The invention discloses a three-throw turnout which is a different-direction asymmetric three-throw turnout. The three-throw turnout comprises a first trip switch, a second trip switch, a first fixed curved frog, a second fixed curved frog and a third fixed curved frog which are sequentially arranged. Forks on the side faces of the fixed curved frogs are not symmetrically distributed and are distributed in a front and back staggered mode so that the sharp corner of a switch rail can be set large and the steel rail head cross section at the same position can be wide, and therefore the strength of the switch rail can be enhanced, and service life can be prolonged. Point rails, for straight passage, of the fixed curbed frogs are straight lines, point rails, for lateral passage, of the fixed curbed frogs are curved lines, the radius of the point rails for lateral passage is the same as that of lead curve rails, in this way, equivalently the length of the lead curve rails is increased, and therefore the radius of lead curves can be increased under the condition of an existing station yard track, the lateral passage speed of a train is increased, and transportation efficiency is improved.
