'as told by a' is the definition.
I can't judge whether this definition defines the answer.

'drunken sot on the railway?' is the wordplay.
'drunken' indicates an anagram.
'on' is a charade indicator (letters next to each other).
'the railway?' becomes 'ry' (abbreviation for railway).
'sot' anagrammed gives 'sto'.
'sto'+'ry'='STORY'
