PURPOSE: A crossing of a railway turnout is provided to decrease an impact caused by a joint and to be worn away evenly by letting wheels of a train pass through an arched part and a joint of nose blocks and the upper side of a short nose rail simultaneously. CONSTITUTION: The crossing(1) of a railway turnout using nose blocks(10) comprises the steps of installing wing rails(2) using general rails, installing nose blocks(10) between the wing rails(2), and connecting nose rails(20) to the rear ends of the nose blocks(10) using bolts(32) and spacers(30).
