6月4日，方大軌道交通屏蔽門項目——香港東鐵線站台門加裝項目舉辦全線投入運作儀式，港鐵宣布比原定計劃提前約6個月完成。港鐵與政府部門包括運輸及物流局、路政署及運輸署代表出席了儀式。歷經近十年的規劃與施工，這項在正常運營鐵路線上實現「即裝即用」的站台門加裝工程正式完工，標誌着香港百年東鐵線邁入智能化、安全化的新紀元。
香港東鐵線自1910年通車以來，歷經蒸汽機車、電氣化列車到現代化過海鐵路的跨越式發展。作為香港首條連接內地口岸的鐵路，其日均客流量超百萬，承載着港深融合的重要使命。然而，部分車站站台因歷史久遠，存在間隙過大、無安全門等隱患。此次加裝工程覆蓋全線13個車站、35側月台，共安裝 1575道半高站台門及智能安全系統，全面提升乘客候車安全與舒適性。

方大是我國首批從事地鐵站台屏蔽門系統開發、設計、製造、安裝和維護的高新技術企業，主持編制了國內首部站台屏蔽門系統行業標準——《城市軌道交通站台屏蔽門》(CJ/T 236-2006)。公司擁有完整的自主知識產權的站台屏蔽門系統獲工信部製造業「單項冠軍產品」認定。方大先後在北京、上海、天津、廣州、深圳、南京、瀋陽、武漢、西安、福州、南昌、中國香港、中國台灣、新加坡、馬來西亞、哥倫比亞、印度、泰國、希臘等地承接100餘條地鐵站台屏蔽門系統工程，產品覆蓋全球43個城市。
為滿足項目「即裝即用」要求，方大團隊夜間兩小時高效施工。方大團隊需在凌晨1:30至3:30的列車停運窗口期內，完成物料運輸、門體安裝、電氣調試等全流程作業，並確保次日首班車正常運營。憑藉模塊化技術與精密管理，團隊曾創下3小時安裝調試3個單元門、4周完成整側站台（215米，45個單元門）的行業紀錄，實現「零干擾」施工，為全球軌道交通站台門工程樹立新標桿。
項目自啟動以來，從勘探設計到竣工歷時近十年，方大利用科技賦能破解複雜挑戰。精準適配站台，方大針對大學站、羅湖站等弧形月台，團隊首創「單元滑動門中心折點設計」，結合高精度測量儀器，確保相互穿插的門體開閉無干涉，攻克弧形站台和伸縮縫並存的安裝難題。有效保障安全，方大採用激光雷達技術的智能乘客探測器（PDS系統），實現站台與列車間隙無死角探測，安全等級達SIL2，有效杜絕夾人風險。克服戶外環境考驗，方大設備通過IP65防護認證，抗颱風「八號風球」級暴雨，電氣部件「盒中盒」雙重防護，電纜採用抗紫外線材料，適應香港多變氣候。場景無縫切換，方大研發高可靠性信號模擬器，在安裝期間模擬門體狀態，保障既有線路正常運行，切換時實現「零故障」過渡，確保運營與施工兩不誤。
方大香港東鐵線項目團隊。
百年東鐵，安全新生。隨着香港北環線及跨境延伸規劃推進，東鐵線將繼續發揮聯通內地與香港的樞紐作用。方大團隊此次項目的成功經驗為粵港澳大灣區和全球軌道交通站台門工程提供寶貴借鑑，推動行業技術革新。

Century-old Railway Upgraded | Hong Kong East Rail Line Platform Screen Door Installation Project Completed Six Months Ahead of Schedule, Fangda's "Install-and-Use" Technology Sets a New Benchmark for Rail Transit Safety
On June 4, Fangda's rail transit platform screen door project—the Hong Kong East Rail Line platform screen door installation project—held a ceremony for the full-line operation, with MTR Corporation announcing the project's completion approximately six months ahead of the original schedule. Representatives from MTR Corporation and government departments, including the Transport and Logistics Bureau, Highways Department, and Transport Department, attended the ceremony held. After nearly a decade of planning and construction, this platform screen door installation project, which achieved "install-and-use" on an operational railway line, is officially completed. It marks the beginning of a new era of intelligence and safety for Hong Kong's century-old East Rail Line.
Since its opening in 1910, the Hong Kong East Rail Line has undergone significant development, transitioning from steam locomotives and electrified trains to modern cross-harbor railways. As Hong Kong's first railway connecting China's mainland ports, it has a daily passenger flow exceeding one million, playing a crucial role in the integration of Hong Kong and Shenzhen. However, some station platforms, due to their historical age, have hazards such as large gaps and lack of safety doors. This installation project covers all 13 stations and 35 platforms of the line, with the installation of 1,575 half-height platform screen doors and intelligent safety systems, significantly enhancing the safety and comfort of passengers while waiting for trains.
Fangda is one of the first high-tech enterprises in China engaged in the development, design, manufacturing, installation, and maintenance of metro platform screen door systems. It led the drafting of the country's first industry standard for platform screen door systems, titled CJ/T 236-2006 Urban Rail Transit Platform Screen Doors. The company owns complete independent intellectual property rights for its platform screen door system, which has been recognized by the Ministry of Industry and Information Technology as a "single-champion product" in manufacturing. Fangda has undertaken over 100 metro platform screen door system projects in cities including Beijing, Shanghai, Tianjin, Guangzhou, Shenzhen, Nanjing, Shenyang, Wuhan, Xi'an, Fuzhou, Nanchang, Hong Kong, Taiwan, China, Singapore, Malaysia, Colombia, India, Thailand, and Greece, with its products covering 43 cities worldwide.
To meet the "install-and-use" project requirements, our team conducted efficient construction within a two-hour window at night. The team needed to complete the entire process, including material transportation, door installation, and electrical commissioning, within the train suspension window from 1:30 AM to 3:30 AM, ensuring the normal operation of the first train the following day. Using modular technology and precise management, the team set an industry record of installing and commissioning three unit doors in three hours and completing an entire platform side (215 meters, 45 unit doors) in four weeks, achieving "zero interference" construction. This has established a new benchmark for global rail transit platform door projects.
Since the project's inception, spanning nearly a decade from exploration and design to completion, Fangda has leveraged technology to overcome complex challenges. Precisely adapting to the platform, Fangda pioneered the "unit sliding door central pivot point design" for curved platforms at University Station and Lo Wu Station. This design, combined with high-precision measurement instruments, ensures non-interfering door operations, overcoming the installation challenges of curved platforms coexisting with expansion joints. To effectively ensure safety, Fangda employs an intelligent passenger detection system (PDS) utilizing LiDAR technology, achieving seamless detection of gaps between the platform and train, with a safety level reaching SIL2, effectively preventing the risk of passenger entrapment. To withstand outdoor environmental challenges, Fangda's equipment is IP65 certified, capable of withstanding typhoon-level "Storm Signal No.8" rainstorms. Electrical components are protected with a "box-in-box" design, and cables are made from UV-resistant materials, adapting to Hong Kong's variable climate. For seamless scenario transitions, Fangda developed a high-reliability signal simulator to mimic door states during installation, ensuring the normal operation of existing lines and achieving "zero-fault" transitions during switchover, ensuring both operation and construction proceed without disruption.
A century-old East Rail, safely renewed. As the planning for the Hong Kong Northern Link and cross-border extensions progresses, the East Rail Line will continue to serve as a vital hub connecting the Chinese mainland and Hong Kong. The successful experience of Fangda's project provides valuable insights for platform door projects in the Guangdong-Hong Kong-Macao Greater Bay Area and global rail transit, driving technological innovation within the industry.
