I disembarked trains to design junction relocation (10)
I believe the answer is:
transplant
'relocation' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'i disembarked trains to design junction' is the wordplay.
I cannot quite see how this works, but
'i' could be 'a' and 'a' is present in the answer.
'design' could be 'plan' (synonyms) and 'plan' is present in the answer.
'junction' could be 't' and 't' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for transplant that I've seen before include "Change of heart" , "Transfer to another situation" , "Remove into new bed (or body?)" , "Move from place to place" , "Lift and reset in another soil or situation" .)
