The Eastern Line is the name of the suburban rail service in Auckland, New Zealand between Britomart and Manukau via the North Island Main Trunk (NIMT) and Manukau Branch. Services are operated by Auckland One Rail under the Auckland Transport brand. In December 2014, all Eastern Line train services began terminating at Manukau, rather than alternating between Manukau and Papakura. Electrification of the Auckland suburban network was completed in July 2015, and all passenger services on this line are electrified.
