The Saxby & Farmer from at Six Mile Bottom signal box in November 1975. The two block instruments are seen above the frame. The Fulbourne - Six Mile Bottom block instrument is at the far end by the window. The Six Mile Bottom - Dullingham block instrument with the bell mounted above it is on the wall behind the track plan. The shorter levers at the far end of the frame usually controlled electrically operated equipment. the four dials above frame are the signal aspect indicators.
