Perhaps Victoria is not at fault (7)
I believe the answer is:
station
'perhaps victoria' is the definition.
(Victoria is a London train station)
'is not at fault' is the wordplay.
'fault' indicates anagramming the letters (a faulty spelling).
'is'+'not'+'at'='isnotat'
'isnotat' is an anagram of 'STATION'.
(Other definitions for station that I've seen before include "Fixed stopping place for transport" , "Place - railway stop - HQ - standing" , "eg Temple Meads" , "Put" , "Depot" .)
