The '''Tung Chung&nbsp;line''' ({{zh|t=東涌綫}}) is one of the ten lines of the [[MTR]] system in [[Hong Kong]], linking the town of [[Tung Chung]] with central [[Hong Kong Island|Hong Kong]]. It was built in the 1990s as part of the Airport Railway project, part of the construction of the new [[Hong Kong International Airport|Chek Lap Kok Airport]]. The line currently travels through eight stations in 31 minutes along its route. It is indicated in '''{{color|#{{rcr|MTR|Tung Chung}}|Orange}}''' on the [[MTR|MTR map]].

In October 1989, the [[Government of Hong Kong|Hong Kong government]] announced [[Airport Core Programme|plans]] to build a new airport on the island of [[Chek Lap Kok]] to replace the overcrowded [[Kai Tak International Airport]] in the heart of [[Kowloon]].<ref>{{Cite news |last=Basler |first=Barbara |last2=Times |first2=Special To the New York |date=1989-10-16 |title=INTERNATIONAL REPORT; Hong Kong Builds for the Future: Big Airport Project Is Under Way |url=https://www.nytimes.com/1989/10/16/business/international-report-hong-kong-builds-for-future-big-airport-project-under-way.html |access-date=2024-06-10 |work=The New York Times |language=en-US |issn=0362-4331}}</ref>

As part of the initiative, the government invited the MTR Corporation to build a rail link to the  [[Chek Lap Kok|new airport]]. The project initially saw opposition from the Chinese government as it feared the construction would drain the fiscal reserves of the Hong Kong government and leave the Chinese with nothing after the [[Handover of Hong Kong|British handed the territory over in 1997]].

On 16 December 2003, an open house for charity took place at the recently completed [[Nam Cheong station]], an interchange between the Tung Chung line and soon to be opened [[West Rail line]]. The station then closed on 19 December 2003 in preparation for the opening of the new KCR West Rail, and it was officially opened to public on 20 December 2003. Since then, the number of cars per train has increased from seven to eight to accommodate the additional patronage.

Between 2006 and 2007, four [[MTR Rotem EMU|new Korean Rotem Emu]] entered service to increase service frequency. The first train was delivered on 9 February 2006 and entered service on 12 June 2006. Modifications were added to the platforms to accommodate the new trains, which are a few millimetres wider than the original rolling stock.

Unlike most other railway lines in the system, the Tung Chung line travels mostly above ground and spans a greater distance. The line shares its trackage with the [[Airport Express (MTR)|Airport Express]] between [[Kowloon station (MTR)|Kowloon]] and [[Hong Kong station|Hong Kong]], [[Tsing Yi station|Tising Yi]] and [[Tung Chung East station|Tung Chung East]] and before diverging right before [[Tung Chung station]].

The line travels underground from [[Hong Kong station]] to [[Kowloon station (MTR)|Kowloon station]] across the harbour, then surfaces to the ground to reach [[Olympic station]]. Trains continue to travel above ground along the [[West Kowloon Expressway]] and stops at [[Nam Cheong station]], followed by [[Lai King station]] on a viaduct. Thereafter the line crosses the [[Rambler Channel]] and stops at [[Tsing Yi station]] on [[Tsing Yi|Tsing Yi Island]].

When [[British Hong Kong]] was planning to build the Airport Railway (Tung Chung line and Airport Express) in the 1990s, which was a few years before the [[Handover of Hong Kong|handover to China]], the Chinese government raised concerns about the effect of the project on the territory's fiscal reserves, which eventually forced the Hong Kong government to reduce the cost of the Airport Railway. The resulting changes made to the design imposed limitations on the level of service on the line.<ref>{{in lang|zh-hk}}{{cite news|author=MTR Service Update|title=為甚麼東涌綫總是班次疏落？|url=http://www.vjmedia.com.hk/articles/2012/11/26/24965|access-date=2012-11-28|date=2012-11-26}}</ref>

* The airport rail link was originally designed to accommodate four tracks, two each for the Airport Express and Tung Chung line. It was later reduced to two tracks where both services share the same trackage. As a result, signal failures can affect both services.

* The [[Lantau Link]] section of the line (consisting of the [[Tsing Ma Bridge]], [[Ma Wan Viaduct]], and [[Kap Shui Mun Bridge]]) only allows one train to pass through each direction at the same time, raising the minimum [[headway]] between trains to 2 minutes 15 seconds. As a result, some Tung Chung line trains terminate at Tsing Yi during peak hours, instead of travelling the entire line.

As a result, some Tung Chung line trains terminate at Tsing Yi during peak hours, instead of travelling the entire line.
* The signalling system is not capable of giving priority to Airport Express trains; as a result, Tung Chung line trains stopping at [[Sunny Bay station]] frequently impede Airport Express trains, which do not serve the station. Tung Chung Line trains would sometimes stop at Sunny Bay Station for an extended period of time to give way to the Airport Express trains.

* The power supply system restricts the number of trains running between Kowloon and Lai King stations. The system can accommodate a maximum of one Airport Express train and two Tung Chung trains travelling in both directions at one time. The minimum headway on this section of the line is 3 minutes 30 seconds.

The Tung Chung line (Template:Lang-zh) is one of the ten lines of the MTR system in Hong Kong, linking the town of Tung Chung with central Hong Kong. It was built in the 1990s as part of the Airport Railway project, part of the construction of the new Chek Lap Kok Airport. The line currently travels through eight stations in 31 minutes along its route.

History

In October 1989, the Hong Kong government announced plans to build a new airport on the island of Chek Lap Kok to replace the overcrowded Kai Tak International Airport in the heart of Kowloon.[1]

As part of the initiative, the government invited the MTR Corporation to build a rail link to the new airport. The project initially saw opposition from the Chinese government as it feared the construction would drain the fiscal reserves of the Hong Kong government and leave the Chinese with nothing after the British handed the territory over in 1997.

Both the Chinese and British governments reached an agreement and construction commenced in November 1994. The line was originally named Lantau line but was later renamed Tung Chung line during the construction.

The Lantau Airport rail link consists of two train lines, the Tung Chung line and the Airport Express. Both lines deploy the same rolling stock with differences in interior fittings and liveries. The Lantau Airport Railway had consultants such as Arup, Halcrow, Meinhardt, Hyder Consulting, and others, at the time of the construction.[2]

On 22 June 1998, the Tung Chung line was officially opened by Chief Executive Tung Chee-hwa, and service commenced the next day.[3]

On 16 December 2003, an open house for charity took place at the recently completed Nam Cheong station, an interchange between the Tung Chung line and soon to be opened West Rail line. The station then closed on 19 December 2003 in preparation for the opening of the new KCR West Rail, and it was officially opened to public on 20 December 2003. Since then, the number of cars per train has increased from seven to eight to accommodate the additional patronage.

Sunny Bay station opened on 1 June 2005 as an interchange for the Disneyland Resort line. The resort opened its doors two months after the station became operational.

Between 2006 and 2007, four new Korean Rotem Emu entered service to increase service frequency. The first train was delivered on 9 February 2006 and entered service on 12 June 2006. Modifications were added to the platforms to accommodate the new trains, which are a few millimetres wider than the original rolling stock.

Route description

Unlike most other railway lines in the system, the Tung Chung line travels mostly above ground and spans a greater distance. The line shares its trackage with the Airport Express between Kowloon and Hong Kong, Tsing Yi and Tung Chung East and before diverging right before Tung Chung station.

The line travels underground from Hong Kong station to Kowloon station across the harbour, then surfaces to the ground to reach Olympic station. Trains continue to travel above ground along the West Kowloon Expressway and stops at Nam Cheong station, followed by Lai King station on a viaduct. Thereafter the line crosses the Rambler Channel and stops at Tsing Yi station on Tsing Yi Island.

Trains then enter a tunnel through the hills of the island and continues on the Tsing Ma Bridge and the Kap Shui Mun Bridge onto Lantau Island. The line continues along the North Lantau Expressway and stops at Sunny Bay before terminating at Tung Chung. The distance between the two stops is roughly Template:Cvt and takes approximately 6 minutes to complete.

Some outbound peak trains do not continue to Lantau but terminate at Tsing Yi station instead due to less passengers continuing towards Tung Chung and the capacity constraint of the Tsing Ma Bridge which only allows one train per track every two and a half minutes.[4]

Design limitations

When British Hong Kong was planning to build the Airport Railway (Tung Chung line and Airport Express) in the 1990s, which was a few years before the handover to China, the Chinese government raised concerns about the effect of the project on the territory's fiscal reserves, which eventually forced the Hong Kong government to reduce the cost of the Airport Railway. The resulting changes made to the design imposed limitations on the level of service on the line.[5]

  • The airport rail link was originally designed to accommodate four tracks, two each for the Airport Express and Tung Chung line. It was later reduced to two tracks where both services share the same trackage in some sections. As a result, signal failures can affect both services.
  • The Lantau Link section of the line (consisting of the Tsing Ma Bridge, Ma Wan Viaduct, and Kap Shui Mun Bridge) only allows one train to pass through each direction at the same time, raising the minimum headway between trains to 2 minutes 15 seconds. As a result, some Tung Chung line trains terminate at Tsing Yi during peak hours, instead of travelling the entire line.
  • The signalling system is not capable of giving priority to Airport Express trains; as a result, Tung Chung line trains stopping at Sunny Bay station sometimes impede Airport Express trains, which do not serve the station. Tung Chung Line trains would sometimes stop at Sunny Bay Station for an extended period of time to give way to the Airport Express trains.
  • The power supply system restricts the number of trains running between Kowloon and Lai King stations. The system can accommodate a maximum of one Airport Express train and two Tung Chung trains travelling in both directions at one time. The minimum headway on this section of the line is 3 minutes 30 seconds.

Future development

Extension in Tung Chung

Tung Chung line extension

In the Railway Development Strategy 2014, it was proposed that the Tung Chung Line be extended west and a new station constructed at Tung Chung West.[6]

In April 2020, Carrie Lam and the Executive Council approved the detailed planning and design of the Tung Chung line extension project consisting of two new stations. Construction began in May 2023, with the cost of the two new stations expected to be HK$24.2 billion in 2023. Template:Stn is an infill station between Template:Stn and Template:Stn, while Template:Stn would be a new underground station west of Tung Chung and serve as the new terminus of the Tung Chung Line.[7] This extension is expected to be complete by 2029. The project is will extend the line by an additional 1.3 kilometres. The design contract for the extension was awarded to British engineering companies Arup and Atkins in June 2021.[8][9]

Extensions on Hong Kong Island

Airport Railway Extended Overrun Tunnel (AREOT)

An underground tunnel, around half a kilometer long, will be built eastwards of Hong Kong station. It will allow Tung Chung line and Airport Express trains to turn around so trains can easily switch directions and enhancing operational efficiency. This project would also include the construction of a new ventilation building, ARB. Construction is expected to begin in 2025 and to be completed by 2032.[10][11]

North Island line

Script error: No such module "Labelled list hatnote".

Once the North Island line is complete, trains will travel in a tunnel east of Hong Kong station along the shore of the island before reaching Tamar, also connecting with the Tseung Kwan O line as an interchange. Three new stations – Tamar, Exhibition Centre and Causeway Bay North will form part of the extension. As of 2025, the government has stated that the extension isn't of high demand, and will not be completed before 2046.[12]
