Unfair clue, not quite cryptic, for 'type of railway' (9)
I believe the answer is:
funicular
'type of railway' is the definition.
'unfair clue not quite cryptic' is the wordplay.
'not quite' means to remove the last letter.
'cryptic' is an anagram indicator.
'unfair'+'clue'='unfairclue'
'unfairclue' with its last letter taken away is 'unfairclu'.
'unfairclu' anagrammed gives 'FUNICULAR'.
'for' acts as a link.
(Other definitions for funicular that I've seen before include "(Of a railway) cable-operated" , "Using a cable" , "Railway up the side of a mountain" , "Cable railway" .)
