UMT has entered a rapid development period in China, characterised by a parallel development of different urban transit forms, there is a new tendency of diversified UMT development. The author holds that the suburban railway is a good solution to the problems like overcrowding of residents, poor living condition and the construction of new towns. The suburban railway also makes it possible to save investment and is therefore significant in strategic guidance. Facing this new tendency, the author argues that reasonable measures shall be taken for the planning of UMT, including the selection of the operation speed, the train body, which shall be the unitization design on the principle of safety, reliability, economy, practical use and advanced techniques.
