FIELD: railroad transport.
SUBSTANCE: proposed railroad vehicle frame is made up of one lengthwise beam linked up crosswise beams at least two of which being furnished with supports to attach running gears. At least one lengthwise beam is formed by at least one horizontal or shaped sheet, and at least one vertical sheet. At least upper edge of aforesaid vertical sheet features two rectilinear sections and curvilinear section arranged at the sheet center in vertical plane, its convexity being directed upward. Aforesaid curvilinear section is located between axles of aforesaid running gear supports. Curvilinear section height above rectilinear section exceeds tolerance for beam lengthwise deflection, but does not exceed 1% of the distance between supports axles.
EFFECT: lower frame weight, higher load-carrying capacity, improved traction and aerodynamics.
