The TAs were an enhancement on the 1967/ 1968 built T Class (Tulloch 660hp C 1970-1971 38tons 65kmh).
These shunters were mainly used at works and power stations by Westrail.
TA1808 was built by Tulloch Limited at Rhodes, NSW with parts from Hawker Siddeley Brush of the UK (probably their Australian Division as they were active in Oz in that period).
