Of these, over 10 cases per year were fatal. That was the time when metro stations of the Kwun Tong Line, Tsuen Wan Line and Island Line of our railway system had not been fitted with platform screen doors (PSDs) nor automatic platform gates (APGs)1*. Nor were these stations, commissioned in the late 1970s and early 1980s, designed for the installation of safety barriers like PSDs or APGs. All new metro lines and railway lines built since 1998, including the Airport Express Line and Tung Chung Line, Tseung Kwan O Line, West Rail Line (WRL) and Disneyland Resort Line, have been fitted with either PSDs or APGs. As a result of initiatives by the Government and the MTR Corporation Limited (MTRCL), all 30 underground metro stations were retrofitted with PSDs by 2006 with the aim of enhancing platform conditions, and by 2011 all the eight above-ground metro stations of the Kwun Tong Line, Tsuen Wan Line and Island Line were also retrofitted with APGs. After completion, the annual average railway suicides and attempted suicide cases had dropped significantly to five cases in 2014, three of which were fatal.
