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 and Manukau Branch. Services are operated by Transdev under the AT brand.

Construction

The line from Auckland to Westfield via Glen Innes was constructed as the Westfield Deviation of the North Island Main Trunk. This eastern deviation had been proposed as early as the 1870s, but various events meant that it was never constructed, until traffic on the Auckland – Newmarket section of the NIMT began to experience significant delays. The Westfield Deviation avoided the major grades of the route via Newmarket, which had a highest point of 81m above sea level, compared with the new line's highest point of 24m.

A small reclamation had been made in the early 1920s 2 km out of Queen Street into Mechanics Bay for goods yards and maintenance sheds. The remaining 14.28 km (8 miles & 70 chain) section was built as the Westfield Deviation between 1924 and 1930 by the Public Works Department as part of general improvements to Auckland's rail network. The Purewa Tunnel, a major engineering work halfway between the city and Glen Innes, was built in the mid-1920s by experienced miners who had worked on the construction of the North Auckland Line.[1]

The section from Mechanics Bay to Orakei required significant reclamation over Hobson Bay. At the same time a new road, Tamaki Drive, was built alongside part of the railway line. A notable feature of the deviation is that no road-rail level crossings were created by its construction.[2]

The Westfield Deviation via the Purewa Tunnel opened for goods traffic on 1 September 1929 using the down line to Westfield for single-line working, but was not used for passenger traffic until the up line to Auckland was opened on 11 May 1930.[3][4] The construction and opening of this line coincided with the then new Auckland Railway Station.

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 suburban services on this line are electric.
