Abstract: 1. A high-speed module of a transportation system, comprising a streamlined body with smoothly conjugated therebetween sphere-like front portion, drop-like middle portion having a flattened bottom surface and conical rear portion as well as two rows of drive-connected wheels, characterized in that the module is further provided with one or two bodies with a conical rear portion similar to the first body and rigidly connected to it by coupling members providing air gaps between side surfaces of the bodies, wherein each of two wheel rows is arranged symmetrically beneath the extreme body, the rear portion of each is designed of alternating curvature body in the longitudinal direction, wherein the points of conjugated surfaces having different curvature signs of the rear portion of each body are spaced from the points of conjugated surfaces of the middle and rear portions of the body at a distance satisfying the ratio: wherein: L5 is the distance from the points of conjugated surfaces of the rear portion of the body having different curvature signs to the points of conjugated surfaces of the middle and rear portions of the body, m; L1 is the length of the middle portion of the body between the points of the conjugated surfaces of the front and rear body portions with the flattened bottom surface of the middle body portion, m. 2. The module according to claim 1, characterized in that the length of the middle portion of the body and the distance between wheels row satisfy the ratio: wherein: L2 is he distance between the wheels row, m. 3. The module according to any one of claims 1 and 2, wherein the lengths of the front, middle and rear portions satisfy the ratios: wherein: L3 is the length of the front portion of the body from the extreme front point to the conjugated surface line of the front portion with the flattened bottom surface of the middle portion, m; L4 is the length of the rear portion of the body from the extreme rear point to the conjugated surface line of the front portion with the flattened bottom surface of the middle portion, m; 4. The module according to any one of claims 1 to 3, characterized in that the area of the maximum cross section of the middle portion of the body and the area of the maximum cross section of the rear portion of the body satisfy the ratio: wherein: Srear is the area of the maximum cross section of the rear portion of the body, m<2>; Smiddle max is the area of the maximum cross section of the middle portion of the body, m<2>. 5. The module according to any one of claims 1 to 4, characterized in that the drop-like upper and the flattened bottom surfaces of the middle portions of each body are conjugated according to the provision: wherein: H1 is the maximum height of the upper part of the body passing through the points of the body with vertical position of the tangent, m; H2 is a corresponding height of the lower part of the body passing through the points of the body with vertical position of the tangent, m. 6. The module according to any one of claims 1 to 5, characterized in that the side surfaces of the middle portion of each body are designed with a negative curvature in a longitudinal direction. 7. The module according to any one of claims 1 to 6, characterized in that the lower surface of the middle portion of each body is designed with a negative curvature in a longitudinal direction. 8. The module according to any one of claims 2 to 7, characterized in that the coupling elements between the first and each of additional bodies are embodied in the form of aerodynamic profiles.
