After protest, process post in Euston maybe (7,7)
I believe the answer is:
railway station
'euston maybe' is the definition.
I can't judge whether this definition defines the answer.
'after protest process post' is the wordplay.
I cannot really see how this works, but
'protest' could be 'rail' (I've seen this before) and 'rail' is present in the answer.
'process' could be 'way' (way is a kind of process) and 'way' is present in the answer.
'post' could be 'station' (a station is a post) and 'station' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for railway station that I've seen before include "Victoria?" , "halt?" .)
