End of new tramline? (8)
I believe the answer is:
terminal
'end' is the definition.
(I've seen this in another clue)
'new tramline?' is the wordplay.
'new' is an anagram indicator.
'tramline' is an anagram of 'TERMINAL'.
'of' is the link.
(Other definitions for terminal that I've seen before include "Ending; airport building" , "At the end, final" , "Deadly" , "Arrivals or departures building" , "confirming departure" .)
