Platform screen door (also known as screen door, English: Platform screen door(PSD) or Platform-edge door) refers to the glass curtain wall that surrounds the railway platform and the train loading and unloading space on the platform. When the train arrives at the station, open the electric door on the glass curtain wall for passengers to get on and off. The main purposes of platform screen doors are: for safety reasons, to prevent passengers from entering the track by mistake, to prevent passengers from falling off the platform and committing suicide or accidents, to save energy, to prevent the loss of air conditioning on the platform and to maintain the temperature of the platform. 1983, Lille Metro, a French automated rapid transit system, and its manufacturer Matra specially ordered automatic sliding doors for train platforms from Kaba Gilgen AG, a Swiss glass door manufacturer, which became the largest in the world. Later 1987 opened a heavy railway system, and the Singapore Metro also adopted glass screen doors. Since then, platform screen doors have been adopted in railway systems in many parts of Europe and Asia, which has become one of the safety standards of current railway systems. It is worth mentioning that as early as1960s, steel doors similar to the platform screen doors were adopted in Leningrad's subway system. In the past, people in Chinese mainland and Hongkong committed suicide by jumping off the track at the railway station (that is, jumping off the platform) or falling off the track. In addition, the power consumption of air conditioning in railway stations is staggering. For the sake of safety and environmental protection, platform screen doors have been installed in most newly-built stations in China Mainland and Hong Kong, while the subway in China Mainland and Hong Kong (now merged into MTR) is the first railway system in the world to add platform screen doors. The first stations with screen doors in China Mainland and Hongkong were the former Airport Express Line and Tung Chung Line. Platform screen doors made by Faiveley Trport have been installed in addition to new stations or platforms such as Airport Station No.3, Xinao Station and Expo Station. Since then, platform screen doors have been installed in all newly-built underground stations of the former MTR, such as the new station of Tseung Kwan O Line and the two new platforms of North Point Station, and the platform screen doors of Naboth Company were also installed during the construction period. 1997 The former MTR Corporation (now incorporated into the China-Hong Kong Railway Company Limited) invited the platform screen door manufacturers to study the feasibility of adding platform screen doors to the railway system in operation, and to build two semi-clamped tracks on the central track of Rainbow Station for testing, and to dismantle them at the later stage of testing, so as to facilitate the transfer of traffic. In June 2000, the former MTRC announced that it would add 65,438+03.5 kilometers to the existing four operating lines: Kwun Tong Line (except Yau Tong Station and Tiaojingling Station), Quarry Bay Station of Tseung Kwan O Line, Tsuen Wan Line and Hong Kong Island Line, and in 2960, it added platform screen doors to Kaba Gilgen AG, the first railway system in the world. At the same time, an additional fee of HK$ 65,438+0 was charged to Octopus passengers to raise HK$ 200 million for the construction and maintenance of platform screen doors. 200 1, the original MTRC studied the installation of screen doors in the middle rail of Rainbow Station, and then installed screen doors in major stations. The project is divided into three stages. Installation of platform screen doors was completed in June 2005165438+1October, and all related projects were completed in March 2006. At present, there are 10 former MTR ground or elevated stations (Xinghua Village Station, Chai Wan Station, Kwai Fong Station, Kwai Hing Station, Tsuen Wan Station, Kowloon Bay Station, Ngau Tau Kok Station and Kwun Tong Station) without air conditioning system and platform screen doors. The former MTRC only installed platform gates at Xin 'ao Station and Disney Station. Another predecessor of MTR, Kowloon-Canton Railway, only East Railway (now east rail line), Tsim Sha Tsui East Station and West Railway (west rail line) added platform screen doors when they built their stations. The platform screen doors they use are similar to those of the MTR Tseung Kwan O Line and are also made by Nabtesco. The platform screen door of Tsim Sha Tsui East Railway Station is the longest in the world. There are no platform screen doors at other stations of the East Rail and the later Ma 'anshan Railway (now Ma 'anshan Line). The reasons include that there is no air conditioning system on the platform. For convenience, the platform of Ma 'anshan Railway Station has been reformed. The Kowloon-Canton Railway Corporation (KCRC) has also studied the installation of platform screen doors., However, some stations have large gaps every month, and after the platform screen doors are closed, passengers may be trapped in the space between the screen doors and the platform edge. Therefore, the Kowloon-Canton Railway Company has studied the possibility of adding a platform expansion plate (the expansion plate will automatically extend to fill the gap between the train and the platform after the train arrives at the station), so the design of adding a platform screen door has not been finalized [1]. In addition to the main railway system, other railway systems also use Westinghouse's screen door in automated people mover of China Hongkong International Airport, which was opened at the same time when the airport 1998 was opened.

Since 2000, MTR has charged Octopus passengers 65,438+0 cents for the construction of subway station screen doors, and the construction cost of screen doors will reach 2 billion yuan, half of which will be paid by MTR. Since the opening of the subway, it has been found that most of the air in the station is lost in the pipeline, and people fall off the track from time to time. Therefore, the public often asks the MTRC to take measures to prevent it from falling off the track. The operation of the screen door is completely coordinated with the train control system; The conductor only needs to operate the door, and the curtain door will open accordingly; Because the train cab is equipped with CCTV monitoring platform, the conductor doesn't even need to leave the carriage.

Since 2000, MTR has collected 65,438+0 cents from Octopus passengers for the construction of screen doors in subway stations. The construction of screen doors will cost 2 billion yuan, of which one and a half will be paid by MTR. The subway should be calculated by time, with a cycle of 40 years. The extra charge for each trip is 65,438+0 cents, which can cover half the cost of the screen door project. 2008-07-1 921:29: 23 Supplement: At the meeting of the Railway Affairs Panel of the Legislative Council, the company representatives indicated that they planned to continue to charge Octopus passengers per trip1minute to support the maintenance and cleaning of screen doors. Many lawmakers criticized the subway, but when the subway proposed to increase the cost of screen doors, it did not mention that passengers should continue to bear the remaining costs, but asked the government to keep up with the subway.
