A tank car comprises running gears, automatic coupling, draw-buffing and braking equipment, a boiler connected to a frame, with cross-section area in the middle part more than in the console parts. The boiler is made of at least five shells, which are bodies of rotation, and two bottoms. The middle shell is made in the form of two half-cylinders, connected by flat inserts. The console shells are cylindrical, and the intermediate shells, located between the middle and console shells, are made of variable cross section along the length, contours, connecting thereof to the middle and console shells, are congruent to the contours of the middle and console shells respectively. Between two adjacent shells rings are mounted, in the lower parts of the middle and intermediate shells in the area of their connection by the rings, inserts are installed.
