The R16 was a New York City Subway car manufactured by American Car and Foundry Company from 1954 to 1955 in a kale green paint scheme. The R16s were numbered 6300–6499, and were retired in the late 1970s up through 1983. ==History== First placed into passenger service on January 10, 1955 on the BMT #15, (now ). 50 of the R16 cars (6300-6349) were transferred to the line in preparation for the opening of the former Long Island Rail Road's IND Rockaway Line on June 28, 1956. The Transit Authority wished to use its newest equipment available for the line's inaugural.〔As shown in these pictures: * *〕 After the late 1950s, the 50 R16s were returned to the BMT Eastern Division and would remain there until the late 1960s and the early 1970s when they were transferred to various lines throughout the system. During the 1970s, R16's could be found intermixed with other cars and in far away places from their previous running grounds. Photos of R16's in the Bronx or Queens show them both in complete consists as well as with strange bedfellows. When delivered, the R16's quickly became the new standard in car design for the New York City Transit Authority. Structurally and mechanically, they were the larger versions of the R17s and yet basically an improved version of the R10s with same exact dimensions except that the R16's had electrically operated door motors while the R10s had pneumatic door engines. When they were new, the R16's could give the R10 some competition when it came to speed - both cars were mechanically similar with four 100 horsepower motors and a balancing speed of 55 MPH. The R16, like the older Arnines, R10s, and R11s, featured three sets of mid-carbody passenger windows on each side. One set contained an illuminated rollsign box in lieu of a second window. This sign box had three readings arranged vertically - the top two being the train's terminals, and the bottom being the route. This window and signbox pattern became standard for later cars until the R40s. The R16 would also be the last car class delivered with cross wise seating until the R44 order in 1972. Two cars were painted gold for a celebration in 1955, and most were painted bright red in 1968. The whole fleet was given the new MTA corporate silver and blue scheme in 1970, keeping that paint until the cars were retired, some for as long as 17 years. There were two versions of R16: Westinghouse (R16WH) equipped cars 6300-6399 and the earlier delivered General Electric (R16GE) equipped cars 6400-6499. The General Electric propulsion gear used forced air to cool the rheostatic resistors used for acceleration and dynamic braking. The low voltage rotary converter (motor-generator) was used to provide the air and proved to be problematic as the enclosure tended to trap dirt and rain water within, leading to high failure rates. The Westinghouse cars had resistors mounted in the open for slip stream cooling as had been the traditional means, and the method used subsequent to the R22 order. In theory, both could be run together however in practice this was found to be less than desirable. Later in their service lives, cars of all classes would be segregated by electrical running gear, helping to provide better fleet reliability. During the early 1970s, the R16's had their door motors replaced with ones similar to the R44's. As the replacement door motors were mounted in the walls rather than in the original locations under the seats;〔(【引用サイトリンク】title=www.nycsubway.org )〕 this resulted in distinctive sloping wall panels unique to the car class.〔(Before ) and (After )〕 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「R16 (New York City Subway car)」の詳細全文を読む スポンサード リンク
