As the 1950’s merged into the 1960’s, wholesale changes in the railway scene in New South Wales were becoming noticeable, particularly on the main lines of the state. 
The day of the 38 class hauled express trains were becoming a rarity as diesel electric locomotives entered service and took over there rosters. 
Heavy freight trains weren’t immune either, as many older steam locomotives had their numbers decimated.
As the disappearing of steam on the main lines was well under way, it was only a matter of time before an increasing number of branch lines saw dieselisation, a prelude in a number of cases, to line abandonment. 
Thanks to cinematographer such as the late Keith Atkins, who travelled extensively to record steam and railway operations in general through many parts of NSW from the late 1950’s through to the mid 1960’s, the vision of steam at work has been preserved.
