'into siding' is the definition.
I can't judge whether this defines the answer.

'terrible end thus' is the wordplay.
'terrible' is an anagram indicator.
'end'+'thus'='endthus'
'endthus' with letters rearranged gives 'SHUNTED'.

'put' acts as a link.

Can you help me to learn more?

(Other definitions for shunted that I've seen before include "Moved to one side" , "Moved aside" .)
