PURPOSE: A T shape crosstie is provided to improve drainage of railroads, to prevent disorder of tracks and to improve lateral resisting force and longitudinal resisting force. CONSTITUTION: A T shape crosstie comprises a linear type main supporting board(200), a protrusion part(300), a shoulder(400), and a reinforcement part(500). The main supporting board is connected to the width direction of railroads and includes a rail supporting part(200R) which a rail(100) is fixed in the upper side. The protrusion part is installed in the central part of the side of the main supporting board. The shoulder is installed at both sides of the rail supporting part in order to fix the rail. The reinforcement part connects to the main supporting board and the protrusion part and includes an exposed surface(510) which is exposed to the outside.
