苏联铁路在拟订机车车辆的基本折旧率和大修折旧率时,认为最主要和最复杂的问题是规定机车车辆最有利的使用年限。其所以复杂是由于使用年限与机车车辆的磨损密切相关。规定机车车辆平均使用年限。不仅要确定其使用年限,而且在使用年限内要充分保证其能力,生产率和效果。机车车辆自投入使用开始、在以后的运用期间,并不能总是保证其技术运营性能。当继续使用这些机车车辆时,由于实际磨耗和无形损耗,在技术上已经证明是不可能和经济上不合理时的平均年数。当机车车辆达到下列情况时就应当报废。
In formulating the basic depreciation rate and the overhauling depreciation rate of rolling stock, the Soviet Union considers that the most important and complex issue is to stipulate the most favorable useful life of rolling stock. Its complexity is due to the age and the wear and tear of rolling stock is closely related. The provisions of the average service life of rolling stock. Not only to determine the useful life, but also in the life of the full guarantee of its ability, productivity and effectiveness. Rolling stock vehicles from the beginning to put into use, in the later period of use, and can not always guarantee its technical performance. When these locomotive vehicles continue to be used, the average number of years technically proven to be impossible and economically unjustifiable due to actual wear and tear and invisible wear and tear. When locomotives reach the following conditions should be scrapped.
