Queenslander’s only train (8)
I believe the answer is:
anderson
'train' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'queenslander's only' is the wordplay.
'ANDERSON' is hidden within the letters.
But, I am uncertain how this is indicated.
Can you help me to learn more?
(Other definitions for anderson that I've seen before include "Sir John -, gave name to WW 2 air-raid shelter" , "Lindsay ____, English film director, d. 1994" .)
