China has been making great strides in mass transit in the past year. They're building a huge Asia-Europe rail network, rapidly expanding their national high speed rail lines and have unveiled the world's fastest high-speed train. The country has now revealed a fuel cell light rail locomotive for local, city-wide and suburban transportation.
The locomotive was developed by the China North Vehicle Yongji Electric Motor Corporation and the Southwest Jiaotong University. The train is powered by a permanent-magnet motor and hydrogen fuel cells that run a synchronous motor and frequency converter. This set up allows the train to produce and use power very efficiently while also cutting down on vibrations and noise.
The magnet motor out-performs traditional motors while reducing energy use by 10 - 20 percent.via Inhabitat
