TheTseung Kwan O line (Chinese:將軍澳綫) is one of the ten lines of theMTR system inHong Kong. It is currently 12.3 kilometres (7.6 mi) long, taking 15 minutes to travel throughout the entire line. It is indicated inPurple on theMTR map.

The line runs fromNorth Point on theHong Kong Island to thenew town ofTseung Kwan O. It bifurcates east ofTseung Kwan O station into two branches, one northward toPo Lam and one southward toLOHAS Park. The Tseung Kwan O Depot atLOHAS Park is responsible for the maintenance of the line's rolling stock.

During the morning peak period, the Tseung Kwan O line uses 15 trains to maintain a frequency of 2.5 minutes between Tseung Kwan O and North Point.

The Tseung Kwan O line is the first MTR line with no tracks onviaducts and is the only line without Automatic Platform Gates prior to the opening of theWest Rail line which is now theTuen Ma line. It was the only line with tracks completely in tunnels until the completion ofLOHAS Park station, which there are two short sections nearby that are not in tunnels. The stations ofYau Tong,Po Lam andLOHAS Park are at ground level, but are completely shielded to minimise noise to the surrounding development. The rest of the line has its tracks located underground.

The western terminus of the line isNorth Point, providingcross-platform interchange with theIsland line. However, the next station,Quarry Bay, still interchanges with the Island Line but does not provide such a cross-platform interchange. East of Quarry Bay, the line passes underVictoria Harbour toYau Tong station, a station servingthe East Kowloon neighbourhood of the same name, using the rail tunnel of theEastern Harbour Crossing. From Yau Tong, the line passes through theBlack Hill Tunnels to enterTseung Kwan O New Town atTiu Keng Leng.

Within Tseung Kwan O new town, the line splits into two branches east ofTseung Kwan O station. One branch reachesHang Hau andPo Lam stations in the northern part of the new town, whereas the southward branch connectsLOHAS Park station in Area 86.LOHAS Park is a large residential development built above theTseung Kwan O Depot, where the trains of the line are maintained.

Operation of the line is relatively complex because of the split into two branches at Tseung Kwan O.

The majority of trains on the line run through from Po Lam to North Point and vice versa. Through service between LOHAS Park and North Point is only provided duringrush hour; during non-peak periods, LOHAS Park is only served by "shuttle trains" that terminate atTiu Keng Leng, operating at 12-minute intervals. Passengers travelling to and from LOHAS Park during non-peak hours are required to change trains atTiu Keng Leng orTseung Kwan O in order to continue their journey.

Train headways are as follows:

• Rush hour: One through train to/from LOHAS Park after two trains to/from Po Lam
  • North Point - Po Lam trains: every 2.5 or 4 minutes
  • North Point - LOHAS Park trains: every 7–8 minutes
  • combined headway between North Point and Tseung Kwan O is 2.5 minutes.
• Non-peak period:
  • Mon-Fri, Sat (10:00-20:00) and Sun (09:00-20:00)
    • North Point - Po Lam trains: every 4 minutes
    • Tiu Keng Leng - LOHAS Park shuttle trains: every 12 minutes
    • No through service from LOHAS Park to North Point, vice versa
  • Every day between 20:00 and 00:00
    • North Point - Po Lam trains: every 5 minutes
    • Tiu Keng Leng - LOHAS Park shuttle trains: every 12 minutes
    • No through service from LOHAS Park to North Point, vice versa
  • Every day after 00:00
    • North Point to Po Lam trains: every 6 minutes
    • Po Lam to North Point trains: every 8–9 minutes
    • Tiu Keng Leng - LOHAS Park shuttle trains: every 12 minutes

The Tseung Kwan O line was planned to serve the new town ofTseung Kwan O and was first proposed in 1981 as part of theJunk Bay New Town Transport Study.^[4] The report proposed four corridors, all of which called for theKwun Tong line to be extended toLam Tin station and placed the terminus of the Tseung Kwan O line at the vicinity ofTsui Ping Estate.^[5] The construction cost was estimated at HK$3 billion.^[6] The construction of the Tseung Kwan O line was approved by theHong Kong Government in 1985 and under the 1985 plan, a 7 km (4.3 mi) branch line from Lam Tin station toTseung Kwan O station, consisting of 5 or 6 stations, was to be built beginning in 1992 and to open by the end of 1996.^[7] This plan was cancelled by the MTR Corporation in August 1990.^[8]

MTR re-proposed the line in 1993, and the plan was approved by theHong Kong Executive Council on 20 October 1998. Construction commenced on 24 April 1999 and the line opened on 18 August 2002, at a cost of HK$18 billion.^[9] The new line took over the cross-harbour segment, via theEastern Harbour Crossing toNorth Point station, from theKwun Tong line. The Kwun Tong line was extended toYau Tong andTiu Keng Leng stations to interchange with the new line.

The line is served by theK-Stock andM-Trains. The K-Stock trains were manufactured by a consortium ofHyundai Rotem andMitsubishi Corporation, and were expected to be quieter and to use energy generated from deceleration.

Although tailor-made for the line, the K-Stock trains actually ran on the Kwun Tong line temporarily from launch through April 2010, and the original M-Trains ran on this line instead. The K-Stock trains were finally transferred to this line in April 2010.

The Tseung Kwan O line will probably be extended toTamar station and interchange with an extendedTung Chung line there. This is according to the "interchange scheme" devised for theNorth Island line, which would also see the line serve stations atFortress Hill,Causeway Bay North andExhibition Centre, the latter of which would provide a connection with theSha Tin to Central Link extension of theNorth South Corridor (East Rail Line to Admiralty). Construction is not expected to begin before 2021.

Under an earlier proposal, called the "swap scheme", the line would have taken over the section of the Island line fromFortress Hill toKennedy Town; with the remaining section east of Tin Hau being transferred to the Tung Chung line. This was rejected as the existing Island line would be interrupted and require an interchange.

In the Chief Executive's 2022 Policy Address, it was announced that the Tseung Kwan O line would be extended southwards to Tseung Kwan O Area 137, an 80 hectare plot of land the Development Bureau has identified suitable for the development of 50,000 new housing units. Area 137 is expected to take in new populations in 2030, but there has been no expected timeline for the completion of the extensions or the opening of the new station.^[10][11]
