Neat kind of trams (5)
I believe the answer is:
smart
'neat' is the definition.
(synonyms)
'kind of trams' is the wordplay.
'kind of' indicates an anagram.
'trams' with letters rearranged gives 'SMART'.
(Other definitions for smart that I've seen before include "Clever or stylish" , "Clever or dapper" , "astute" , "Clever; sting" , "Chic; sting" .)
