The invention discloses a formwork transfer method for railway simply supported beam slip form construction. The formwork transfer method comprises the following steps that S1, a slip form track is measured and positioned; the position of the slip form track is accurately positioned and fixed at the position, corresponding to a box girder flange plate, of a next-span box girder support according to surveying and setting-out; s2, the box girder formwork assembly and the girder body are separated for formwork descending; s3, transferring is completed by means of a trolley; the trolley comprises a supporting platform and pulleys located at the four corners of the bottom of the supporting platform, and the winch drags the trolley to move to the position of a next-span box girder formwork along the sliding formwork rail. S4, the box girder formwork assembly is jacked for formwork lifting; after the trolley and the box girder formwork assembly reach the designated position of the next span of the box girder, a cork
