The appellants were security guards employed by Kuffs Security Services CC and deployed to patrol electric cables along Metrorail’s railway lines between Cape Town and Woodstock. On the night of 3 February 2002, after scheduled train services had ended, they were patrolling near the tracks when Metrorail dispatched an unscheduled train for repairs without warning them. The train, driven by Mr Human, approached from behind in dark and windy conditions. Despite sounding the siren and braking, the train struck both appellants, causing serious injuries, including brain damage to the first appellant. The appellants sued Metrorail and the driver for negligence. Metrorail joined Kuffs as a third party based on an indemnity agreement.
