The present invention provides a movable point frog. In this application, quasi-continuity of rails is achieved at the frog, so that a gap in the frog is eliminated, vibration and noise are reduced, and transverse impact of wheels is eliminated. Guard rails do not need to be disposed. The frog itself does not limit the speed of a train running on a main line and a branch line. Therefore, the train running on the main line can pass through the frog without reducing the speed. A relatively small curve radius and a relatively large frog angle may be adopted for the branch line. Compared with integrally cast frog equipment in the prior art, all the components in this application are detachably connected, and therefore can be simply mounted, easily maintained, and produced in batch.
