对运输工作以及铁路发展远景研究的分析表明,除了增加电气化线路外,还要大力发展内燃牵引线路。在采用内燃牵引的最繁忙线路上,货物列车的重量不久的将来将增加到5500～6000t,车站到发线的长度为1050m。采用八轴车辆编组列车时,列车重量将进一步提高到8000～9000t。内燃机车功率和牵引力的必要提高,较好的方法是提高其单节功率。计算表明:用双节式2×2941kW内燃机车来取代2×2206 kW内燃机车,可以使列车
An analysis of the transport and railroad development perspectives shows that in addition to increasing the number of electrified lines, there is also a need to develop internal combustion traction lines. On the busiest roads with internal combustion traction, the weight of cargo trains will increase to 5500 ~ 6000t in the near future, and the length of the departure line of the station will be 1050m. Using eight-axis vehicle grouping train, the train weight will be further increased to 8000 ~ 9000t. Diesel locomotive power and traction necessary to improve, the better way is to improve its single power. The calculation shows that replacing 2 × 2206 kW diesel locomotive with 2 × 2 2941kW diesel locomotive can make the train
