目前,铁路运输工作中的薄弱环节之一是机务部门,特别是采用内燃机车牵引的地区。这在很大程度上与机车功率不够和机车运用可靠性降低有关。机车运用可靠性的降低一方面是由于拥有的机车已陈旧,另一方面是由于修理基地发展落后、许多备品和材料缺乏以及机务段修理干部不配套。要消除这些原因在大多数情况下都会牵涉到要大量增加机务部门设施方面的工程投资,改进物质刺激系统,解决运输部门工作人员的劳 At present, one of the weak links in the railway transport work is the maintenance department, especially the area where diesel locomotives are towed. This is to a large extent related to insufficient locomotive power and reduced locomotive reliability. The reduction in the reliability of the use of locomotives is due partly to the obsolescence of the locomotives owned and, on the other hand, to the backward development of the repair bases, the lack of many spare parts and materials and the lack of support for the locomotive depot repair cadres. In order to eliminate these causes, in most cases, it will involve substantial investment in engineering projects in the maintenance department, improvement of the material stimulation system, and resolution of labor in transportation departments
