In order to meet different market demands, in the serial development of the Chinese standard motor train unit with 'Fuxing' number, the standard motor train unit forms a standard serial product with the speed grade of CR400/300/200, wherein the standard motor train unit with the CR200 grade gradually replaces a common passenger bus.

The power-concentrated motor train unit is used as a series of 'renaming' motor train units and plays an important role in upgrading and upgrading speed-increasing passenger cars, promoting structural reform of the railway passenger transport supply side and improving transport organization efficiency. Compared with the traditional locomotive and vehicle general speed train, the power-concentrated motor train unit adopts an operation mode without decoding, reduces the operation time of decoding, changing ends and the like, and adopts a locomotive vehicle fixed grouping and integrated maintenance mode.
