HONG KONG - The Hong Kong MTR Tseung Kwan O Line has been temporarily suspended this afternoon due to accumulation of water near Quarry Bay station. Photos of the affected area showed water covering both sides of the tracks and tunnel roofs reflecting in the water.
Legislative Council member Zhang Xinyu estimated that a water pipe may have burst in the tunnel, causing water accumulation, and a failure of the drainage pump made the situation worse. Still water poses a risk to train operations due to potential safety implications from floating debris.
The train service between North Point Station and Tiu Keng Leng Station is temporarily suspended. The train service between Po Lam and Tiu Keng Leng Station runs every 6 minutes, while the train between LOHAS Park and Tseung Kwan O Station runs every 12 minutes. According to the latest news from MTR, the problem has been resolved.
Zhang Xinyu said that it is not uncommon for water to accumulate in the tunnel, but according to operational regulations, services must be suspended when the water level exceeds the track height. He believes that the possibility of water accumulation is unlikely due to the intrusion of sea water due to damage to the tunnel. Instead, it is more likely that water pipes (such as fire hoses) broke inside the tunnel.
Meanwhile, the drainage pump in the tunnel failed, causing water to accumulate. The pause was necessary due to the safety hazard posed by the presence of floating debris in the water. In more severe cases, shutting off the water valves in the affected pipes can take more than an hour to clear the water.
港铁鲗鱼涌站隧道发生水浸
香港 - 由于鲗鱼涌站附近积水，香港地铁将军澳线今天下午暂停运营。 受影响地区的照片显示，铁轨两侧和隧道顶部都被水覆盖，倒影在水中。
立法会议员张新宇估计，隧道内可能有一根水管爆裂，导致积水，而排水泵故障则令情况更糟。 由于漂浮碎片的潜在安全影响，积水对列车运营构成风险。
来往北角站至调景岭站的火车服务暂停。 来往宝琳站至调景岭站的火车服务每 6 分钟一班，而来往日出康城站至将军澳站的火车服务则每 12 分钟一班。 据港铁最新消息，问题已得到解决。
张新宇表示，隧道内积水的情况并不少见，但根据运营规定，当水位超过轨道高度时必须暂停服务。 他认为，由于隧道受损导致海水侵入，积水的可能性不大。 相反，更可能的是隧道内的水管（例如消防水带）破裂。 与此同时，隧道内的排水泵发生故障，导致积水。
由于水中漂浮碎片造成安全隐患，暂停是必要的。 在更严重的情况下，关闭受影响管道中的水阀可能需要一个多小时才能清除水。
