The Commissioner for Transport has urged transport companies to pay more attention to workers' health after an MTR train driver collapsed in his cab and died on Friday. Wong Yuk-wing, 49, fell unconscious at the controls as the train arrived at Tai Wo Hau station from Tuen Mun. A member of staff there investigated after the doors did not open. Passengers were never at risk as the trains are run automatically by computer. A postmortem examination is being carried out on Wong. The commissioner, Robert Footman, said companies should pay more attention to scheduling and to the health of drivers. A spokeswoman for the Mass Transit Railway Corporation said Wong's family would be compensated according to labour laws. Wong had just returned to work after a three-day holiday and was described by colleagues as healthy and happy.
