Mentougou Line (Chinese: 门头沟线; pinyin: Méntóugōu Xiàn) formerly known as Datai Line (Chinese: 大台线; pinyin: Dàtái Xiàn), or Beijing Maglev Trains (Chinese: 北京低速磁悬浮; pinyin: Běijīng Dīsù Cíxuánfú) is a magnetic levitation train currently under construction. It will be operated by the Beijing Mass Transit Railway Operation Co., Ltd. Mentougou Line will start from the Dinghuiqiao North Number Five Road on the West Fourth Ring Road, and will go west towards Mentougou.[dead link][1] The subway line is scheduled to be operational sometime in 2017.[2] Once completed, it will be China's 3rd commercial maglev train in operation.[3]

Trains will use the low and medium speed magnetic levitation technology which can give a top speed of 105 kilometers per hour.[4][5]

A report in February 2013 said all preparatory work was complete and construction would commence "once the National Development and Reform Commission (NDRC) grants its approval."[6]

The line is part of Beijing's attempts to tackle environmental problems caused by heavy car use, coal burning and fast urbanisation. Another reason is that many cities are reportedly upgrading their urban rail systems and introducing green technologies - unlike diesel or coal electric trains do not produce direct emissions.[3]

Six coach maglev trains will be built by the China CNR (by subsidiary Tangshan Railway Vehicle), making it the first domestically built Chinese maglev train. [3]

Trials of the new line commenced in August 2017 with opening projected by the end of the year.[7]
