Motor car competitiveness in markets distant from motor car manufacturing area depends on the value of logistics outgoings. A motor car compact loading in special railroad cars allows reducing considerably outgoings mentioned. According to a common loading order a railroad car capacity within the limits of extreme dimensions throughout the height is not completely used as it exceeds considerably a total height of two motor cars. In this connection it is possible to compact a loading layout only through the location of a motor car rear part of a front motor car under the engine jacket of it following motor car at their inclined fixation and longitudinal orientation. It allows stowing additionally two motor cars in every railroad car. The motor cars of some models cannot be stowed in two rows in one deck. It is caused with that a total width of two motor cars exceeds extreme dimensions of a railroad car allowed for railway operations. The problem could be solved, if motor car loading in every deck is carried out on load floorings the surfaces of which have a tilt from the center of a railroad car to its side walls. At the inclination of about 100 the projection on a horizontal plane of maximum cross dimension of a motor car on a level of passenger seats decreases by 25 mm. Space saving makes 50 mm on two parallel rows. As a result a two-row rail freightage of motor cars becomes possible in every motor car deck with the width 1680 mm common for products of Volzhsky Motor Car Works. At the expense of this way a length of haul economically feasible increases considerably.
