The invention provides a method for refitting a double-layer passenger train sliding plug door into a wide folding door, and relates to the technical field of double-layer passenger train door manufacturing. The method includes the following steps that firstly, the size of a side wall steel structure of the existing train sliding plug door is changed; secondly, a new steel structure integrated door frame is designed and installed; and thirdly, the wide folding door is designed. By means of the method, the train structure is analyzed, factors such as limitation of the existing train structure and passenger passing requirements are comprehensively considered, and the existing double-leaf sliding plug door which can not be maintained is refitted and designed into the wide folding door; the boundary dimension of the folding door is redesigned; and check computation is conducted on the positions of a door inner plate and a framework, and it is ensured that the overall door plate structure meets the quality requirement. By means of the method, the operation requirement for achieving the large passenger flow passing volume within the short parking time is met, and cost is reduced for later maintenance of a train.
