Anxious to get the fare, depending on going by railway (6)
I believe the answer is:
hungry
'anxious to get the fare depending' is the definition.
I can't tell whether this defines the answer.
'on going by railway' is the wordplay.
'on going' becomes 'hung' (I can't explain this - if you can you should give a lot more credence to this answer).
'by' is a charade indicator (letters next to each other).
'railway' becomes 'ry' (abbreviation for railway).
'hung'+'ry'='HUNGRY'
Can you help me to learn more?
(Other definitions for hungry that I've seen before include "Wanting fare" , "Craving food" , "Empty" , "Desirous" , "Keen" .)
