The 'Supertram' system comprises a fleet of 25 trams built by Siemens-Duewag of Düsseldorf, Germany in 1992 for use on the Supertram light rail network in Sheffield, England. ==Supertram== After undergoing trials on Düsseldorf's Rheinbahn system, the trams were delivered to Sheffield via the Rotterdam-Immingham cargo ship route. The trams are bidirectional. Each tram comprises three articulated carriages and has a low-floor area of 40%. All four entrances are at 42 cm low level which matches the height of the platforms, thereby providing level access. The low-floor areas have limited seating and provide space for pushchairs and wheel chairs. The high floor areas are 88 cm high and can be found at the outer-end of each end carriage and in the centre carriage; they are reached by either two or three steps. Since its rail network includes gradients up to 10%, all vehicle axles are powered, which limits the low-floor area to that between the bogies. For maximized low floor area, the middle bogies are installed entirely below the centre carriage section rather than under the articulations. The wheels are type Bochum 84, have resilient rubber inserts and have a diameter of 67 cm. They may be worn to a diameter of at least 59 cm. There are four monomotor bogies, each powered by a longitudinally suspended motor driving both axles. The power supply is 750 volts DC from overhead lines using a pantograph (the Brecknell Willis High Reach pantograph). Speed is controlled from the cab by a joystick controller with a which must be continually held in place to keep the track brakes off. No other vigilance control is fitted, because of the perceived safety of a system of street-running trams. Drivers are seated on sprung seats for comfort and a PA system allows them to communicate with passengers. The vehicle interior is design to meet safety requirements. The interior fittings have no sharp edges to prevent any injury and there are numerous grab rails for standing passengers. The interior lining of the ceiling consists of aluminium honeycomb bonded with melamine coloured resin. The lining is attached to suspension points welded to the roof section. The inside walls are made from coloured melamine material. The complete lining for the articulations consists of coloured fibre-glass reinforced plastic. The rear wall of the driving cab is made of laminated wood with a melamine veneer. Passenger have 86 upholstered seats arranged face to face. The low floor areas possess minimum seating to provide space for wheelchairs in accordance with the requirements of the DPTAC. Studies were carried out by the Cranfield Institute of Technology to ensure that all members of the public may have access to the vehicles. Beginning in September 2005, the trams' manual destination boards were changed to multicolour LED signs conforming with the Disability Discrimination Act 1995 (DDA). Also, the driver-announced destination messages were replaced by recorded announcements. Three voices with local accents were chosen to record the destination messages on the three different tram lines. Following the start of a refurbishment project in January 2006, the first of the refurbished trams was launched at the Nunnery Depot on 27 January 2006. The new livery is similar to the Stagecoach bus livery, but the doors are painted orange to conform with the DDA. Since 3 February 2009, all twenty-five trams have been refurbished.〔(【引用サイトリンク】 title=Stagecoach Supertram: Refresh Update )〕 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「Siemens-Duewag Supertram」の詳細全文を読む スポンサード リンク
