Interim arrangement for railheads (7)
I believe the answer is:
termini
'railheads' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'interim arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'interim' is an anagram of 'TERMINI'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for termini that I've seen before include "Rail stations mainly in city centres" , "Paddington, Waterloo, etc" , "End-points" , "Starting points, limits" , "End stations" .)
