The CBH class was ordered to haul grain trains on the open access rail network in the south of Western Australia. The trains, operated for CBH by Watco WA Rail under a long-term contract, link various CBH grain collection points in the wheatbelt with CBH terminal and port facilities in Albany, Geraldton and Kwinana. The 25 members of the CBH class are divided into three sub-classes, based on differences in power output, traction motors and rail gauge. ==Background== In early 2010, CBH Group called tenders for the first time for the transport of grain by rail. CBH's decision to go to tender was influenced by greater competition. An aim of the tender process was the development of a new and long-term arrangement for above-rail operations that would deliver a more efficient, effective grain transport and logistics service to CBH's grower members and their customers.〔 Prior to releasing the tender documents, CBH carried out extensive preliminary work to identify potential rail providers around the world, and to ensure the terms of its proposed new long term partnership would provide all parties with both the flexibility and certainty to make the necessary investment.〔 Tenders closed in June 2010 with bids lodged by rail operators from Australia and around the world including Asciano and the incumbent Australian Railroad Group. In December 2010 CBH awarded a long-term grain rail contract to Watco WA Rail. CBH also announced that it planned to invest up to $175 million in rolling stock as part of its decision to enter into the contract.〔 The 10-year agreement between CBH and Watco commenced in March 2012, and involves Watco's providing a comprehensive rail logistics planning service including train planning and scheduling, tracking, maintenance, inventory control and crew management. Watco operate and maintain the 22 locomotives and 574 wagons acquired by CBH.〔〔〔(【引用サイトリンク】url=http://www.watcocompanies.com/Railroads/WA/WA.htm )〕 In April 2011, CBH contracted MotivePower to build 22 CBH class locomotives, with the first to be delivered in March 2012. According to CBH Operations General Manager, Colin Tutt, ''"Having new equipment with more horsepower () enable () to optimise train lengths and journey times, and transport more grain to port by rail."'' Six companies from around the world lodged bids to manufacture the CBH class. CBH concluded that MotivePower's proposed locomotives would be the best option for the task of moving grain on Western Australian rail lines, as well as having good fuel economy.〔 As Australia's railways have different regulations from those of the USA, the CBH class locomotives would be of an entirely new design. MotivePower's contract with CBH for the supply of those locomotives was the first of what MotivePower hoped would be many international contracts. As compensation for late delivery of the original locomotives, CBH received a further three narrow gauge locomotives in early 2015.〔"Motive Power Roundup] ''Motive Power'' issue 98 March 2015 page 74〕〔"Rolling Stock contracts and deliveries" ''Railway Digest'' June 2015 page 42〕 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「CBH class」の詳細全文を読む スポンサード リンク
