The 100 Series are a number of underground cars manufactured by Alstom in Brazil and Argentina for use on the Buenos Aires Underground. They are used exclusively on Line D of the network, where they make up the vast majority of the fleet, serving alongside Fiat-Materfer cars. ==History== The 100 Series was initially purchased for use on Line A to replace the ageing La Brugeoise cars, however they ended up replacing the slightly newer Siemens-Schuckert Orenstein & Koppel cars which served on Line D instead. Originally, the purchase consisted of 80 cars for a total of 16 trains made up of 5 cars each, due to the shorter platform length on Line A. However, 16 more 100 Series cars continued to be purchased in that decade up until 2009, making a total of 96 cars and allowing each train to have 6 cars, making full use of the line's platforms.〔(Finalizó la entrega de los Alstom Metrópolis ) - EnElSubte, 9 March 2009.〕 In 2015 the cars began to receive a mid-life refurbishment, primarily to add air conditioning, but also incorporating more minor aesthetic differences to the interior such as improved lighting and new upholstery. Despite enjoying a successful service life, they are also the noisiest cars on the network. New Alstom cars, but of a different model, are set to replace the Fiat-Materfer cars and serve alongside the existing 100 Series cars in 2017-2019. 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「Buenos Aires Underground 100 Series」の詳細全文を読む スポンサード リンク
