技术上的必要性、运用要求的经济性和法律规范,导致西德联邦铁路机车采用有计划的维修。维修制度的基础是对各种型号机车制订的维修计划,包括使用期限、维修等级和维修周期等参数。据根《铁路-建筑-运营规程》第32节的规定,意义最大的维修等级是隔一定的走行公里或一定的时间周期后进行的大修(Untersuchung)。在检修周期之间的运行安全性和运行可靠性,通过定期维修(Fristarbeiten)来保证,西德联邦铁路采用双重维修系统:在机务段进行定期保养和较小的修理作业,在修理工厂进行检修和较大的修理作业。
The technical necessity, the application of the required economy and the legal norms, lead to the planned repairs of the German Federal Railroad locomotives. Maintenance system is based on the various types of locomotive maintenance plans developed, including the use of time, maintenance levels and maintenance cycle and other parameters. According to Section 32 of the root Railroad-Building-Operational Regulations, the most significant level of repair is an overhaul which takes place after a certain number of kilometers or a certain period of time. Operational safety and operational reliability between service intervals, guaranteed by the regular service (Fristarbeiten), is a double maintenance system for the West German railways: regular maintenance and minor repairs at the depot and overhauls at the repair shop And larger repairs.
