The K sets are an Australian class of electric multiple unit operated by Sydney Trains in New South Wales. The carriages are of stainless steel, double deck construction. ==Design & construction== The K sets were the first New South Wales suburban trains to be air conditioned and have headlights. Two orders were placed for the K sets with all manufactured in 1981–85 by A Goninan & Co, Broadmeadow: *Order 1 :50 Power cars: C3501-C3550 :4 Driving trailer cars: D4096-D4099, converted to standard trailer cars in 2014 :46 Trailer cars: T4171-T4216 *Order 2 :30 Power cars: C3551-C3580 :30 Trailer cars: T4217-T4246 The first order featured low mounted upper deck windows, cream and brown interiors, and unpainted fronts. The second order featured higher mounted upper deck windows, yellow and mustard interiors and State Rail Authority candy livery fronts.〔"D22.98 Interior Colour Scheme for Surburban Trains" ''Railway Digest'' May 1984 page 172〕 The first four trailers were built as driving trailers allowing them to operate in two-car formation, although in practice they were formed into four carriage sets and often ran together as one eight-car set until 1988.〔"EMU Review" ''Railway Digest'' March 1989 Page 85〕 These also differed in the subsequent deliveries in being fitted with air conditioning from new, rather than pressure ventilation. To provide a spare, C3550 & T4216 were also built with air conditioning. All ten carriages were fitted with different windows, being sheet glass with small opening hoppers. This was replaced with sheet glass in 1993.〔"Other Double Deck Suburbans" ''Railway Digest'' August 1993 page 343〕 To accommodate the air conditioning and associated equipment, the pantograph had to be shifted to the adjacent trailer car to which the power car is semi-permanently coupled with high voltage cables connecting the two cars. Although some power cars and trailers have been broken up and married with others during periods of heavy maintenance, many original combinations remain. 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 K set」の詳細全文を読む スポンサード リンク
