FGW▸ dispatch staff (including I believe, a FGW DSM) asking why the train moved forward. She confirms what the driver says by repeating, "You've accidentally moved forward?", it then appears that she exclaims to her colleague, '******* hell." That does rather indicate that station duties were not complete and the RA not given.
WCRC really don't need to be dealing with another 'safety of the line' incident so soon after getting their licence back.
