In connection with the forthcoming development of deep quarries, two basic requirements will be even more insistently applied to the rolling stock: reducing the dead weight of the train and the ability to overcome large gradients. Reducing the tare coefficient of the train about two times and overcoming gradients of about 80‑100% in railroad transport can be realized by the usual replacement of locomotive traction by motor cars. However, at these gradients the required number of motor cars is large. This complicates the operation of rolling stock and increases capital and operating costs. For example, according to V. E. Rosenfeld, E. V. Chebotarev and B. G. Kamenetsky, the economic feasibility of using motor cars is limited to a slope of only 63%.

The solution to the problem of transportation of large volumes of rock mass at open‑pit mining operations depends to a great extent on increasing productivity and reducing the cost of rail transport. An important role should be given to the improvement of wagon designs, which account for 65% of metal consumption and up to 40% of maintenance, repair and depreciation costs in relation to the total costs of rolling stock. As the analysis of transportation equipment operation at open pits shows, the current situation with the equipment of open‑pit mining operations with dump cars cannot be considered satisfactory: a) the range of manufactured dump cars is small; b) the strength of the main components of the wagon is low in general, and especially when excavators with large bucket capacity are used for loading; c) the tare coefficient and the length of the wagon are high; d) the operating costs of the wagon fleet are significant. Therefore, it is necessary to design and manufacture new types of dump cars for open‑pit mining operations.
