The invention provides a switch structure for a rubber crossing and a rail system, and relates to the technical field of railways. The structure comprises a basic track and a pointed track; the basictrack comprises a straight basic track and a curved basic track; the straight basic track and the curved basic track are oppositely arranged; the pointed track includes a curved pointed track and a linear pointed track; the curved pointed track and the linear pointed track are disposed between the straight basic track and the curved basic track, the curved pointed track is adjacent to the straightbasic track, and the linear pointed track is adjacent to the curved basic track; a curved angle steel vertical wall is disposed inside the curved pointed track; a straight angle steel vertical wall is disposed on an inner side of the linear pointed track; a rubber crossing plate is laid between the curved angle steel vertical wall and the straight angle steel vertical wall, and is fixed through the curved angle steel vertical wall and the straight angle steel vertical wall.
