Bird the train ran over (4)
I believe the answer is:
rail
This clue could be a double definition.
'bird' is the first definition.
(a wading bird)
'train ran over' is the second definition.
I know that 'train' relates to this answer.
'the' is the link.
Can you help me to learn more?
(Other definitions for rail that I've seen before include "20 backwards, that 7 runs on" , "Bird with long legs" , "Line" , "Complain bitterly - wading bird" , "Length of track" .)
