The South Island Line is the first new MTR line to open to revenue service after the Rail merger. It is also the first public transport railway line in the Southern District. It is positioned with "auxiliary traffic" as a route to and from Admiralty in the Central and Western Districts of Hong Kong Island. The station and South Horizons Station, Ap Lei Chau, have a total length of about 7.4 kilometers, with 5 stations, using Chinese-made driverless trains, and the cost is about 16.9 billion HKD.

The South Island Line, known as the "South Island Line (East)" during the planning-to-construction period, commenced construction on 8 July 2011; as for the South Island Line (West), to and from Wong Chuk Hang via Pok Fu Lam to HKU Station, the construction schedule has not yet been finalized as of now.

On the eve of the opening of the South Island Line (East), the MTR decided to drop the word "East" and simply call it "South Island Line". It opened to revenue service on December 28, 2016. Since then, the Southern District has also been included in the MTR network and thus covering all 18 districts in Hong Kong. On the route map, the South Island Line is represented by colour light green; this line is named after the Southern District of Hong Kong Island that it serves.

## Original proposal

### Route and stations

The MTR Corporation Limited (MTRC) submitted its first proposal for the South Island line in May 2002. The new line was intended to be included in a promotion to promote tourism in Aberdeen. The West Island line is an extension of the Island Line.

The South Island Line is a semicircular line with nine stations. The South Island Line is intended to serve the southern end of Hong Kong Island towards Aberdeen. It interchanges with the Island Line at University and at Wan Chai. From University to Wan Chai, the other stations on the line are Cyberport, Wah Fu, South Horizons, Lei Tung, Wong Chuk Hang, Ocean Park, and Happy Valley.

On 21 January 2003, the Executive Council of Hong Kong made modifications on the South Island Line project to achieve a more cost effective option and the parallel development of Route 4. However, the first proposal has some major drawbacks. Specifically, construction of West Island Line as heavy railway type tunnels and stations would not include Kennedy Town if there is no Western reclamation. There would also be great environmental impact and traffic management challenge if West Island Line goes under Des Voeux Road West. There would not be an Aberdeen station for serving the Aberdeen area. Transfer station at Wan Chai does not cater well for the needs of cross harbour trips (they must change to Island Line heading Admiralty and another change to Tsuen Wan Line for cross-harbour trains).

## Preliminary scheme

In order to respond to the criticism directed towards the original proposal, the MTRC started a feasibility study of the lines in mid-2003 to look for cost effective options to improve the system. The study also evaluated the external benefits of the project and its impact on other modes of public transport. The company derived a modified proposal in November 2003, with three options of alignment in the South Island Line part, to address the drawbacks in the initial scheme.

### Alignment and stations

The western section of the South Island Line was transferred to the West Island Line. The South Island Line will be a medium capacity system.

Option A alignment - from South Horizons to Admiralty

* South Horizons
* Lei Tung
* Wong Chuk Hang (Interchange to West Island Line)
* Ocean Park
* Happy Valley
* Wan Chai (Interchange to Island Line)
* Admiralty (Interchange to Tsuen Wan Line & Island Line)

### Alignment options of South Island Line

Three alignment options of South Island Line:

* **Option A**: Ocean Park > Happy Valley > Wan Chai > Admiralty

This alignment is the most expensive, but has the greatest catchment.
* **Option B**: Ocean Park > Admiralty (no intermediate station)

1. Reduces travel times from Southern District to CBD.
2. Least expensive option.

* **Option C**: Ocean Park > Admiralty (> Wan Chai > Happy Valley)

Similar to option B, but enables further extension to Happy Valley in the future.
## Revised alignment scheme

### Alignment and stations

The corporation handed in the Revised Alignment Scheme in March 2004. South Island Line runs from South Horizons to Admiralty in the scheme, still having three alignment options.

* South Horizons
* Lei Tung
* Wong Chuk Hang (Interchange to West Island Line)
* Ocean Park
* Happy Valley (*Option B, C*)
* Wan Chai (Interchange to Island Line) (*Option C*)
* Admiralty (Interchange to Tsuen Wan Line & Island Line) (*Option A, B, C*)

A depot will be built in the area of Wong Chuk Hang Estate, just next to Wong Chuk Hang station.

### Interchange stations

The above scheme has interchanges at Sai Ying Pun, Wong Chuk Hang, Admiralty and probably Wan Chai. They have the following characteristics to enhance transfers:

**Sai Ying Pun**

West Island Line on upper island platform, Island Line on lower island platform. Transfer by short escalator ride.
**Wong Chuk Hang**

Double island platform with three tracks. South Island Line (West Section) trains uses the center track while South Island Line (East Section) trains use those on the two sides. Convenient cross-platform transfer can be made in both directions.
**Admiralty**

A new island platform will be built under Queensway. Two 100 metre transfer passages are built to connect the new station with existing station. Shortened transfer time can be made possible by installing escalators and conveyors. Possible passages can be built to connect the to the platforms of the Sha Tin to Central Link rail project.
### Construction method

Most of the sections including stations will be underground. The alignment across Cyberport and the segment along the nullah of Wong Chuk Hang will be on a viaduct. Survey Management of the casting of the viaducts is being conducted by Jars Land Surveyors. A new bridge alongside the Ap Lei Chau Bridge will also be built.

More detailed construction methods on the running track and stations can be found here.

### Rail system

A medium capacity system will be used. The rolling stock can be steel wheel over steel rail, similar to what MTR and KCR lines used. Rubber-tyred stock is more common in medium systems, and more flexible to decide the alignment of the rail lines as they can run on steep gradients and tight curves.

New 60-meter long trains running on rubber tyres with a frequency between two and four minutes could meet the predicted ridership. Stations on the new lines can be shorter than heavy rail stations.

### Construction cost

According to the summary report of the new lines, the construction cost including West and South Island Lines is between HK$14.6-16.5 billion. MTR has asked for government funding of less than half of the total cost. The remaining cost and the operational cost will be covered by MTR.

### Deferral of the scheme

On 28 May 2004, the Panel of Transport of Legislative Council held a meeting to consider the development of West and South Island Lines alongside with the highway link (Route 4).

Residential, environmental and some professional organisations support building the lines instead of highway. Rail links are more environmentally friendly and will help ease congestion of the Aberdeen Tunnel. The lines can also help sustainable development and will preserve the shoreline along western and southern Hong Kong Island.

Other transport operators and various organisations oppose the rail link, claiming that the rail link could lead to severe competition between different modes of transport, and that reduction of road transport might eventually cause job losses. Some panel members stated that the projected population growth in the south cannot support the new lines, and that the government should have a thorough plan on how to develop the Southern District before implementing the rail links.

However, some panel members suggested that the new lines could help promote tourism in the area. They asked the government to moderate the various modes of transport upon the new lines' inaugurations so as to relieve concerns from the transport operators.

Government officials stated that the low ridership of the West Rail Line and its rail incidents warranted extra planning on the new rail lines to ensure enough ridership and appropriate, cost-effective system design. Therefore, the West Island Line and South Island line project was deferred, and approval was given to the detailed planning of the highway.

## February 2005 scheme

On 25 February 2005, the Panel of Transport of Legislative Council had a meeting discussing West and South Island Line. MTR has submitted a revised scheme on 22 February and an introduction to the scheme was conducted in the meeting.

### Alignment and stations

 File:WIL-SIL-Proposal-4.png
**South Island Line (West section)**
It was separated from the West Island Line in the last proposal, running from University to Wong Chuk Hang:

* University (Interchange to West Island Line)
* Cyberport
* Wah Fu
* Aberdeen
* Wong Chuk Hang (Interchange to South Island Line (E))

**South Island Line (East section)**
It runs on the same alignment of South Island Line in Revised Scheme, and the three options stated before still exist. The line starts at South Horizons:

* South Horizons
* Lei Tung
* Wong Chuk Hang (Interchange to South Island Line (W))
* Ocean Park
* Happy Valley *(Option B, C)*
* Wan Chai *(Option B only)*
* Admiralty *(Option A, B, C)*

Detail construction methods and rail systems chosen were still unknown, but they would be the same as the Revised Alignment Scheme. The West Island Line will be a heavy rail system while the two sections of the South Island Line will use medium rail systems.

### Discussions on the new plan

The MTR claimed that the latest scheme had the following advantages:

1. No reclamation needed, and it alleviates air and noise pollution
2. Supporting tourism in Southern District: as Wong Chuk Hang will soon have nine new hotels and Ocean Park will be redeveloped

The total cost of the project, including the West Island Line, would be around HK$15 billion, and MTR was still asking the government to fund half of the construction cost.

The officials from Environmental, Transport and Works Bureau said that consideration of funding depends on the development of tourism in Southern District, especially after the submission of Ocean Park redevelopment project.

In February 2007, the government announced in a Southern District Council meeting that the South Island Line was currently at a 4th priority when it came to future railway projects, much to the anger of the district councillors present. This implied that the South Island Line was unlikely to be opened to the public before 2015.

On 10 October 2007, Chief Executive Donald Tsang announced in the policy address that the South Island Line would start construction in around 2011, and will be opened in 2015. On 27 October 2007, MTR announced that stations will be built in Wong Chuk Hang and around Ocean Park, but MTR did not confirm whether the line will pass through Wan Chai and Happy Valley.

## Executive Council scheme

On 18 December 2007, the Executive Council of Hong Kong approved the construction of the east section of South Island Line. A total of five stations will be built. The railway will be seven kilometers long, and takes 10 minutes to travel from South Horizons Station to Admiralty Station. The railway will be medium capacity system and cost HK$10 billion, which is 42% more than the original estimate of HK$7 billion back in 2006. Comparing with previous schemes, Wan Chai Station will not be built, while the construction of Happy Valley Station is under negotiation between MTR Corporation and Hong Kong Jockey Club. It has also been suggested to rename the station to "Racecourse Station"; however, that name is already used by another existing station on the East Rail Line. The construction of the west section of South Island Line has not been confirmed yet.

In March to April 2008, MTR began its public consultation works on South Island Line (East). The feaibility of building Happy Valley Station was also considered. Due to the costs and construction feasibilities, the construction of Happy Valley Station was later shelved.

In June 2011 a resident of the South Horizons private residential estate at Ap Lei Chau filed suit against the government (including the chief executive, Transport Department, and Financial Services and the Treasury Bureau) in the High Court to block the construction of the South Island Line. His suit alleged that the dust resulting from the construction of the line would cause harm to trees, and that the importation of large numbers of mainland and South Asian construction workers posed a threat to public safety.

### Construction

July 8 2011, the South Island Line (East) began construction. According to the agreement signed between MTR and the HKSAR Government, it is expected to enter service on December 2015.

December 9 2013, Ocean Park became the first station to complete flat roof works。

#### 2014

* February 19: First 3-car driverless train for South Island Line arrived at Siu Ho Wan Depot.
* March 18: Southern District Councillors visited the new train.
* May 22: Some MTR engineers pointed out that the progress of the excavation project at Admiralty Station is only halfway through, and the Nam Fung Tunnel connecting Admiralty Station to Ocean Park Station was difficult to conduct comprehensive soil exploration beforehand and thus leading to "unencountered geological problems" that has caused serious delays in the project. Although the MTR insists that it will be completed and opened to revenue service in 2015, the opening date cannot be determined. After the Democratic Party reviewed the Southern District Council documents, they found that the MTR had revised the completion date of some projects many times, but they had never informed the Southern District Council and questioned the MTR management's concealment. Due to successive delays in the works, the MTR Board of Directors has decided that serious incidents will be taken into account when paying management performance-related compensation in the future.

June 12: The MTR announced that the construction of the South Island Line (Eastern Section) was delayed. Since the target opening date of the project agreement signed earlier by the MTR and the government was set to December 2015, the expected opening date was revised to December 2016.

* June 24: Flat-top works completed for Wong Chuk Hang Depot.
* July 29: In a briefing session, MTR claimed that the entire works has been 70% completed and all works at Wong Chuk Hang Depot have been completed.
* October 17: Nam Fung Tunnel drilling works completed.

#### 2015

* April: The 10 new trains parked in Wong Chuk Hang Depot started trial runs on the tracks between Wong Chuk Hang and South Horizons Station.
* November 14: Secretary for Transport and Housing, Anthony Cheung, visited the construction site of Template:South Island Line (East).

#### 2016

* February 6: Tunnel support frame works over the Island Line tunnel near Admiralty Station has completed.
* Mid-May: MTR began to replace new flashlight maps for Island Line, Tsuen Wan Line, Kwun Tong Line and Tseung Kwan O Line trains. The new flashlight maps include partial portions of the **South Island Line** route from Admiralty to Ocean Park as well as the 2 new stations of the Template:Kwun Tong Line Extension (Ho Man Tin and Whampoa). Positions of some routes on the flashlight map are also slightly relocated to facilitate the addition of information of the 2 upcoming new lines.
* October 1: Trial operations on the entire **South Island Line** began.

#### Commencement of Service

Head of MTR Geoffrey Ma confirmed that the SIL can commence service at the end of 2016 during the opening ceremony of MTR Academy. In the press conference on November 21, MTR only announced the fare and commencement arrangements and did not announce the official commencement date. In a press conference on December 5, it was officially announced that the SIL will open to revenue service on December 28 2016.

MTR held the Opening Ceremony of the **South Island Line** on December 19 at Ocean Park Station and was presided by the HKSAR Chief Executive Leung Chun-ying. SIL stations held open days on 24 December 2016 (Christmas Eve), in which the extension part of Admiralty Station was opened from 10:00-14:00.

28 December 2016, the **South Island Line** officially opened to revenue service. CEO of MTR Lincoln Leung, Managing Director (Train Operations - Mainland China Businesses) Jacob Kam, Train Operation Director Adi Lau and other invited guests held the 'South Island Line Commencement Ceremony' at 5:20am at South Horizons Station; prior to that, the station opened 5 minutes earlier for passengers to enter the station. MTR even arranged a special 'South Island Line Commencement Special Train' (Train set: A511/A512) departing from South Horizons Station Platform 2 at 5:55am. The normal first train departed from South Horizons Station at 6:00am.
