机车车辆的维修对于机车车辆的寿命周期费用具有很大的影响，其中一方面是维修费用的原因，而另一个越来越重要的因素是完好率。这种影响不仅在机车车辆的机械部份，而且在电气部份显得越来越重要，可以看出，费用从按计划的预防性维修向非计划的纠正性维修转移。本文根据各种影响因素及有效衡量值，阐述了怎样才能使维修方式适合不断变化的条件。
Maintenance of rolling stock has a significant impact on the life cycle costs of rolling stock, one of which is the reason for the cost of repairs, and another, more and more important, is the intactness rate. This effect has become more important, not only in the mechanical parts of rolling stock but also in the electrical part, where it can be seen that costs have shifted from planned preventive maintenance to unplanned corrective maintenance. Based on various influencing factors and effective measures, this article explains how to adapt maintenance methods to changing conditions.
