Tseung Kwan O station into two branches, one northward to
Po Lam and one southward to
LOHAS Park. The Tseung Kwan O Depot at
LOHAS 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.

s. It was the only line with tracks completely in tunnels until the completion of
LOHAS Park station, which there are two short sections nearby that are not in tunnels. The stations of
Yau Tong,
Po Lam and
LOHAS 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 is

. From Yau Tong, the line passes through the
Black Hill Tunnels to enter
Tseung Kwan O New Town at
Tiu Keng Leng.
Within Tseung Kwan O new town, the line splits into two branches east of
Tseung Kwan O station. One branch reaches
Hang Hau and
Po Lam stations in the northern part of the new town, whereas the southward branch connects
LOHAS Park station in Area 86.
LOHAS Park is a large residential development built above the
Tseung Kwan O Depot, where the trains of the line are maintained.
Train operations

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 during
rush hour; during non-peak periods, LOHAS Park is only served by "shuttle trains" that terminate at
Tiu Keng Leng, operating at 12-minute intervals. Passengers travelling to and from LOHAS Park during non-peak hours are required to change trains at
Tiu Keng Leng or
Tseung 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
History
The Tseung Kwan O line was planned to serve the new town of
Tseung Kwan O and was first proposed in 1981 as part of the ''Junk Bay New Town Transport Study''. The report proposed four corridors, all of which called for the
Kwun Tong line to be extended to
Lam Tin station and placed the terminus of the Tseung Kwan O line at the vicinity of
Tsui Ping Estate. The construction cost was estimated at HK$3 billion. The construction of the Tseung Kwan O line was approved by the
Hong Kong Government
The Government of the Hong Kong Special Administrative Region (commonly known as the Hong Kong Government or HKSAR Government) is the Executive (government), executive authorities of Hong Kong. It was established on 1 July 1997, following the ...
in 1985 and under the 1985 plan, a branch line from Lam Tin station to
Tseung Kwan O station, consisting of 5 or 6 stations, was to be built beginning in 1992 and to open by the end of 1996.
This plan was cancelled by the MTR Corporation in August 1990.
MTR re-proposed the line in 1993, and the plan was approved by the
Hong 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. The new line took over the cross-harbour segment, via the

Yau Tong and
Tiu Keng Leng stations to interchange with the new line.

, 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.

to
Kennedy 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.
