5月20日新闻――西门子将为挪威首都奥斯陆的地铁系统提供环保列车，该列车较目前在挪威首都运营的列车消耗的能源低30％。此外，该型列车报废（使用寿命约30到35年）后其约95％的材料可以回收。据一本研究杂志《Pictures of the Future》最新一期中报道，西门子开发该型列车的工程师荣获了公司环保奖。西门子公司一直致力于减少交通领域能源消耗以降低二氧化碳的排放。奥斯陆的地铁工程是其努力的一部分。西门子已经开始了运送63量列车，总计189节车厢，大约每月运送两两列车。通过在列车制动过程中将电力驱动系统转换为发生器模式产生电力，然后电力被分配到电网，这样可以减小列车耗能。
该列车长54.434米，旅客可以在自由畅通的在列车内走动，列车最高时速70公里，空车重约94吨。新型列车将最初用于4号和6号地铁，预计全部车辆运送将于2009年完成。该型列车在西门子维也纳制造厂制造，车厢外形设计由奥地利Zell am See的Porsche设计室完成。

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]
