A DISTRAUGHT mother who sued her husband after their son was killed in a horrific train smash won $1.5 million damages yesterday. Nine-year-old Ho Hung-hin was sitting next to his mother, Ng Yuet-lan, in the front seat of his father's van when it was hit by a Light Rail Transit (LRT) train. His brothers Hung-yiu, then aged 10, and Hung-kwong, six, sat in the seats behind. Hung-hin was thrown out of the right side window and the truck then tipped over on top of him, crushing his head. He died from skull fractures and brain damage following the crash on July 25, 1988. Ms Ng claimed she underwent a personality change following the accident which left her suicidal and led to her marriage break-up. The former shop proprietor, who is scarred for life, said she suffered from severe depression, weeping spells and lack of concentration. Doctors said Ms Ng, 37, who has since split from her husband, Ho Kit-wai, 45, would probably never fully recover. After her son's death, Ms Ng launched legal proceedings against her husband, train driver Wong Yiu-hung and the Kowloon-Canton Railway Corporation (KCRC). The case was due to begin yesterday, but the parties agreed to a $1.5 million out of court settlement at the last minute. In a High Court writ Ms Ng blamed Mr Ho and Mr Wong for negligence and not keeping a proper lookout at the LRT crossing near the Castle Peak Road and Ping Ha Road junction. She said the KCRC was also responsible for failing to employ properly experienced drivers and provide adequate supervision. The company should have installed a barrier at the crossing and required drivers to sound their horn as they approached, she said. Ms Ng who was in hospital with head and facial injuries for a week following the crash still gets headaches. Doctors said she had suffered 50 to 60 per cent physical and psychological impairment and her earning potential had been reduced by three quarters. Ms Ng who used to take home $15,000 a month from a pig farm and two other businesses in Lau Fau Shan was forced to give up almost all work after the crash. Lawyers have yet to work out how much each party will pay in the settlement. Outside court, KCRC spokesman Ida Leung said the accident happened during the line's trial period before its launch in September 1988. She strongly defended LRT safety procedures and said there had been no other problems at the junction. 'All the light rail junctions which interface with roads have traffic signals and road signs warning drivers to take care,' she said. The driver, Mr Wong, continued working after the crash, but has since left the company of his own accord. Outside court, Ms Ng said she was not happy with the settlement. 'It cannot compensate for the loss of my son,' she said. 'I will use the money to start a small business or spend it on my other sons' education.' Mr Ho was not in court.
