Noteworthy article describing male railway worker (9)
I believe the answer is:
signalman
'railway worker' is the definition.
(I know that signalman is a type of railway worker)
'noteworthy article describing male' is the wordplay.
'noteworthy' becomes 'signal' (I've seen this before).
'article' becomes 'an' (English indefinite article).
'describing' indicates putting letters inside (describe can mean to form the outline of).
'male' becomes 'm' (common abbreviation).
'signal'+'an'='signalan'
'signalan' placed around 'm' is 'SIGNALMAN'.
(Other definitions for signalman that I've seen before include "one controlling traffic movement" , "Railway worker" , "Main slang (anag.)" , "Railway employee controlling points" , "Rail worker" .)
