5月20日新聞――西門(mén)子將為挪威首都奧斯陸的地鐵系統(tǒng)提供環(huán)保列車(chē)，該列車(chē)較目前在挪威首都運(yùn)營(yíng)的列車(chē)消耗的能源低30％。此外，該型列車(chē)報(bào)廢（使用壽命約30到35年）后其約95％的材料可以回收。據(jù)一本研究雜志《Pictures of the Future》最新一期中報(bào)道，西門(mén)子開(kāi)發(fā)該型列車(chē)的工程師榮獲了公司環(huán)保獎(jiǎng)。西門(mén)子公司一直致力于減少交通領(lǐng)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(mén)子已經(jīng)開(kāi)始了運(yùn)送63量列車(chē)，總計(jì)189節(jié)車(chē)廂，大約每月運(yùn)送兩兩列車(chē)。通過(guò)在列車(chē)制動(dòng)過(guò)程中將電力驅(qū)動(dòng)系統(tǒng)轉(zhuǎn)換為發(fā)生器模式產(chǎn)生電力，然后電力被分配到電網(wǎng)，這樣可以減小列車(chē)耗能。 車(chē)廂完全是鋁制，這是一種輕型材料，列車(chē)越輕，加速消耗的能量越小，經(jīng)營(yíng)奧斯陸地鐵系統(tǒng)的Oslo Sporveier公司通過(guò)使用新型列車(chē)可以節(jié)約33％經(jīng)營(yíng)成本。由于奧斯陸冬天氣候非常寒冷，西門(mén)子工程師還設(shè)計(jì)該型列車(chē)可以承受-25℃的運(yùn)行溫度。 在選擇列車(chē)用材料時(shí)，西門(mén)子交通系統(tǒng)的工程師集中關(guān)注環(huán)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(chē)模塊化的設(shè)計(jì)還意味著其部件可以簡(jiǎn)單替換維修，這也降低了維修成本。地鐵列車(chē)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(jìn)的材料價(jià)格，出售一輛列車(chē)的材料可以掙得約60，000歐元。 該列車(chē)長(zhǎng)54.434米，旅客可以在自由暢通的在列車(chē)內(nèi)走動(dòng)，列車(chē)最高時(shí)速70公里，空車(chē)重約94噸。新型列車(chē)將最初用于4號(hào)和6號(hào)地鐵，預(yù)計(jì)全部車(chē)輛運(yùn)送將于2009年完成。該型列車(chē)在西門(mén)子維也納制造廠制造，車(chē)廂外形設(shè)計(jì)由奧地利Zell am See的Porsche設(shè)計(jì)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]
