The D-class trams are low-floor Combino trams that operate on the Melbourne tram network. They were built by Siemens in Germany, and are divided into two classes: the three section D1-class which was introduced between 2002 and 2004, and the five section D2-class which was introduced in 2004. The D-class was procured by M>Tram and have been operated by Yarra Trams since they took control of the entire tram network in April 2004. ==History== Following the privatisation of Melbourne's tram system the private operators acquired new trams to replace Z-class trams.〔(【引用サイトリンク】url=http://www.Vicsig.net/trams/class/D2 )〕 As part of this process, 59 German built Siemens, Combino low-floor trams were introduced by M>Tram at a cost of $195 million. The first tram arrived for testing in August 2002,〔(【引用サイトリンク】url=http://www.yarratrams.com.au/about-us/who-we-are/facts-figures/ )〕 and the first four entered service in late 2002.〔〔(【引用サイトリンク】url=http://www.Vicsig.net/trams/class/D1 )〕 M>Tram operations were transferred to Yarra Trams in April 2004 following negotiations with the State Government after National Express handed the M>Tram franchise back to the government in December 2002. To aid disabled access to trams from platform stops 'gap eliminators' were fitted to all 59 D-class trams in 2013. Costing $400,000 to fit to the fleet, they are a strip attached to the door step of the trams that prevent the wheels of wheelchairs from getting stuck between the door step and platform. 'Gap eliminators' proved successful in an earlier 2012 trial on two route 96 Ds, before being fitted to all D-class trams. In early 2013 all 59 D-class trams had their passenger information systems upgraded to announce upcoming stops. The upgrade, which cost $343,000, allows announcements on all routes on which D-class trams regularly travel and their alternative deviations, informing passengers of upcoming stops and connections.〔 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「D-class Melbourne tram」の詳細全文を読む スポンサード リンク
