Wrong line and tram station (8)
I believe the answer is:
terminal
'station' is the definition.
(I know that terminal is a type of terminus)
'wrong line and tram' is the wordplay.
'wrong' indicates an anagram.
'and' is a charade indicator (letters next to each other).
'line' after 'tram' is 'tramline'.
'tramline' anagrammed gives 'TERMINAL'.
(Other definitions for terminal that I've seen before include "Situated at the end" , "Ending in death" , "At the end, final" , "End point of circuit" , "Last, final" .)
