Following up to the question raised at the council meeting on16 . 12 . 98 , hon leung yiu - chung raised a question on safety of passengers on mtr platforms , particularly about mtrc s plans to install retrofitting platform screen doors on all platforms of underground stations 为跟进在1998年12月16日立法会会议上提出的质询，梁耀忠议员就乘客在地铁月台的安全问题，尤其是地铁在所有地下车站加装月台幕门的计划提出质询。
As at end - december 2004 , the contribution of ten cents for each octopus passenger trip collected by the mtr corporation limited ( mtrcl ) since july 2000 totalled about $ 0 . 3 billion for funding the corporation s $ 2 billion programme to retrofit platform screen doors ( psds ) at mtr stations 地铁有限公司（地铁公司）自二年七月起向持八达通卡地铁乘客收取每程港币一毫的费用以资助其二十亿港元的地铁月台幕门加装计划。
According to mtr corporation limited ( mtrcl ) , the project cost of the retrofitting of platform screen doors ( psds ) at 74 platforms in all 30 underground mtr stations is over $ 2 billion , that is about $ 2 . 7 million for the retrofitting works at each platform 根据地铁有限公司(地铁公司)提供的资料，地铁全?三十个地底车站共七十四个月台的月台幕门加装工程费用共超过二十亿港元，即平均每个月台的工程开支需要约二百七十万港元。
Csrp then sought the information from the environment , transport and works bureau " etwb " but etwb , citing paragraph 2 . 15 of the code on access to information , rejected the request on the grounds that the public interest i . e . the cost - effectiveness of installing platform screen doors in disclosure did not outweigh the harm that would result in the individuals privacy 研究中心其后向环境运输及工务局下称"环运局"索取有关资料，但环运局引用公开资料守则第2 . 15段，以披露资料的公众利益即安装月台幕门的成本效益不超过披露资料对个人私隐所造成的伤害为理由，拒绝了有关要求。
Given that the mtr corporation limited " mtrcl " has been charging an extra 0 . 1 for each mtr octopus journey since july 2000 to fund the platform screen door retrofit programme , will the government inform this council whether it knows the total amount of extra fares which has been paid by mtr passengers so far 鉴于地铁有限公司自2000年7月起向使用八达通卡的乘客收取每程一毫的额外收费，以资助其加装月台幕门计划，政府可否告知本会，是否知悉地铁乘客至今所缴额外收费总额？
For the remaining eight at - gradeoverhead stations ( tseun wan , kwai hing , kwai fong , ngau tau kok , kowloon bay , kwun tong , heng fa chuen and chai wan ) , retrofitting of platform screen doors involves major alterations to the stations and tunnel ventilation , air - conditioning and smoke extract systems . since such at - gradeoverhead stations are not designed with air - conditioning and ventilation systems , retrofitting works are subject to technical constraints 至于其馀8个现时没有月台幕门的地面及高架车站（即荃湾、葵兴、葵芳、牛头角、九龙湾、观塘、杏花?及柴湾） ，加装月台幕门系统须涉及重大工程，包括车站及隧道通风系统、冷气系统及抽风系统等的大型修改工程。
