The R1 was the first New York City Subway car type built for the IND. 300 cars were manufactured between 1930 and 1931 by the American Car and Foundry Company, numbered 100 through 399. Future passenger stock orders – including contracts R4, R6, R7, R7A, and R9 – were virtually identical, with minor mechanical and cosmetic variations. Therefore, these car classes are frequently referred to collectively as Arnines, or R1-9s. The R1s were also specifically sometimes referred to as City Cars. They introduced several improvements to subway car design that greatly sped up the flow of passengers in and out of trains. ==History== The first R1 cars to see passenger service were twenty individual cars to serve for two 8 car trains plus spares that were placed in revenue service on the BMT Sea Beach Line from July to November, 1931 for testing and then returned to the IND the same year.〔(【引用サイトリンク】title=Showing Image 47727 )〕 The BMT was to have been paid by the City of New York for the testing but since they were fairly extensively used in service (made up as two 8-car trains), the BMT and City called it even. In 1949 when all of the R10 cars were delivered and placed in service on the A line, approximately 224 of these R1 cars were transferred to the 36th Street Yard of the BMT Southern Division to relieve a car shortage on the BMT Lines, and used for service on the BMT # 2 (now R) Broadway 4th Avenue Local service, which was extended from Queensboro Plaza to the Astoria-Ditmars Blvd. Station of this former IRT line, which also happened in 1949 which required more cars for operating this new extended BMT service until 1961 when new R27/30's cars were delivered to the New York City Transit System's BMT Lines, which in turn replaced and released these loaned R1 cars to be sent back to the IND Division. Most R1s were retired between 1969 and 1970, as age decayed the cars' internal components, and they performed worse than their newer contemporaries. Many were replaced by the R42s, but some remained past 1970 until those cars were retired and replaced by the R44s. Following their removal from service, the majority of the fleet was scrapped. Few cars remained as work cars and were used until the 1980s. However, only one usable car originally numbered 369, was salvaged and renumbered to R4 #576 in 1969, and again renumbered to R9 #1768 in 1972, and was transferred to the East New York Yard of the Eastern Division, and was used on the former BMT J, KK, LL, M, and QJ routes until February 1977 when it was finally retired, and replaced by the R46's. Several other cars have been preserved and remain today, including: *Car #100 has been restored and is on display at the New York Transit Museum. It is the first car of the Arnine fleet, numerically. *Car #103 has been preserved by Railway Preservation Corp. and is currently undergoing restoration at 207th Street Yard. *Car #381 has been preserved by Railway Preservation Corp. and has been restored. It is currently stored at 207th Street Yard. Car 175 is at the Seashore Trolley Museum, but is used only for storage. It does not have trucks, and two of its side doors were donated to R4 #401 which has been preserved by Railway Preservation Corp. and restored. 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「R1 (New York City Subway car)」の詳細全文を読む スポンサード リンク
