Unusually, Sapperton Tunnel has short open section part the way along its length. This is conveniently situated near a main road, and until the rampant vegetation growth of recent years it was possible take a picture as a train emerged from the long (1864 yards) tunnel, and just before it disappeared into the short (352 yard) tunnel. On 4 September 1983 B426 (51406, 59516 & out of sight in the tunnel, 51364) emerges briefly into the light with the 16:30 Cheltenham to Swindon service.
