One unconscious of crossing the railroad track? (7)
I believe the answer is:
sleeper
This might be a double definition.
'one unconscious of crossing' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'railroad track?' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'the' is the link.
Can you help me to learn more?
(Other definitions for sleeper that I've seen before include "Unactivated spy - railway support" , "Rip Van Winkle" , "Beam across railway track or berth on ship" , "Rail supporter; secret agent" , "Railbed block; railway car" .)
