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 - Westfield via Glen Innes was constructed as the Westfield deviation of the North Island Main Trunk. This deviation had been proposed as early as the 1870s, but various events meant that it was never constructed, until traffic on the Auckland - Newmarket Line began to significantly increase delays. The Westfield deviation avoided the major grades of the former main line, 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 km section was built 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 miners that were experienced from working on the construction of the North Auckland Line. The construction and opening of this line coincided with the then new Auckland Railway Station. 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. The line was completed on 24 September 1929, but did not open for traffic until 11 May 1930. In December 2014, all trains using the Eastern Line began terminating at Manukau rather than alternating between Manukau and Papakura. Similarlly, all Southern Line trains began terminating at Papakura or Pukekohe. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eastern Line, Auckland」の詳細全文を読む スポンサード リンク
