Q & A about uniform on railway creates a dilemma (8)
I believe the answer is:
quandary
'a dilemma' is the definition.
(synonyms)
'q a about uniform on railway' is the wordplay.
'a' becomes 'an'.
'about uniform' becomes 'uda' (I can't justify this - if you can you should believe this answer much more).
'on' is an insertion indicator (as in clothing 'on' a person).
'railway' becomes 'ry' (abbreviation).
'an' inserted into 'uda' is 'uanda'.
'q'+'uanda'+'ry'='QUANDARY'
'creates' is the link.
(Other definitions for quandary that I've seen before include "Problem" , "State of perplexity in difficult situation" , "Predicament - dilemma - uncertainty" , "awkward situation" , "State of uncertainty as to action to take" .)
