'fair diversion' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'leading straight on to crash?' is the wordplay.
'leading' says to put letters next to each other.
'to crash?' is an anagram indicator (I've seen 'crash' mean this).
'straight' after 'on' is 'onstraight'.
'onstraight' with letters rearranged gives 'GHOST TRAIN'.

Can you help me to learn more?

(Other definitions for ghost train that I've seen before include "Fairground attraction" , "Spooky ride" , "funfair ride" , "scary ride" .)

I've seen this clue in The Independent.
