A railroad vehicle fire-resistant floor structure with improved fire resistance against underfloor fires includes a mounting part for installing underfloor equipment on the lower surface of an underframe, and a fire-resistant member. The fire-resistant member is a fire-resistant coating applied to the lower surface of the underframe. The fire-resistant coating is preferably a foamable fire-resistant coating. A cover that covers an exposed portion exposed from the fire-resistant coating (foamable fire-resistant coating) is attached to the mounting part. The underfloor equipment is installed at the mounting part with a closing plate sandwiched therebetween.
