叙述了以科洛姆纳内燃机车制造厂为首的一些单位在高速客运机车的研究、试验中取得的进展和试验结果，着重介绍了四轴转向架的结构特点。目前，俄罗斯тэп80型内燃机车动力学试验速度已达到260km／h，1993年补充试验时达到272km／h，其动力学性能及其对线路的作用等均符合技术要求的规定，达到了较高的水平。专家们建议，以тэп80型内燃机车走行部为基础，先制造速度为250km／h、然后再制造速度为300～350km／h的单节功率为8800kW的八轴电力机车。
The progress and test results of some units headed by Kolomna Diesel Locomotive Manufactory in the research and test of high-speed passenger locomotive are described. The structural characteristics of the four-axle bogie are emphatically introduced. At present, the test speed of тэп80 diesel locomotive in Russia has reached 260km / h and reaches 272km / h in supplementary test in 1993. Its dynamic performance and its effect on the line meet the requirements of the technical requirements and reach a higher Level. The experts suggested that the eight-axle electric locomotive with a single power of 8800kW should be manufactured at a speed of 250km / h and then at a speed of 300 ~ 350km / h on the basis of the эт80 Diesel Locomotive Department.
