The article begins with a general description of computers now in use and their method of operation and instruction systems, particularly the models designated "Ural-1", "Ural-2", and "Ural-4" with passing reference to "Ural-14" and "Ural-16". The article also discusses electrical desk-top calculators with the remark that experience gained in using computers in experiments connected with calculation of rolling stock design shows that a number of problems can be solved without the use of electronic computers. Such problems as calculating traction drive, and assigning tolerances for springs with a small number of variants can usually be executed on keyboard calculators. Therefore when selecting the calculating means for solving each concrete problem it is necessary to estimate the volume of calculations required, the required accuracy of the result, and the cost of the calculating operation. The article concludes with a recommendation that most problems can be effectively handled by a semiautomatic calculating machine, such as the VMP-2. (Author)
