The rolling stock of the Washington Metro system consists of 1,130 cars, delivered in seven shipments. All rail cars in the Metrorail system operate in married pairs (consecutively numbered even-odd), with systems shared across the pair. The system rail gauge is a modified, or near, standard gauge , closer than standard gauge. The platform height is said to be above top of rail (ATR) and rolling stock floor height is also 38 ± in (978 ± 19 mm) ATR for level entry. The Washington Metro’s floors and platforms are lower than those of most other East Coast mass transit systems, such as in New York City, Boston, and Philadelphia. The number of revenue cars remained constant until April 14, 2015, when the first of the 7000 series cars started passenger service. == 1000-series == The original order of 300 Metro cars was manufactured by Rohr Industries, with delivery in 1976. These cars are numbered 1000–1299, and were rehabilitated in the mid-1990s by Breda Costruzioni Ferroviarie (now AnsaldoBreda) and WMATA at their Brentwood Shop in northeast Washington, D.C. There are two major characteristics that distinguish the 1000-series from the later series cars. On their sides, the cars had two mylar curtain rollsigns, one above a window next to the doors on each end, while the other car classes have a single flip-dot or LED sign above a window next to the center doors. Second, the bulkheads on each end of the 1000-series cars feature windows that extend to the top of the bulkhead frame, whereas other car classes' bulkhead windows only extend slightly higher than the side windows. The 1993 rehabilitation converted one rollsign on each side into an exterior loudspeaker while the other rollsign, as well as the bulkhead signs, were converted to flip-dot displays, replacing the original rollsigns. The cars also received AC propulsion, replacing the cam-controlled DC propulsion systems, making them the first cars on the system to use such propulsion. The original interiors have a white grained appearance with 82 orange and brown seats. Future orders would have seating reduced down to 64 or 68, as seats next to the doors would be removed for additional standing areas. , Metrorail was testing new overhead handles of different styles on 1122, 1123, 1126, 1127, as well as some 3000-series cars to gauge public opinion. Following the June 22, 2009 collision, Metro implemented a policy of no longer placing 1000-Series rail car pairs at the ends of train consists in order to prevent telescoping in a collision, as they are the weakest rolling stock structurally. The new policy places 1000-Series cars in the center of six and eight-car consists, with rail cars of other series in the end positions. These cars, and the 4000 series, are being retired by the 7000 series since 2015. In July 2015, Metro released a request for proposals seeking a contractor to pick-up and dispose of Metro's entire remaining fleet of 1000-series railcars.〔http://www.wmata.com/business/procurement_and_contracting/solicitations/uploads/RFP%20NO.%20CQ15217%20Pick-Up%20and%20Disposal%20Services%20for%201000%20&%204000%20Series%20Railcars1.pdf〕 Of the 300 cars, less than 290 remain in active revenue service. Car 1028, separated from its mate after it was destroyed during the Federal Triangle derailment in 1982, has become the feeler car that checks system clearances. Cars 1114–1115 are used only in work service. Four cars, formerly numbered 1010-1011 and 1044-1045, were renumbered to 8000–8003 and serve the money train to collect the revenue from station fare card machines. 1076 is also permanently out of service after its mate was destroyed in the 2004 accident at Woodley Park station. 1079 was the lead car on the second train involved in the June 22, 2009 Washington Metro train collision. Recently, cars 1090-1091 were spotted at the Asymmetric Warfare Training Center at Fort AP Hill.〔https://www.dvidshub.net/video/320460/awtc-opens-enhance-awgs-capabilities#.Vfrxl5c2Hgk〕 Eight cars were taken to the Guardian Centers facility in Georgia.〔http://guardiancenters.com/portfolio/dual-rail-mass-transit-subway-system/〕 * ''Car Builder'': Rohr Industries, Winder, Georgia, USA * ''Dates Built'': 1973–1976 * ''Rehabilitated'': 1993–1996 * ''Rehabilitated by'': WMATA Brentwood Shop/Breda Costruzioni Ferroviarie (now AnsaldoBreda), Washington, DC, USA * ''Car Body'': Extruded Aluminum * ''Car Numbers'': 1000–1299 * ''Car Length'': * ''Car Width'': * ''Car Height'': * ''Track Gauge'': * ''Truck Type'': Cast Steel * ''Maximum Operating Speed'': * ''Propulsion System'': Four General Electric "5GEB" 3 Phase, 4 pole, Asynchronous AC Traction Drives with GTO Inverters (post rehab) * ''Power Output (Per Motor)'': 〔 * ''Power Output (Per Car)'': * ''Braking System'': Abex Hydraulics * ''Seating capacity'': 82 * ''Total Capacity'': 175 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「Washington Metro rolling stock」の詳細全文を読む スポンサード リンク
