wry

I'm a little stuck... Click here to teach me more about this clue!

'bent' is the definition.
(thesaurus)

'going west on the railway' is the wordplay.
'going west' becomes 'w' (synonyms. I am not sure about the 'going' bit.).
'on' is a charade indicator (letters next to each other).
'the railway' becomes 'ry' (abbreviation).
'w'+'ry'='WRY'

'on' acts as a link.

Can you help me to learn more?

(Other definitions for wry that I've seen before include "Of humour, dry and mocking" , "Dry and mocking, or bent out of shape" , "Drily humorous" , "Twisted; sardonic" , "Ironically humorous" .)
