5月20日新聞――西門子將為挪威首都奧斯陸的地鐵系統提供環保列車，該列車較目前在挪威首都運營的列車消耗的能源低30％。此外，該型列車報廢（使用壽命約30到35年）后其約95％的材料可以回收。據一本研究雜志《Pictures of the Future》最新一期中報道，西門子開發該型列車的工程師榮獲了公司環保獎。西門子公司一直致力于減少交通領域能源消耗以降低二氧化碳的排放。奧斯陸的地鐵工程是其努力的一部分。西門子已經開始了運送63量列車，總計189節車廂，大約每月運送兩兩列車。通過在列車制動過程中將電力驅動系統轉換為發生器模式產生電力，然后電力被分配到電網，這樣可以減小列車耗能。 車廂完全是鋁制，這是一種輕型材料，列車越輕，加速消耗的能量越小，經營奧斯陸地鐵系統的Oslo Sporveier公司通過使用新型列車可以節約33％經營成本。由于奧斯陸冬天氣候非常寒冷，西門子工程師還設計該型列車可以承受-25℃的運行溫度。 在選擇列車用材料時，西門子交通系統的工程師集中關注環保因素。他們避免使用污染材料，并盡可能降低元器件重量。列車模塊化的設計還意味著其部件可以簡單替換維修，這也降低了維修成本。地鐵列車的配置理念使得85％的材料可以物理上重新使用，另有10％可以加熱回收，以先進的材料價格，出售一輛列車的材料可以掙得約60，000歐元。 該列車長54.434米，旅客可以在自由暢通的在列車內走動，列車最高時速70公里，空車重約94噸。新型列車將最初用于4號和6號地鐵，預計全部車輛運送將于2009年完成。該型列車在西門子維也納制造廠制造，車廂外形設計由奧地利Zell am See的Porsche設計室完成。 original text： [COLOR=#708090]Eco-friendly Subway from Siemens in Oslo 20.05.07 ｜ Siemens is supplying Oslo‘s subway system with environmentally friendly trains that consume 30 percent less energy than those currently in operation in the Norwegian capital. What‘s more, about 95 percent of the materials used in the trains can be recycled after their service life, an estimated 30 to 35 years, comes to an end. As the research magazine "Pictures of the Future" reports in its latest issue, the Siemens engineers who developed the trains received the company‘s Environmental Award. The Oslo subway project is part of Siemens‘ ongoing effort to reduce energy consumption in the transport sector in order to lower carbon dioxide emissions. Delivery of the 63 trains, which comprise a total of 189 cars, is already under way, with about two new trains arriving in Oslo monthly. The rail vehicles‘ impressive energy savings is achieved by having the electric drive systems switch to a generator mode during braking, with the electricity thus created then channeled back into the grid. The rail car bodies are also made entirely of aluminum, which is a lightweight material — and the lighter a train is, the less energy it takes to accelerate it. AS Oslo Sporveier, which operates the subway system, will end up saving 33 percent in operating costs with the new trains. Due to the extremely cold winters in Oslo, Siemens engineers also designed the trains to withstand operating temperatures as low as minus 25 degrees Celsius. Engineers at Siemens Transportation Systems focused on environmental aspects when selecting all the materials used for the trains. Their efforts included avoiding the use of pollutant materials and reducing the weight of components as much as possible. The trains‘ modular design also means that parts can be replaced and repaired easily, which also lowers maintenance costs. The disposal concept for the subway trains provides for 85 percent of the materials to be physically re-used, and a further ten percent to be thermally recycled. At today‘s prices, selling the material of one train would earn around €60,000. The trains are 54.34 meters long, and passengers can move unobstructed through their entire length. They have a top speed of 70 kilometers per hour and weigh approximately 94 tons when empty. The new trains will initially be used on Metro lines 4 and 6, and deliveries are scheduled to be completed in the summer of 2009. Siemens is building the trains at its plant in Vienna. The rail car exteriors were designed by Porsche Design Studio in Zell am See, Austria.[/COLOR]
