The New Zealand DL class of diesel-electric locomotives was manufactured for KiwiRail by Dalian Locomotive and Rolling Stock Company with engines from MTU. They are the most powerful diesel-electric locomotives in service in New Zealand. Twenty locomotives were ordered in 2009 and delivered in 2010-2011, a further 20 in 2011 for 2012 delivery, postponed to 2013 due to reliability problems.〔 Another batch of eight were ordered in September 2013.〔(【引用サイトリンク】title=KiwiRail places third order for CNR Dalian locomotives )〕 The third batch arrived in 2015. They were the first new-build diesel-electric mainline locomotives on the New Zealand railway network in 30 years,〔with the last being the DF class, which entered service in 1979–1981〕 The order marked one of the first steps of considerable investment in KiwiRail, and the first order for a Chinese-built locomotive from a western country. == Background == The acquisition of new locomotives was first proposed by Toll NZ after they purchased Tranz Rail in 2003.〔(【引用サイトリンク】title=Billion-dollar buyback )〕 When Toll assumed responsibility for the rail operation, the New Zealand Railways Corporation again took over the maintenance of the railway network under the trading name ONTRACK. After several years of negotiations the two parties could not come to an agreement on the amount that Toll should pay for access to the rail network (track access fees), and Toll did not purchase any new locomotives while this issue remained unsolved. In July 2008, the fifth Labour Government purchased Toll Rail from Toll, renamed it KiwiRail, and merged it with ONTRACK, creating one company that controls both operations and rail infrastructure. Soon after the new company was officially launched, the State Owned Enterprises Minister Trevor Mallard announced that the government was investigating the possibility of assembling new locomotives at Hutt Workshops, then operated by United Group Rail, from imported parts. Following the election of the fifth National government in November 2008, the investment programme initiated by the previous administration was suspended pending a review. In March 2009, the government announced that it had authorised KiwiRail to invest $115m in new rolling stock: $75m for 20 locomotives, and $40m for new carriages for Tranz Scenic, (now KiwiRail Scenic Journeys).〔 The locomotives were to be built in China by Dalian Locomotive and Rolling Stock (CNR Group). 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「New Zealand DL class locomotive」の詳細全文を読む スポンサード リンク
