The conversion proved successful and a further 19 had been converted at Eveleigh Railway Workshops by 1902.

[1][2][3][4] Following the delivery of C30 class locomotives from 1903, they were transferred to Newcastle suburban traffic and when replaced there, were allocated minor roles such as working the Carlingford, Morpeth and Warren branches.

Two were sold to East Greta Mining & Railway Company, one to Ashtonfields Colliery, Thornton and a fourth scrapped.

In later years, their main duties were working of the Ballina branch, the Picton to Mittagong Loop line, the Yass Town branch and school trains on the North Coast line from Coffs Harbour to Kempsey and Casino to Border Loop.
