济南西机务段配属由美国引进的ND_6型电传动内燃机车共79台。担当济南——徐州、济南——德州和济南——天津间(四对直货)货物运输任务。牵引定数为3200～3700t,最大坡道为9.6‰(换算坡道)。截止1985年10月底总走行公里为9573075km。通过一年来的运用实践,我们认为该型机车具有牵引力大、检修工作量小、节油性能较好等优点,适合于长交路轮乘制和多机重联。但由于机车处于早期故障期,运用和检修人员对这种新型机车的构造、性能还不十分熟悉,机车本身也暴露了一些工艺、材质、设计等方面的质量问题。因此,运用一年来先
Jinan West Locomotive Depot Belonging to the United States imported ND_6 electric transmission diesel locomotive a total of 79 units. Responsible for Jinan - Xuzhou, Jinan - Texas and Jinan - Tianjin (four pairs of direct cargo) cargo transport mission. Traction set number of 3200 ~ 3700t, the largest ramp was 9.6 ‰ (converted ramp). As of the end of October 1985, the total kilometers traveled 9573075km. Through the use of practice over the past year, we believe that this type of locomotive has the advantages of large traction force, small maintenance workload, good fuel economy performance and the like, and is suitable for a long-wheel drive system and a multi-machine reconnection. However, due to locomotives in early failure period, the use and maintenance personnel of the new locomotive structure, performance is not yet very familiar with the locomotive itself also exposed some of the quality of the material, design and other aspects. Therefore, the first year of use
