 On 9 August 1998 two rail maintenance workers, 31 and 50 years, were killed when an empty coal train rounded a sharp curve at 70 kilometres per hour (43 mph) and smashed into their truck, picking it up & spinning it into a cliff face.A third man who was on the tracks managed to leap to safety before the collision.The workers were part of 3 crews carrying out maintenance work on the Sandy Hollow-Ulan line near Muswellbrook.
