The C sets are a class of electric multiple unit train operated by Sydney Trains in New South Wales, Australia. The carriages are of stainless steel, double deck construction. ==Design & construction== The C sets were a follow-on from the K sets. They were built as an interim measure due to the lateness of the Tangara program. They were the first Sydney suburban trains to be fitted with chopper control, which gives the train smoother acceleration. Gate turn-off thyristors were used to control power to the traction motors, hence allowing for smoother acceleration.〔"New Suburban Train" ''Railway Digest'' September 1986 Page 273 〕 Following the success of the implementation of chopper control, these features were later installed on the Tangara and later V set carriages. The C set carriages were also the first on the suburban network to feature fixed seating (originally covered with fabric, since replaced with vinyl).〔 This proved to be unpopular, but nevertheless, fixed seating was later used on the suburban Tangara cars. These cars also featured push-button doors requiring passengers to activate, to increase air-conditioning efficiency. These proved unpopular and the push-buttons on the doors were removed. The C set is distinguished externally by a fibreglass molding mounted on the front of the power carriage. It was originally in the State Rail Authority white with orange and red candy livery stripes on the lower portion. C3596 was the only power car to have its Candy-liveried front repainted in CityRail blue and yellow prior to its Citydecker refurbishment in 1998. The chopper cars are amongst the heaviest in the suburban fleet, with the power cars weighing 52 tonnes. The order was for 56 cars: :Power cars - C3581-C3608 :Trailer cars - T4247-T4274 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「Sydney Trains C set」の詳細全文を読む スポンサード リンク
