North Island Line is a proposed reformation of the existing Island Line and extension of Tung Chung Line of the Hong Kong MTR metro system. According to the documentary, Rail Projects Under Planning 2000, released by Highways Department, the current Tung Chung Line will be extended from Hong Kong terminus eastward and two new stations, Tamar Station and Exhibition Station are proposed on the extension. The new route will then join and substitute the Island Line from Fortress Hill Station to Chai Wan terminus. Tseung Kwan O Line will have new constructed tunnel connected from its North Point terminus to Tin Hau Station without passing Fortress Hill Station and substitute the remaining western half of Island Line. The difficulties of constructing North Island Line include updating the signalling apparatus of Island Line to be compatible with the apparatus which has been installed in Tung Chung Line.
The extension of Tung Chung Line forms part of the third phase of land reclamation of Victoria Harbour on Hong Kong Island's northern coast. Due to the disagreement from public and political parties such as Society for Protection of the Harbour and the insufficient traffic demand, the MTR Corporation has never given the proposal a commencement date. To add more uncertainty, the proposed Shatin to Central Link and the merger of MTRC and KCRC also influence the fate of North Island Line. Due to said reasons, in 2003 Hong Kong Government have postponed it indefinitely. However, the MTRC included the Sha Tin to Central Link and the North Island Line details in the diagrams of the latest schemes of the West Island Line and South Island Line, released in 2008. Those diagrams have excluded the now cancelled Central South Station and Racecourse Station.
On 21 February 2013, the Highways Department launched stage 2 public engagement consultation of Our Future Railway, and proposed two schemes of North Island Line. In addition to a "Swap" scheme which was similar to previous proposals, the consultation documents also included a second "Interchange" scheme.
The existing Tung Chung Line will be extended along the northern coast of Hong Kong Island, with Tamar, Exhibition and Causeway Bay North Stations along the path. The extension will then connects eastwards to the existing Island Line Fortress Hill Station, and take up the remaining Island Line section to Chai Wan Station.
At the same time, Tseung Kwan O Line will extend from its current westbound terminus North Point Station to the existing Island Line Tin Hau Station, and take up the remaining Island Line to Kennedy Town Station.
This scheme greatly increases the number of stations reached by Tung Chung Line and Tseung Kwan O Line on the Hong Kong Island, but east-west directional traffic along the existing Island Line will be interrupted and require an interchange. Also, the maximum train frequency between Fortress Hill and Chai Wan Stations, which are taken up by Tung Chung Line, will have to reduce by 8 trains per hour.
Both the existing Tung Chung Line and Tseung Kwan O Line will be extended along the northern coast of Hong Kong Island. Three stations, namely Tamar, Exhibition and Causeway Bay North, will be constructed along the extensions, and either Tamar or Causeway Bay North Station will be chosen as an interchange between the two lines.
This scheme preserves the existing Island Line and does not change the current communication pattern between Central and Western District and Eastern District. However, as Tung Chung and Tseung Kwan O Lines will not be connected to Island Line, some passengers would still need to make an interchange like they currently do. Also, this arrangement will do less than the "Swap" scheme to relieve congestion, since although the number of stations and the area served has increased, the link with the current Island Line is still the same, unlike the "Swap" scheme.
