The two appellants were security guards employed by Kuffs Security Services CC, contracted to provide services to Transnet Limited trading as Metrorail. On 3 February 2002 at approximately 22h45, the appellants were patrolling electric cables between Cape Town Station and Woodstock station as part of their duties. There were no scheduled trains after 22h00 and suburban rail services did not operate until 04h00 the next morning. Metrorail sent an unscheduled train down the line from Cape Town to Salt River for repairs without warning the appellants. The train was driven by Metrorail's employee, Mr Human (the second respondent). Human saw two figures walking on the line, sounded the train's siren, and when he received no reaction, applied the brakes. It was too late and the train struck both appellants from behind, causing serious injuries including brain damage to the first appellant requiring the appointment of a curator ad litem. The night was dark with a strong south-easterly wind blowing in the appellants' faces as they walked toward Woodstock. The appellants had been led to believe, based on their training and experience, that no trains ran after 22h00.
