The Kwun Tong Line is one of the ten lines of the MTR network in Hong Kong. It starts at Yau Ma Tei in West Kowloon and ends at Tiu Keng Leng in Tseung Kwan O, Sai Kung. It is indicated in green on the MTR map. During the morning rush hour, the Kwun Tong Line utilises 27 trains on the tracks and keeps a 2.1 minute train interval. It currently travels through 15 stations in 27 minutes along its route.

History

The Kwun Tong Line was the first MTR line to enter service, and was a crucial part of the MTR "Modified Initial System". Its construction was approved in November 1975.

On 1 October 1979 service commenced on the Kwun Tong Line. The line ran between Shek Kip Mei Station and Kwun Tong Station, and each train consisted of four cars.

With extensions to the south, the line reached Tsim Sha Tsui on 31 December 1979, and a year later on 12 December 1980 it reached first Central station (named Chater at the time), crossing the harbour for the first time.

When the Tsuen Wan Line started service in May 1982, it took over the section of the Kwun Tong Line south of Argyle (present-day Mong Kok). Waterloo (present-day Yau Ma Tei) station became the terminus of the Kwun Tong Line and both Argyle and Prince Edward stations became interchange stations with the new line.

When the Hong Kong government decided to build a second harbour crossing in 1984 (which would be known as the Eastern Harbour Crossing), it awarded a franchise for the construction of a mixed rail and road tunnel under the harbour.
The Kwun Tong Line was the rail line using that tunnel and on 6 August 1989, it was extended over the harbour again. This time the terminus was Quarry Bay, a transfer station with the Island Line. An intermediate station, Lam Tin, was opened on 1 October of the same year.

As part of the Tseung Kwan O Line project, Kwun Tong Line was briefly extended to North Point on 27 September 2001 but soon diverted to Tiu Keng Leng when the Tseung Kwan O Line opened in August, 2002. The diversion was done in two phases: Yau Tong interchange station was opened on 4 August 2002 such that Kwun Tong Line did not cross the harbour anymore. Two weeks later (18 August 2002) the Kwun Tong Line was extended to Tiu Keng Leng when the rest of the Tseung Kwan O Line commenced service. While disused, the tunnel linking Kwun Tong Line to Eastern Harbour Crossing is regularly maintained and can be utilized in the event of a disruption on the Tseung Kwan O Line.^[1]

On 16 December 2013, a train on the Tseung Kwan O Line broke down, halting train services on the entire line for several hours. To prevent the cross-harbour train service from being disrupted, all Kwun Tong Line trains temporarily used the old tracks from Lam Tin to Quarry Bay, and terminated at North Point, as they did before the opening of the Tseung Kwan O Line.^[1] This was the first time since 2002 that the Lam Tin to Quarry Bay tracks were utilised for regular service.

Route description

Kwun Tong Line is mostly underground, and runs from the west to the east. It begins at Yau Ma Tei station, and runs underneath Nathan Road parallel to the Tsuen Wan Line up to Prince Edward. The line then moves east, and splits from the Tsuen Wan Line. The line then emerges after Choi Hung station, and runs on a viaduct above Kwun Tong Road between Kowloon Bay and Lam Tin Stations.

After Lam Tin station, the line travels through a tunnel in a hill and emerges above ground level at Yau Tong Station (although the line is completely covered at this point). The line also converges with the Tseung Kwan O Line. The Kwun Tong Line travels through another tunnel beneath the Tseung Kwan O cemetery before terminating at Tiu Keng Leng, located in Tseung Kwan O.

Notes

* Proposed

¹ Yau Ma Tei Station is an unannounced interchange station. Changing trains in this station lacks the convenience of cross-platform interchange in Mong Kok Station. The platforms for the █ Kwun Tong Line and █ Tsuen Wan Line in Yau Ma Tei station are on separate levels.
² Mong Kok Station is not a transfer station to the Mong Kok East Station of the █ East Rail Line, but the two stations are connected with a footbridge. Walking time is around 10–15 minutes.

Future development

The MTRC proposed to extend the Kwun Tong Line, from Yau Ma Tei to Whampoa via Ho Man Tin. The new Ho Man Tin Station will allow interchange between Kwun Tong Line and the East West Corridor of the new Sha Tin-Central Link. The extension will be completed in 2015.^[2]
