North Island Line ‘Swap Scheme’
This map shows what the MTR would have looked like in the near future if the government had selected the ‘Swap Scheme’ for the proposed North Island Line (along with other completed proposals like the Sha Tin to Central Link). This plan would have involved the western and central sections of the Island Line merging with the Tseung Kwan O Line and the eastern portion of the line joining an extended Tung Chung Line. Although this proposal would be more effective at relieving congestion on the Island Line, the ‘Interchange’ option – which leaves the Island Line as is – has been selected instead due to costs and a desire to not to mess with existing commuter patterns.
