PURPOSE: A prefabricated crossing of a railroad turnout is provided to enable the easy replacement of a nose unit and a nose rail when the nose unit and the nose rail are worn away. CONSTITUTION: A prefabricated crossing of a railroad turnout comprises wing rails(10), nose rails(20), and a nose unit forming body(30). A nose unit forming unit is formed on the front of the nose unit forming body, and a V-shaped groove is formed on the rear thereof. The nose unit forming body has excellent abrasion-resistance and is coupled to the nose rails. The wing rails, the nose rails, and the nose unit forming body are connected to each other through pins or bolts(41).
