee to
Hay. ==Withdrawal==
