Abstract
Over the last years in Kazakhstan the problem of passenger transport, concerning the moral depreciation of passenger cars, 40% of which are being used for more than 30 years, has blown up. Therefore, the road administration had to obtain the rolling-stock of light-weight type, such as “Tolgo Pendular” firm (Spain). Currently, the pilot runs of “Tolgo” designed for high-speed traffic along the normal railway between Almaty and Nur-Sultan, are carried out. At the same lime, the construction of cars of a new type gives rise for a number of questions.
