The present invention relates to an infrared heat sensing apparatus for railcar. The purpose of the present invention is to provide an infrared heat sensing apparatus for railcar, which is capable of being installed to a predetermined part of the center of tracks to measure all areas of lower equipment with a heat detection sensor using infrared radiation if a railcar passes through the installation section to check the existence of abnormality and particularly, performing reset control of a chopper-free mode through a microcomputer, thereby improving the durability of the apparatus and increasing response speed. The infrared heat sensing apparatus for railcar according to the present invention can allow a control unit to directly generate a switching control signal without using a motor when performing a chopping function to significantly improve durability, simplify maintenance and exchange of equipment, prevent vibration and noise, and improve response speed, thereby accurately detecting heat generated by the lower equipment even if the railcar passes through the infrared heat sensing apparatus at a higher speed.
