Based on the map in the 2011 MTR Annual Report, the Northern Link is designed with two termini to the north, similar to the Tseung Kwan O line. These termini are expected to be at the existing Lok Ma Chau station and the proposed Kwu Tung station. Chau Tau Station was not depicted on the map, suggesting that it may not be constructed. However, there remains a possibility for Chau Tau Station to be built as an intermediate station on the Lok Ma Chau branch of both lines.
