Bristol-controlled signal B384 protects the entrance to Weston-super-Mare station from the east. The 'feathers' are showing that the route has been set into platform 1; a position light signal and theatre indicator below the main signal head were provided when the signal was commissioned in the 1970s to allow locomotives to run around their trains in the station, a move that is seldom required nowadays.
