Movement of turntable perhaps derailing train too (8)
I believe the answer is:
rotation
'movement' is the definition.
(I know that rotation is a type of movement)
'turntable perhaps derailing train too' is the wordplay.
'train too' anagrams to 'ROTATION'.
However, I am not clear how this is indicated.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for rotation that I've seen before include "Revolutionary movement" , "Recurring sequence" , "Out of control" , "Turning motion" , "Spinning motion or cyclic changes as of crops" .)
