[1][2][3] Following the electrification of the Sydney inner suburban lines from 1926, 77 of the 30 class 4-6-4 tank locomotives were converted to tender type.

Some engines were given entirely new extended smokeboxes fully supported by the frames, giving these few a more modern, purposeful look.

In their heyday, they could be found working almost every light branch line in New South Wales.

Even in the final years of steam power, they could still be found well spread over the state in such places as Temora, Griffith, Cowra, Dubbo and Narrabri West.
