Rubbish in Jerusalem rail terminus? (7)
I believe the answer is:
station
'rail terminus?' is the definition.
'rubbish in jerusalem' is the wordplay.
'rubbish' becomes 'tat' (I've seen this before).
'in' means one lot of letters goes inside another.
'jerusalem' becomes 'sion' (I've seen this in other clues).
'tat' put inside 'sion' is 'STATION'.
(Other definitions for station that I've seen before include "E.g. Waverley, Waterloo" , "Broadcasting channel" , "eg Temple Meads" , "Train halt" , "Chosen fixed point" .)
