Speeding bullet finds leg bone, Anne’s knee initially shattered (10)

I believe the answer is:

shinkansen

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

'speeding bullet' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'leg bone anne's knee initially shattered' is the wordplay.
'leg bone' becomes 'shin' (shin is a kind of leg bone).
'initially' suggests taking the first letters.
'shattered' indicates an anagram.
The initial letter of 'knee' is 'k'.
'annes'+'k'='annesk'
'annesk' anagrammed gives 'kansen'.
'shin'+'kansen'='SHINKANSEN'

'finds' is the link.

Can you help me to learn more?
