Signal W111, a filament-bulb four-aspect signal installed in the 1980s. It controls movements in the up direction from platform 3. Straight ahead is the route via Trowbridge to Bristol (or Swindon); the right-hand 'feathers' are for trains heading east towards London. There are two 'stencils' to give more specific route information above the two small lamps of a calling-on signal which gives permission for shunting moves.
