悉尼备受期待的地铁延伸线将于下周五开通，为该市西南部居民结束了长达两年多的替代巴士服务。
A long-awaited extension to Sydney's metro line will open on Friday next week, bringing an end to more than two years of replacement buses for residents in the city's south-west.
新南威尔士州州长克里斯·明斯周四上午在Instagram上发布视频宣布，西南地铁延伸线将于10月30日周五开通。政府在一份声明中表示，首班服务将于凌晨4时31分开始运行。
In a video shared on Instagram on Thursday morning, the New South Wales premier, Chris Minns, announced that the south-west metro extension would open on Friday 30 October. In a statement, the government said the first service would commence at 4.31am.
明斯感谢“成千上万的通勤者、家庭和当地企业在我们进行这项重大改造期间的耐心等待。”他说：“这是悉尼西南部的一个重要时刻。”
Minns thanked "the thousands of commuters, families and local businesses for their patience while we've undertaken this major transformation." "This is a huge moment for south-west Sydney," he said.
此前，原T3重轨线路于2024年9月关闭，以便改造为无人驾驶快速交通系统，距今已逾两年。该线路曾服务于悉尼内西部和西南部的10个车站——马里克维尔、德尔维奇山、赫尔斯通公园、坎特伯雷、坎普西、贝尔莫尔、莱肯巴、怀利公园、潘奇堡和班克斯敦。
It comes more than two years after the former T3 heavy rail line, which serviced 10 stations in Sydney's inner west and south west – Marrickville, Dulwich Hill, Hurlstone Park, Canterbury, Campsie, Belmore, Lakemba, Wiley Park, Punchbowl and Bankstown – closed in September 2024 to be converted to the driverless rapid transit system.
从周五起，一条全长66公里的连续地铁线路将从城市西北部的塔拉旺经中央商务区延伸至西南部的班克斯敦。
A continuous 66km metro line will span from Tallawong in the city's north-west through the CBD to Bankstown in the south-west from Friday.
在监管机构批准延误导致城市地铁段2024年开通日期推迟后，明斯政府一直避免为西南延伸线承诺具体日期，尽管媒体报道称其原定目标为10月18日开通。
After regulator approval delayed the opening date of the city metro section in 2024, the Minns government had been at pains not to commit to a date for the south-west extension, despite media reports that it was aiming for launch on 18 October.
上周，交通部长约翰·格雷厄姆表示，开通“非常接近”，只是“几周而非几个月”的问题，此前运营方悉尼地铁已向国家铁路安全监管办公室（ONRSR）提交了最后一份安全数据。
Last week, the transport minister, John Graham, said that the opening was "very close" and "a matter of weeks, not months" after the operator, Sydney Metro, provided the final piece of safety data to the Office of the National Rail Safety Regulator (ONRSR).
该项目旨在将这些车站与于2024年8月开通的城市地铁相连，当时预计耗时12个月。在此期间，通勤者不得不乘坐粉色替代巴士在目前的终点站赛登汉姆换乘地铁服务。
The project to connect the stations to the city metro, which opened in August 2024, was estimated to take 12 months at that time. In the interim, commuters have had to use pink replacement buses to connect to metro services at Sydenham, where the line currently terminates.
政府表示，这些粉色外观的替代巴士将在10月30日及首次运营的周末继续正常运行。
The government says the pink rail replacement buses will continue to operate on 30 October and the first weekend of operation.
该地铁线路开通后，从班克斯敦到中央区的行程预计只需28分钟，比原有的重轨线路节省了6分钟的时间。对于距离更长的路线（例如从莱克姆巴到维多利亚十字的行程），预计节省的时间会更多——全程仅需37分钟，比之前的出行时间缩短了24分钟。
When the line opens, a journey from Bankstown to Central is expected to take 28 minutes – a six-minute saving compared with the former heavy rail line. Longer journeys are expected to yield greater savings, such as Lakemba to Victoria Cross, which will take 37 minutes – a 24-minute saving on previous travel times.
政府称，这一扩建工程将使高峰时段的运能增加1.7万人。在高峰时段，地铁列车每4分钟一班；白天每5分钟一班；而在晚上和周末则每10分钟一班。
The government says the extension will deliver capacity for an additional 17,000 people during peak hours. Metro services run every four minutes during peak hours, five minutes during the day, and 10 minutes in the evenings and on weekends.
由于在改造这条已有130年历史的重轨线路及相关车站时遇到了诸多挑战（例如需要安装机械装置来填补弯曲站台与列车之间的空隙），该项目曾多次延期。
The project has been delayed amid challenges in converting the 130-year-old heavy rail line and historic stations, including the need to add mechanical "gap-fillers" to fill spaces between curved platforms and trains.
当西南部地铁线路正式开通后，该线路上的360扇车门中有6扇将暂时无法使用（其中3扇位于德威奇山站，另外3扇分别位于马里克维尔站、坎特伯雷站和坎普西站）。这些车门将在收集相关数据以评估这些机械装置的可靠性期间被暂时关闭。
When the south-west metro opens, six of the 360 doors on the line where gaps are widest – three doors at Dulwich Hill, and one each at Marrickville, Canterbury and Campsie – will not be in use while data is collected on the reliability of the gap-fillers.
该项目最初由前联合政府于2014年宣布。工党在2019年的选举中反对该计划，但在明斯于2023年成为总理后承诺完成该工程。由于施工过程中出现诸多问题，整个项目的总成本预计将超过200亿澳元。
The project was first announced by the former Coalition government in 2014. Labor campaigned against it at the 2019 election but committed to completing it after Minns became premier in 2023. Amid blowouts, the city and south-west metro sections are expected to cost more than $20bn combined.
