Queue to see railway being repaired? (4,2)
I believe the answer is:
line up
'queue' is the definition.
(synonyms)
'railway being repaired?' is the wordplay.
'railway' becomes 'line' (line is a kind of railway).
'being repaired?' becomes 'up' (I can't explain this - if you can you should give a lot more credence to this answer).
'line'+'up'='LINE-UP'
'to see' is the link.
Can you help me to learn more?
(Other definitions for line up that I've seen before include "Track being repaired" , "Team members" , "Array" , "Form a queue" , "identity parade" .)
