The Stadler GTW is an articulated railcar for local transport made by Stadler Rail of Switzerland. GTW stands for Gelenktriebwagen (articulated railcar). ==History== The Biel-Täuffelen-Ins-Bahn near Bern, Switzerland was looking for a lighter train model to replace its aging fleet, so that a low floor system does not require heavy installations on the roof. Based on that requirement Stadler came up with a concept of placing most of the equipment in a central unit between the seating cars. While the BTI-Bahn tracks are meter gauge, Stadler presented the first prototype in 1995 set on standard gauge rails, and the Mittelthurgau-Bahn was testing three prototypes on its standard gauge network during 1996. The rolling stock for Mittelthurgau was later expanded to 10 GTW 2/6 (built 1998-1999) that are now part of the THURBO fleet (the three prototypes were sold to Italy). The next lots were produced in meter gauge being delivered to the BTI-Bahn and the CEV-Bahn (Chemins de fer électriques Veveysans) in 1997. During that time the Hessische Landesbahn in Germany was also looking at the new system but actual procurement was delayed until the second generation. In the beginning, Stadler was cooperating with ADtranz/DWA with the initial batch produced in 1999 at DWA Bautzen (Brandenburg). Its headshape design follows the style of the Deutsche Bahn trains as they were already on production at DWA, and eventually Deutsche Bahn did also order a batch. The full series were then manufactured at the new Stadler Pankow (Berlin) facilities being built in 2000 by a joint venture with ADtranz. Stadler acquired their shares in 2001 and the final vehicles were delivered in 2001 by Stadler alone. The second generation can be easily distinguished by its round headshape made from GFK (glass-fiber reinforced plastic). These follow the DB design being produced since 2000 in the Swiss facilities as well. By the time the available options had already expanded - meter gauge vehicles can be ordered in a 2.2 or 2.7 m width and the standard gauge vehicles in a 3.0 or 3.1 m width. The GTW 2/6 may be expanded with an additional bogie car making it a GTW 2/8. The third generation has minor modifications to the headshape but the more important changes were made to the power module - the electric variant has now 700-800 kW (instead of up to 520 kW) and the diesel-electric variant is available as a DMU-2 with two generators instead of one. This allowed to increase the maximum speed as it was required by the Italian customers where they are named ATR 100 (built since 2004). The fourth generation came along with new regulations in the EU that were increasing the crash worthiness requirements (see DIN EN 15227). These must be fulfilled by atleast 2008 (see 2008/57/EC). This is the same year that much of the production was moved to the branch factory in Siedlce, Poland. 551 units have been sold until 2011〔http://www.stadlerrail.com/medien/2011/04/08/stadler-zuge-fur-apulien/〕 and are in use in Austria, France, Germany, Italy, the Netherlands, Slovakia, Switzerland and the United States. 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「Stadler GTW」の詳細全文を読む スポンサード リンク
