'bloody' is the definition.
(similar in meaning)

'journey by rail' is the wordplay.
'journey' becomes 'go' (I've seen this in other clues).
'by' is a charade indicator (letters next to each other).
'rail' becomes 'ry' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'go'+'ry'='GORY'

Can you help me to learn more?

(Other definitions for gory that I've seen before include "Covered in blood" , "Maybe gruesome" , "Bloodstained" , "Grisly" , "Involving much bloodshed" .)

I've seen this clue in The Sun.
