The Tsuen Wan line is one of the eleven lines of the metro network in Hong Kong's MTR. It is indicated in red on the MTR map.

There are 16 stations on the line. The southern terminus is Central station on Hong Kong Island and the northwestern terminus is Tsuen Wan station in the New Territories. A journey on the entire line takes 35 minutes.

As a cross-harbour route that goes through the heart of Kowloon and densely populated Sham Shui Po and Kwai Chung, the line is very heavily travelled.

History

Construction

The Tsuen Wan line was the second of the three original lines of the MTR network. The initial plan for this line is somewhat different from the current line, especially in the names and the construction characteristics of the New Territories section.

The original plan envisioned a terminus in a valley further west of the present Tsuen Wan station. That Tsuen Wan West station is different from the current Tsuen Wan West station on the Tuen Ma line, which is located under land reclaimed at a much later time. The line was supposed to run underground in Tsuen Wan rather than as currently on the ground level.

The approved route was truncated, terminating at Tsuen Wan station. The construction of the Tsuen Wan Extension project was approved in 1975 and commenced soon afterwards. Testing of the new line began on 1 March 1982.[5]

The extension was formally opened on 10 May 1982 by Sir Philip Haddon-Cave, the acting governor and former chairman of the Mass Transit Railway Provisional Authority. The project was opened seven and a half months ahead of schedule, and cost HK$3.9 billion, under budget compared to the original estimate of HK$4.1 billion.[5]

The new section from Tsuen Wan to Lai King and skipping all intermediate stations to Prince Edward opened on 10 May 1982 and joined the section under Nathan Road in Kowloon that had been in service since 1979 as part of the Kwun Tong line. On opening, Prince Edward was an interchange-only station with no option to enter or exit. It did not become a standard station until the remaining stations on the line in Sham Shui Po District, i.e. Sham Shui Po, Cheung Sha Wan, Lai Chi Kok and Mei Foo, opened a week later.

Several stations differ in names or location from the initial plan. During planning, Kwai Hing was named Kwai Chung, Kwai Fong was Lap Sap Wan (literally "rubbish bay", as the location was close to a now-disused landfill in Gin Drinker's Bay), Lai Wan (now Mei Foo) was Lai Chi Kok, Lai Chi Kok was Cheung Sha Wan, Cheung Sha Wan was So Uk. These stations were all renamed in English and Chinese before service began.

Upon the opening of the Island line, Chater, Waterloo, and Argyle, originally named based on the streets crossing or above the stations, Chater Road, Argyle Street, and Waterloo Road respectively, were renamed to Central, Yau Ma Tei, and Mong Kok, resembling the names of the station in Chinese. Lai Wan was renamed to Mei Foo in both English and Chinese.

Mong Kok station was planned to be built a bit further north of its present location and Sham Shui Po a bit further south of its present location before the need to accommodate an intermediate station, Prince Edward.

Transfer with Tung Chung line

When the Tung Chung line was constructed, Lai King was selected as an interchange so that passengers did not have to go all the way to Hong Kong Island to change trains. The northbound tracks on the Tsuen Wan line were moved to run above the southbound tracks at Lai King to support cross-platform interchange with the Tung Chung line.

The original platform 1 for Tsuen Wan-bound trains was removed and filled, becoming part of the current, wider low-level island platform. This allowed interchange with platform 4 for Hong Kong-bound Tung Chung line trains, which run on tracks further away from the original platform.

The new platform was opened in 1997, nearly a year before the Tung Chung line began service. Tracks were also built to the south of Lai King station linking the Tsuen Wan line and Tung Chung line; this is the only point where the Tung Chung line's tracks connects with the other urban lines.

Transfer with former KCR systems

To cope with extensions and new lines, Mei Foo and Tsim Sha Tsui stations had new subsurface walkways added to connect to West Rail line's Mei Foo and East Tsim Sha Tsui stations. The interchange facilities at Mei Foo opened in 2003 when the West Rail was opened. The interchange located at Tsim Sha Tsui entered service in 2004, along with the completion of the East Rail line's (formerly KCR East Rail) extension to East Tsim Sha Tsui.

Chronology

Route description

The Tsuen Wan line runs north–south. It is mostly underground, beginning at Central and crosses Victoria Harbour after Admiralty to Tsim Sha Tsui. Then, the line first runs underneath Nathan Road (Tsim Sha Tsui to Prince Edward), then Cheung Sha Wan Road (Sham Shui Po to Mei Foo), before emerging from the hills at Lai King.

The line is elevated between Lai King and Kwai Hing. Between Kwai Fong and Kwai Hing, the tracks are covered to minimise disturbance to residents nearby. After Kwai Hing, the line re-enters the tunnel to Tai Wo Hau before finally re-emerging at ground level at Tsuen Wan.

Some of the underground stations on the line are significantly deeper than the others. Tsim Sha Tsui and Admiralty stations are deeper because they precede harbour crossings. Admiralty and Central are deeper as they provide cross-platform interchange with the deep-level Island line.

Notes

  1. ^ a b Originally opened as part of the Kwun Tong line.
  2. ^ Mong Kok station is not an interchange station to Mong Kok East station on the      East Rail line in the MTR fare system. The two stations are not physically connected. There is pedestrian transfer via a footbridge; the journey time is approximately 10–15 minutes on foot.
  3. ^ Tsuen Wan station is not an interchange station to Tsuen Wan West station on the      Tuen Ma line, but green public light bus route 95K (free transfer with an immediate Tuen Ma Line journey record on the Octopus card) connects the two stations. It normally takes 15–20 minutes to walk to Tsuen Wan West station.

Central station L3
(Tsuen Wan line
terminating platform)

On 18 March 2019, two trains crashed in the crossover track section between Admiralty and Central while MTR was testing a new version of the SelTrac train control system provided by Toronto-based Canadian unit of Thales Group. There were no passengers aboard either train, although the operators of both trains were injured.[6] Before the crash site had been cleaned up, all Tsuen Wan line trains terminated at Admiralty instead of Central. Both MTR and Thales will be conducting their separate investigations. The same vendor also provided a similar signalling system in Singapore, which resulted in the Joo Koon rail accident in 2017.[7] In July 2019, the Electrical and Mechanical Services Department (EMSD) published an investigation report into the incident and concluded that a programming error in the signalling system led the ATP system to malfunction, resulting in the collision.[8]
